Bridgewater State University fire alarms (2.0)

Fire Alarm General Discussion
1

Since the old thread was sort of a waste of bandwidth space and has been removed for now, and that my brother now goes to this school, I thought I would just start a whole new thread about the campus alarm systems (this time with NO pictures of everything.)
The university is very old (originally a state college), with buildings built between the early 20th century and today. All the academic-related buildings and at least two dorms have Simplex systems, while other dorms generally have EST systems. I will only be covering the academic buildings, starting with the east campus (it is divided by railroad tracks, and the two sides can be accessed by an underpass near the train station and a railroad crossing near one of the dorms.)

EAST CAMPUS COMMONS: The building has a Simplex 4120 voice-evacuation system, and is the original from when the building was built in 2002. All alarms are Simplex 4903-9148 speaker/strobes, even in restrooms. The pull stations are 4099-9003 dual-action T-bars with Stopper II covers over them, and the smoke detectors are addressable TrueAlarms (most of them on the campus are usually 4098-9714 heads on 4098-9792 bases.)
TINSLEY ATHLETIC CENTER:Also built in 2002, but this building has a Simplex 4100 voice-evacuation system, and the audible-visual signals are TrueAlert speaker/strobes, while restrooms have remote strobes. Again, the pulls are dual-action 4099-9003s, and the pulls in the gym have the red wire cages over them. Smoke detectors are the addressable TrueAlarms.
OPERATIONS CENTER: Simplex 4100U system, the original from when the building was built in 2003. The alarms are mostly TrueAlert horn/strobes, with remote strobes in restrooms and one above the panel. Again, the pulls are addressable 4099-9003s, and the smokes are addressable TrueAlarms.
BURILL OFFICE COMPLEX: Similar to above, but the panel is a Simplex 4010 (red cabinet version.)
MOAKLEY TECHNOLOGY CENTER: The building has a Simplex 4100 voice-evacuation system from 1995. Next to the panel is a Simplex-rebranded SAE annunciator of some sort, possibly for the sprinkler system. Alarms are 4903-9147 vertical speaker/strobes, while restrooms have the vertical 4903 remote strobes. Pull stations are Simplex 2099-9795 T-bars; one of them at one of the exits has a Stopper II cover over it. All the smoke detectors are the older-style Simplex TrueAlarms: one is on the smaller 2-wire base, others are on the bigger base. There are also Simplex beam detectors in the main lobby.
HART/BURNELL HALL: This is where my brother has had most of his classes so far. It was built in 1979, and the fire alarm system has been modified and upgraded over the yearsā€¦
ORIGINAL 1979 SYSTEM: Standard Electric Time system with SAE graphic annunciator outside the main entranceway. The alarms were Space Age 2DCD horns on AV32 light plates (no ā€œFIREā€ lettering) located in many areas, even in some restrooms! The pull stations were older Johnson Controls pulls, and smoke detectors were older Adaemco smoke/heat models.
CURRENT SYSTEM: Simplex 4100U system; the old SAE annunciator is still outside, but inside there is also a 4603-9101 LCD annunciator next to a large red Simplex transponder panel. Most of the alarms are now multi-candela Simplex TrueAlert horn/strobes, but a few restrooms that had the SAE horn/lights now have remote TrueAlert strobes (other restrooms that had those alarms now have TrueAlert horn/strobes in them as well!) The recently-renovated classrooms also have TrueAlert horn/strobes in them now, too. Many of the old JC pulls are still intact in the Burnell Hall wing, but most of them in Hart Hall were replaced with Simplex beak-glass 4251-30s (some time in the '80s and early '90s), and there are also a few Faraday F1G Chevrons and Simplex 2099-9754s scattered around the Burnell Hall wing. Many of the old Adameco smoke detectors are still intact, but the renovated classroom wing have addressable TrueAlarm smokes. There are also a few 2098-9201 and -9202 smoke detector heads on 2098-9536 4-wire bases replacing older Adaemco smokes (and at least one conventional TrueAlarm.) New Simplex duct detectors were also installed during the upgrade, and there are 2098-9806 test stations on the ceiling in certain areas as a result.

The West campus has many older buildings, so it gets a bit more interesting hereā€¦

RONDILEAU CAMPUS CENTER: The system is a Simplex 4100, installed some time in the mid-1990s to replace an older Standard system from when the building was built in 1970 (the building still has a Standard time system.) At the main entrance is a 4603-9101 LCD annunciator, and below it is a Simplex graphic annunciator showing the system zones, meaning that many areas of the building use conventional devices! Most of the alarms are Simplex 4903-9219 horn/strobes, even in restrooms, while renovated areas like the cafeteria and student life offices have TrueAlert horn/strobes. Most of the pull stations are Simplex 2099-9756 dual-action T-bars, except in renovated areas, which have addressable 4099-9003 pulls. There are some old Standard/Chemtronics heat sensors in some areas, but the renovated areas, the auditorium and near the elevator (redone in 2010) have addressable TrueAlarms.
BOYDEN HALL: Originally built in 1924, this is the most famous structure on the campus, and initially had a fire alarm upgrade in 1979. The current fire alarm system is a Simplex 4100, replacing an older 2001 panel (an old Simplex trouble bell is still connected to the 4100.) A 4003 voice control panel is also outside the renovated auditorium. Most of the alarms are Simplex 4051 horns on 4050-85 light plates (with black ā€œFIREā€ lettering on the lens), and most of the pull stations are Simplex 4251-20 T-bars. There are also several older Simplex 4259-36 smoke/heat detectors around the building, along with some 2098-9201 and -9202 smoke detector heads on 2098-9536 bases and a few replacement conventional TrueAlarms. There are also some 4255-5 heat sensors in a few areas (one of them was replaced with a TrueAlarm heat sensor.) The renovated offices and classrooms have TrueAlert horn/strobes and addressable TrueAlarm smoke detectors, and the auditorium (renovated in 2008) has TrueAlert speaker/strobes, along with a few horizontal 4903 speaker/strobes. Pulls are addressable 4099-9003s, and again, the smokes are addressable TrueAlarms.
HARRINGTON HALL: The building was built in 1926 and renovated in 2003. It currently has a Simplex 4020 fire alarm system with TrueAlert horn/strobes, 4099-9003 pull stations and addressable TrueAlarm smoke detectors.
TILLINGHAST HALL: Built in 1916, their current Simplex 4100U InfoALARM voice-evac system was installed in 2007. The alarms are mostly multi-candela TrueAlert speaker/strobes, with remote TrueAlert strobes in restrooms (and one right by the panel), and again, there are addressable 4099-9003 pull stations and TrueAlarm smoke detectors. A couple of old disconnected ESL smoke detectors can also be found in a couple areas (one of them rebranded by Autocall,) and outside there is a Wheelock RSS weatherproof strobe.
ART CENTER: This is the oldest building on the campus, built in 1904 and renovated in 1974. The current system is a Simplex 4002 (small version, replacing an old 4208; the 4002 panel is installed right next to the old 4208 cabinet.) The alarms are Simplex 4051 horns on 4050-80 light plates (no ā€œFIREā€ lettering on the lens this time), and the pulls are break-glass 4251-30s. There are also a few 2098-9201 smoke detector heads on 2-wire 2098-9637 bases, obviously installed when the 4002 was put in. This is the only fully-conventional fire alarm system on the campus.
HUNT HALL: Prior to its addition/renovation, the panel was a Simplex 4020. They might still have it, but Iā€™m not sure. They still have the existing stuff prior to the renovation (installed around 2001), with TrueAlert horn/strobes, 4099-9003 dual-action pulls, addressable TrueAlarm smoke detectors, along with Simplex beam detectors in one hallway. The new wing from last year has the same devices.
OLD SCIENCE BUILDING: This building was built in 1964, presumably with an old Gamewell FlexAlarm system, and was torn down last year. Prior to this, it had a Simplex 4020 system with TrueAlert horn/strobes installed everywhere, even in classrooms (restrooms had remote TrueAlert strobes), 4099-9003 dual-action pulls, and TrueAlarm smoke detectors in most areas, except classrooms, which had the heat sensor version.
NEW CONANT SCIENCE CENTER: This building is brand-new, and was opened this past September. The panel is most likely a Simplex 4100ES voice-evacuation system (no surprise!) Most of the alarms are TrueAlert speaker/strobes, but curiously some areas have remote TrueAlert speakers with remote TrueAlert strobes installed next to them! The smoke detectors are addressable TrueAlarms, and the pulls are most likely 4099-9003 dual-action T-bars. There is a video of the system going off on YouTube, and the alert tone is Slow Whoop.
MAXWELL LIBRARY: Built in 1971, and the main three floors were renovated between 2005-2007, and part of the ground floor renovated recentlyā€¦
OLD SYSTEM (prior to 2005): Standard Electric Time system with Standard Vibratone 450 horns, flush-mounted in most areas (but a few horns were surface-mounted); at least one of the lecture halls and presumably other areas had remote Standard ā€œFIREā€ lights. Pull stations were the old round Standard 200177s.
CURRENT SYSTEM: Most likely a Simplex 4100U; there is a 4603-9101 annunciator near the main entrance. The first to third floors and the renovated Starbucks and theater in the ground floor have multi-candela TrueAlert horn/strobes (restrooms and a few other areas have remote TrueAlert strobes). Parts of the basement still have the old Standard 450 horns, but many others were removed, some with TrueAlerts installed in their place, others with the horn removed and a metal plate installed behind the flush-mount grille! The ground floor still has the old Standard pulls, but other areas have Simplex 4099-9003 dual-action pulls. Many areas, including the ground floor, have addressable TrueAlarm smoke detectors.
KELLY GYMNASIUM: My brother and I actually used to go to a fitness program for kids here when we were younger, so I got to see the old fire alarm system when the building was originally built in 1957!
OLD SYSTEM: An old Edwards system with projector-style ā€œFire Hornsā€ in several areas, several of them red, some blue, others brown! Pulls were older-style Edwards 270-SPOs (with the old Edwards shield logo on the bottom.) There were also 6-inch IBM bells in several areas, presumably they used to be class-change bells. I also remember the swimming pool room having NO alarm signals in it (I could tell there used to be an Adapt-a-horn in there as well, but only the round mounting bracket remained.) Outside, a round ā€œregularā€-style surface-mount Adapt-a-horn was installed near the main entrance (also with ā€œFIRE HORNā€ label.)
CURRENT SYSTEM: The building had its fire alarm system redone in 2008. Currently they have a Simplex 4100U InfoALARM voice-evacuation system. The alarms are mostly multi-candela TrueAlert speaker/strobes in many areas (the alarms in the gyms have those metal wire covers on them), but restrooms have remote TrueAlert strobes, and the shower rooms have Wheelock ET70WP speaker/strobes. Pull stations are all addressable Simplex 4099-9003s; the pulls in the gyms have sounder-less Stopper II covers over them, while others are uncovered. The smoke detectors are addressable TrueAlarms, and the swimming pool room has Simplex beam detectors. There is also a Simplex 2098-9806 test station in the main gym with an STI cover meant for alarm signals over it!

Any comments?

Iā€™d like to see some pictures of the older systems, if you have them. :slight_smile:

I do, but ImageShack is being a pain all of a sudden. I do plan to upload them to another server. Unfortunately I do not have any pics of Kelly Gymā€™s old system, but I do have pics of the old Maxwell Library and Hart/Burnell Hall systems, along with the Art Center and the older stuff at Boyden Hall.

OK, hereā€™s some pics of the old stuff that I have (I do wish I had a picture of the old Edwards system at Kelly Gymnasium though!)

This is pretty much the old Maxwell Library system in a nutshell. IDK if any of these are left anywhere. The building was built in 1971, and their Simplex 4100U system installation began in 2005. So far, the above three floors have been completely upgraded, and as of 2012, the little theater in the basement has been, too. Those horns are Standard-relabeled Vibratone 450s. At the time I took this, there were still plenty of old alarms in the ground floor level.


At least two of the Standard horns werenā€™t flush-mounted.


I also found a couple of these remote ā€œFIREā€ lights in a lecture hall. I imagine there used to be more on the above floors before the Simplex system was installed. I think it would have made more sense to have more of these lights in areas with just horns, or even use Standardā€™s old retrofit light plates on the hornsā€¦

480Ɨ640 51.2 KB

At a few exits on the ground floor, these addressable TrueAlarm smoke detectors can be found (note the old Standard pull in the background.) There are also TrueAlarm detectors in the Starbucksā€™ area, which has TrueAlert horn/strobes that were installed during the initial system installation.


On the first two floors, the old alarms were removed in this manner; the original grilles are intact when installed on cinderblock or brick walls, but the horns have been removed. Also note the TrueAlert next to it (they are all 4906-9127 multi-candela horn/strobes.)

This is what the old system was like in Hart/Burnell Hall, where my brother has most of his classes in.


The original Space Age graphic annunciator from 1979 (panel was an old Standard system, but it has since been replaced with a 4100U.)

480Ɨ640 25.3 KB

This is what the system was originally like when the building was built. It was all SAE 2DCD horns on AV32 light plates, and Johnson Controls pull stations.


Old Adaemco smoke detectors. Many of these are actually still around.


They even had these alarms in some of the restrooms!

480Ɨ640 19.2 KB

All of the alarms are now Simplex TrueAlert horn/strobes (a few of the restrooms now have remote strobes, other restrooms have horn/strobes.) Most of the pulls in Hart Hall are now Simplex 4251-30s, but there are also a few 2099-9754 single-action pulls around the building. The Burnell Hall section still has many old JC pulls.

480Ɨ640 28.3 KB

In the main lobby, we have a Faraday F1G Chevron pull underneath the TrueAlert (that was installed before Simplex took over), and next to it is a 4603-9101 LCD annunciator next to what looks like a transponder panel (the actual 4100U panel is beige-colored, and is in an electrical closet.)


Some of the Adaemco smoke detectors were replaced with these 90s-style Simplex smoke detectors, and some in the Burnell Hall wing with addressable TrueAlarms.


Old Gamewell annunciator from the original 1964 Conant Science building (which has since been torn down.) This was the only thing left from the old system I saw (the rest of the building had a Simplex 4020 system with TrueAlert horn/strobes; the new Science Center has a 4100ES voice-evacuation system.)


Old weatherproof annunciator outside Boyden Hall. I imagine this was installed during the 1979 renovation/upgrade (the building was built in 1924.)

480Ɨ640 45.7 KB

Note the old Simplex trouble bell above the 4100 panel. They used to have a Simplex 2001.


They still have many of the old Simplex 4051+4050-85 horn/lights installed, to my knowledge. IDK if they are 4050-81s or 4050-85s, but they are indeed dual-bulb and 24 VDC (as the horns are 4051s, not 4050s.) These are common throughout the building, except a few renovated offices and classrooms, which have TrueAlert horn/strobes, and the renovated auditorium and registrarā€™s office, which have TrueAlert speaker/strobes (they have a 4003 voice control panel outside the auditorium.)


One of the many Simplex 4251-20 pulls found throughout the building, which were also obviously installed when the 4051+4050-85s were. The renovated areas have addressable 4099-9003 pulls.


They also still have many of these older Simplex 4259-36 smoke detectors. Some were replaced with conventional TrueAlarms and 2098-9201/2 photoelectric detectors, but the renovated areas have addressable TrueAlarms.


ADT-branded smoke detector next to an old Simplex end-of-line cover plate. This was in the old registrarā€™s office before it was renovated last year.

The only ā€œcompleteā€ old system on the campus is currently in the Art Center, also the oldest building on the campus (though it was renovated in 1974.)

480Ɨ640 41.7 KB

Last I saw, they had a Simplex 4002 fire alarm panel, installed in the early 1990s. It is not only the oldest panel still in use, but is also the only conventional system on the campus (other systems all have addressable panels, even if they use zones/conventional devices.) Note the old 4208 cabinet installed next to the 4002; it is probably gutted and now used as a junction box.

480Ɨ640 29.5 KB

All the alarms are Simplex 4051 horns on 4050-80 light plates (this time without ā€œFIREā€ lettering.) The pulls are all break-glass 4251-30s, and are installed pretty high up (surprised Simplex hasnā€™t replaced this yet!) Interestingly, some of the alarms are installed the old way, like this (the horn lined up with the light plate)ā€¦

480Ɨ640 29.8 KB

Others have the 4051 horn sticking out like they usually do. This is the only one on a backbox, due to the brick surface (I often see 4051+4050-80s installed like this in really old buildings.)

640Ɨ549 56.3 KB

There arenā€™t many smoke detectors, but I did find several of these 2098-9201 photoelectric detectors, obviously installed when the 4002 was put in. They donā€™t have any sprinkler or heat detectors in here either.

Burnell Hall had a couple renovations to the former cafetorium and gymnasium rooms. The cafetorium was divided into two multi-purpose rooms and the gymnasium is now a dance studio room. They still have TrueAlert horn/strobes, but they arenā€™t on the wooden planks covering up where the old SAE 2DCD+AV32s from the Standard system were. The old Adaemco smoke detectors in these rooms were also replaced with addressable TrueAlarm smoke detectors, and the Johnson Controls pulls with Simplex 4099-9003 dual-action pulls! The rest of the building is still mostly the same, though a few ceilings got replaced, and they installed more TrueAlarms in the process.

A part of the original Conant Science Building from 1964 was saved, and was connected to the new science center and renovated. It still has the addressable TrueAlarm detectors and 4099-9003 dual-action pulls, but now instead of TrueAlert horn/strobes it has voice-evacuation like the rest of the building does (TrueAlert speaker/strobes installed pretty much everywhere, even in individual classrooms!) They also installed a 4100ES transponder panel in each electrical room:

As one could tell, they obviously donā€™t have a Simplex 4020 anymore; it is now a full Simplex 4100ES voice-evacuation system!

The registrarsā€™ office in Boyden Hall was renovated and also had TrueAlert speaker/strobes installed, which probably are run off the 4003 voice control panel for the auditorium, along with the usual addressable TrueAlarms:

Other parts of the building still have the old 4051+4050-85 horn/lights and 4251-20 pulls installed in 1979, but IDK how much longer theyā€™ll be there (especially considering how Simplex sometimes gets to be kind of snobby about old fire alarm systems!)

A new parking garage was also built early this year. Not surprisingly, it has a Simplex system, but itā€™s voice-evac! The alarms are Wheelock ET70WP speaker/strobes, and the pull stations are those metal weatherproof Sigcom T-bars rebranded by Simplex:


Note the annunciator in the picture. Looks like a Simplex 4603-9101 or something with a weatherproof case on it! The system is probably another Simplex 4100ES or something. (If they went with horns instead of voice-evac, they probably would have used weatherproof TrueAlert horn/strobes.)

I know this is late but I have more of an in depth tour of the system:

Quite surprised to see these as original installs from 2001-2002! Itā€™s also quite interesting to note that all signals here are 30CD; no 15 or 110CD units installed. Iā€™d generally expect these to replace all the older 30CD Simplex speaker strobes.

Tinsley Center:

These are TrueAlert speaker strobes, but with no TrueAlert marking. There are actually speaker strobes in the bathroom. Prior to this the more specific model numbers of the speaker strobes is Simplex 4903-9357, which all of them are 75CD speaker strobes, with the exception of the lower floor of the gymnasium which has Simplex 4903-9358 speaker strobes, which are 110CD with cages over the alarms. Itā€™s quite interesting that everything else is 75CD fixed.

May have made more sense to add more 4903-9425/9426/9427 horn strobes and 4904-9168/9169/9170 remote strobes, but itā€™s the installerā€™s choice.

Note; the second 9101 is newer than the 1st one! The 1st one is now gone due to the renovated restroom.

Operations center:

Simplex TrueAlert 15CD Horn and Remote Strobe Non Addressable of some sort (I think they are 9417s and 9331s SmartSync)
Simplex 4904-9176 by surprise!

Yep, pretty good recap. As I said, Hart/Burnell Hall originally had Space Age 2DCD+AV32 horn/lights on a Standard Electric Time system (likely an SET-7000, since it was installed in 1979).
Out of all the systems you posted, Boyden Hallā€™s is the newest. A Simplex 4100ES voice-evac system installed in 2015, replacing an older Simplex system with 4051+4050-85 horn/lights and 4251-20 single-action pulls. It even has the newest addressable Simplex pulls with the LED indicator (in this case, theyā€™re dual-action 4099-9006s). Those TrueAlert horn/strobes were installed back when most of the old devices were still there. Before being removed, the panel was a Simplex 4100+, likely replacing a Simplex 2001 (the old system was installed in 1979 or 1980).

Another thing about the ET70WPs in the Parking Garage is that they are a whopping 135CD! Very bright!

. They also make 185CD versions, too. There are a bunch of EST Systems with Genesis Horn strobes in Dorms (I donā€™t like EST Genesisā€™s very much at all. Iā€™m glad they got replaced with LED versions).

Yep. Iā€™ve also seen several dorms there with EST voice-evac systems using Genesis speaker/strobes, though the dorm rooms have smoke alarms with sounders that sound similar to the Genesis horns. Currently, JCI/Simplex now services those dorms.

10

Another thing; at the Swenson Athletic Field; thereā€™s a bathroom that has a System Sensor P2RL L-Series Horn Strobe

The Stonehouse Hall Across from the East Campus Commons also has mostly Simplex 4903-9148 Speaker/Strobes as well, but alongside -9148s thereā€™s also a few Simplex 4903-9149 Speaker/Strobes and a couple 4903-9150 Speaker/Strobes. Thereā€™s some 4904-9174 strobes in the bathrooms. Very neat system! Thereā€™s even 4903-9148s of different generations and thereā€™s even one new one mounted vertically, though itā€™s really not a huge problem at all.

Most of the strobes in this dorm are 30CD! This dorm was built in 2002 just like ECC and Tinsley. They have such brotherhoods with each other plus they have some of my favorite voice evacuation systems. Note; most of these speaker strobes including remote strobes tend to be in better shape than the 4903-9148s at ECC. The 4903-9148s at ECC have a lot of dust and some paint overspray, so itā€™s nice that these ones are in better condition. Itā€™d be cool if they brought some of those 4903-9149s in this dorm into ECC because thereā€™s some pretty large open areas in ECC that could use an even higher intensity strobe than what is already there. Everything in ECC like I said up above is 30CD which is a surprise. Itā€™s not too much of a concern, the functionality is more important. Thereā€™s speaker strobes mounted very close to each other quite frankly! Itā€™s very very interesting! And you canā€™t forget the 4903-9147s in Moakley; those are awesome!

Weygand Hall has Simplex 4906-9151 Speaker/Strobes. All the other dorms have Crappy EST Systems.

12

Yep, though lately JCI/Simplex has taken over servicing the dorms.

Another thing about Scott Hall Dorm as of October 18, 2024; there has been 6 Fire Alarm evacuations in this one semester! How crazy!!

Thereā€™s also some issues with the very stiff pull stations and synchronization issues with the strobe lights in Scott. I donā€™t like EST Genesis Speaker Strobes at all. Thereā€™s always a Winplex with the Simplex!

14

Woodward Hall Also Has Simplex 4906-9151 Speaker/Strobes and 4906-9101 Strobes. A funny story about DiNardo Hall is that the Speaker Strobes are EST Genesis G4R/G4RF-S?VM Speaker/Strobes and G1R/G1RF-VM Strobes, but funnily enough, one of the bathrooms has a System Sensor SpectrAlert Advance SR Strobe, :rofl::poop:!

15

Also, I want to clarify the coding and tone options chosen for each building;

RSUs Simplex 4903-9219 possibly 9215 or 9217 and other Horn Strobes are on Continuous Horn and they are extremely loud possibly the loudest fire alarms on campus

Scott Hall, Pope Hall, Crimson Dining, Student Apartments, Miles Hall and Dinardo halls EST Genesis Speaker Strobes play the Boston tone; Itā€™s very quiet.

DMF and possibly most other buildings with Simplex Speaker/Strobes play a Siren tone; kind of an obnoxious tone but gets the job done, but then it plays a message.

Buildings with EST Genesis Horn Strobes will just do the standard Code 3 they always do; theyā€™re loud but not as loud as RSU.

The buildings with SmartSync Horn Strobes will most likely do the Infamous Code 3; Theyā€™re louder than its 4 Wire counterparts and lower pitched. The 4903-9417 Horn/Strobes on Campus are pretty loud (I feel like I havenā€™t seen a single -9418 or -9419 on this campus), but I think the 4903-9219s in RSU are louder. Both are louder than 4903-9236s (which are not on campus).

Most buildings the strobes completely shut off when the alarm is silenced.

16

I think by ā€œsirenā€ you mean the Slow Whoop. Thereā€™s a video of the Science Centerā€™s fire alarm sounding the newer Simplex Slow Whoop tone.

As for the Campus Center, at least before the lobby area was renovated with voice-evac, I figured it would be a lot like this old SimplexTech videoā€¦

i.e. electromechanical 4903 horn/strobes on Continuous mixed with TrueAlert horn/strobes on Code 3.
Of course before Boyden Hall and the Art Center upgraded, they were probably louder than the Campus Center, since they had Simplex 4051 horns! And I remember a friend recalling the Art Centerā€™s system was on Continuous (though th light plates probably flashed on the other NAC). (Again, Boyden Hall now has a Simplex 4100ES voice-evac system, while the Art Center slapped TrueAlert horn/strobes onto the 4040-60 and 4050-80 light plates.)

17

If the TrueAlerts in RSU are Free Run, then theyā€™d probably do Continuous just like the Simplex 4903s! This goes the same for that one replacement 4903-9252 that replaced a -9219 not too long ago. It would just make a long ā€˜EEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEā€™ sound. Theyā€™re probably just trying to keep it consistent in RSU with the Free Run Horn Strobes and SmartSync Voice Evacuation. Then once again RSU also is renovating a section with some brand new Simplex TrueAlerts from 2024. Iā€™ll have to show you once that area is fully renovated. Plus RSU also has a couple brand new Simplex 4903-9427s from 2023. I know the TrueAlerts are Free Run because the strobes are unsynchronized

They look like this:

https://firealarm.com/wp-content/uploads/2022/05/Simplex-4903-9427-3.jpg
And they are 110CD, which is very bright. RSU has one of my favorite systems.

Now I do wonder what the 4903-9148s in ECC/Stonehouse Hall sound like, if they play the older Whoop, Hi-Lo or Newer Whoop, IDK. Just note that Stonehouse also has 4903-9149s which are 110CD, 4903-9150s which are 15CD and 4904-9174 30CD selectable strobes which are the same strobe intensity as the 4903-9148 speaker strobe and 4903-9253 horn strobe. Maybe the 4903-9357s and 9358s in Tinsley sound like that though they have a different voice panel, so they may sound like Moakleyā€™s fire alarms, except strobes would probably be synchronized unlike Moakley.

My guess for the Model Numbers of the EST Genesis Speaker Strobes is G4R/G4RF-S?VM or G4HFRN/G4HFRF-S?VMC, Pope Hall Also has Edwards Integrity 757-?A-SS?? Speaker Strobes, Enhanced I believe and a Couple Replacement LED Genesis G4SVRF Speaker Strobes. Some Xenon Genesis Horn Strobes have been replaced with LED G1AVRF Horn Strobes. The Genesis Horn Strobes are G1R/G1RF-HDVM and remote strobes are G1R/G1RF-VM.

DMF also does have a Simplex 4906-9153 White Speaker/Strobe and 4906-9154 Ceiling Speaker Strobe.

The Welcome Center does have more 4906-9151 Speaker Strobes (Most of them are set on 75CD since they are multi candela devices, but some on 15CD) and 4906-9101 Strobes set on 15CD

Plus, youā€™re right about the slow whoop! My apologies!

18

I think the system sounds more like this; just with no System Sensor Fire Alarms: https://m.youtube.com/watch?v=FpGPLMoR7WI&pp=ygUYU2Nob29sIGZpcmUgYWxhcm0gdGVzdCAx

The RSU also has some brand new 2024 model SmartSync Multi Candela TrueAlerts in a brand new renovated section. These also have the new Simplex logo. This RSU now officially has both Free Run and SmartSync TrueAlerts. The Free Run TrueAlerts are Fixed Candela and receive Continuous Power. All the 4903s are Free Run in RSU, no SmartSync.

Most of the 4903 Speaker/Strobes on Campus are selectable; however the strobes might be on SmartSync just for syncing purposes and to prevent seizures for the occupants. But since Moakley is an older building, their strobes are Free Run.

It is said the EST Devices are meant to sync automatically, but I have noticed some problems with the strobe synchronization. This seems like it could be problematic in Pope/Scott Halls since they have a lot of devices on the circuits. And the strobe intensity and speaker wattage might not be affected by this. The Genesis Speaker Strobes have a ton of customizability and are very compact and those are what is located for most FA Signals in both of those dorms built 1960 and renovated 2009.
