I believe they use Edwards/EST, Honeywell and Siemens. There are a few newer buildings with automated voice systems.
Sounds like a variety. It would be funny if they start using Autocall. Unfortunately these old systems are getting replaced for newer stuff that isn’t as reliable as the Autocall. Im glad Old School Fire Alarms save some systems, i wish there were someone that salvaged the systems with the old Federal Signal equipment.
Simplex Truealerts, don’t now what coding because thank god I have not heard them go off, I work at the Ann Arbor, MI Holiday Inn West. Here’s a list of each Ann Arbor school and their alarms
Clifford E Bryant, all Wheelock 7002Ts
Pattengill Elementary, Mostly Wheelock 7002Ts with an Wheelock Exceder
Tappan Middle School, Mostly Wheelock 7002Ts with a few mixes of different Models
-Gymnasium; a 7002T, red bell of some sort, an unknown Cerberus pyrotronics alarm, and a Wheelock AS. 2nd floor by computer lab: unknown faraday horn, one unknown faraday alarm near the pool entrance and one in the pool room itself. Pioneer High School; all wheelock NSs with RSS strobes in the main school, portables(now gone)had MASS system sensors. Regardless of what they were; they were LOUD and you did not miss the sound; though funny thing is at Pioneer HS, we missed a drill since all of the alarms were somehow disconnected in the portables and then in Pattengill elemetnary; we missed two and the staff were not happy about it.
Did he Salvage any Federal Signal Model As or B-9s since that what we used back in the 50s
Fire alarm system at my school:
Simplex TrueAlert horn strobe
Simplex TrueAlert remote strobe
Simplex QuickAlert horn strobe (old and new version)

I’m new here, but I’ve had some interesting alarm systems.
The first school I went to was a rural Class 1A school where every grade was on one campus, with the elementary having their own building and the middle and high school shared the building (sadly the high school closed right before I started Kindergarten).
-The first building I was in from K and 1st was built in 1999/2000. The system was I believe some sort of an FCI system (maybe an addresable 7200?) with the pull stations being FCI MS-6s, FCI rebranded Spectralert Classic horn strobes and strobes, and some form of an FCI ASD smoke detectors (can’t remember).
-The second building I was in from 2nd-4th was built in 1976, and originally had a 2 Simplex 4251 pull stations that I believed were tied to the school bell system. But I guess after the new building was built, the old elementary building had Gentex Commander 3 Horn Strobes in the hallway and Commander 3 strobes in the bathrooms. The pull stations were addressable FCI MS-7 (BG-12) pull stations, and some form of an FCI ASD smoke detectors in the hallways.
-The “mini gym” built next to it sometime after the 76 building also featured 2 FCI MS-7s (at the exits), 1 Gentex Commander 3 Horn strobes, and 2 strobes in the bathrooms. (Surprising, there were no stoppers).
-At the old school, the building was built in 1936, and only had one bell, one Gamewell Century in the office, and an ancient alarm panel. But, the detached cafeteria had a fire alarm system that was added in when they expanded it, because some of the alarms were on conduit, and some were mounted in the wall. The pull stations were Gamewell Centurys and Gentex Commander 3s.
-In 2011, a new “middle school” building was built with 4 new classrooms, a cafeteria and front office. And with the new building, came a new Gamewell-FCI E3 Addressable system. The pull stations were Gamewell-FCI MS-7AFs, the NAs were Spectralert Advance P2Ws and SWs, and some form of Gamewell-FCI ASD smoke detectors, along with 2 annunciators (some form of a black E3) in the new building, as the control panel was placed in the 2000 building.
-However, at the end of 5th grade I moved to a new school with quite an interesting mix of systems. The school I went to was built in the early 60s, and was continually added on up until 1999. As the elementary school would get its own campus in 2006 (it has Simplex Truealert Speaker-Strobes, Truealarm smoke detectors, Simplex 2099 pull stations, and I assume the voice evac panel is a 4003 because the building is only 1 story.
-The system is a Harrington Signal System (not sure how rare those are) that was installed in the late 90s. The NAs were rare Space Age Electronics VA4s in the hallways, gyms, cafeteria, and ag shop/home economics kitchen, and VA3 strobes in classrooms and bathrooms. The smokes were mostly Honeywell 2400s with some modern smoke detector replacements (I think SD335Ts?). One of the VA4s in the “mini gym” were replaced with an EST Integrity. The pull stations were Harrington Signal RMS t-bars with key resets.
-The band room was built in 1996 and was given a small FCI system, which had FCI MS-6 pull stations, FCI HE-8F horn strobes, FCI STW strobes, and some form of FCI smoke detectors. IN 1999, the band room got a science classroom/lab which got an additional 2 FCI rebranded Spectralert Classics and 2 additional MS-6s.
-In 2018, a new Gymnasium was built as the first part of a new high school. The new gym was given an Gamewell FCI E3 system with a voice evac panel, with the NAs being L-Series Spectralert Advance Speaker Strobes, and some rooms receiving L-series Ceiling mounted strobes, with pull stations being a mix of Gamewell FCI MS-7ASF single action and MS7-AFs dual action pulls. Don’t remember the smokes, but if I had to guess probably some sort of Gamewell-FCIs.
And they did another such upgrade this week, with the Back To School season upon us. This time, it’s the Science and Technology buildings, each having its’ own NFS-320 system installed, with the same devices as the buildings in the quote. But the system it’s replacing was only installed in 2011-2012! A Notifier NFS2-640 system rebranded by Johnson Controls served both buildings, with Wheelock Exceder horn/strobes, JBG-12LX pull stations and JC-rebranded Notifier smoke detectors and heat sensors. I suspect they did that because there was only one master box covering both systems, even back when they had separate fire alarm panels (Standard Electric Time “Alarmatic” systems when they were built in 1972, and then Faraday FireWatch II systems installed in the 1990s). When the NFS2-640 system was installed, they just put the new devices right where the old ones were, using adapter plates and such. But with these NFS-320 systems, they put in a second Gamewell master box to cover one of the new panels, and they plated over where the old devices were and installed the new ones in different locations, so now there are more horn/strobes in the buildings, even in classrooms (while the restrooms have remote strobes). The renovated science labs in the Science building kept their Wheelock Exceder horn/strobes (installed in the rooms during renovation), possibly because they were considered adequate enough in providing alarm signal coverage. Each NFS-320 also has a Potter PSN-106 power supply installed underneath.
Sorry for the Late response, You were right. The system did not contain a MXL, the whole system was (And still is) Conventional. The current Panel is a Simplex 4005, Not what I thought of previously.
