http://www.youtube.com/watch?v=K0UmE5PVpRg - Really cool demonstration of an antique London fire panel–features a trouble bell.
http://www.youtube.com/watch?v=WUPXTmWb_BE - See description. This system looks rather uncommon to be, especially the TrueAlert on a trim plate in march time…
http://www.youtube.com/watch?v=rYgt1vionCg - An older Simplex t-bar is pulled, which sets off 2901-9838 horns on 2903 light plates; signal coding is a very slow march time. It does sound like, however, that another alarm can be heard, but is indescribable due to the noise from the Simplex horns.
What you’re hearing is the reverberation of the horns. It does sound a bit like a high pitched alarm.
That looks like a System Sensor detector of some sort. The alarms sound like Federal Vibratone 450 horns, so it might be an old FCI system that used those horns on AV32 light plates (I see a LOT of old FCI systems with AV32 light plates.)
As for that TrueAlert on the trim plate, that’s because they are replacing older alarms. I’ve seen that before.
It’s a System Sensor 100 series detector. I have one in my collection. As for the signals, they do sound like Series B Vibratones but slightly lower pitched. Do remember that Fire-Lite also rebranded the Series B Vibratone–this could be an old Fire-Lite system as well.
One of those firefighters should secure his mask–it’s hanging by the air hose. It puts unnecessary stress on the coupling and it could make the whole unit go out of service for a while.
http://www.youtube.com/watch?v=-27_3KPWucs - Unusual smoke detector in code-3–sounds like a high-pitched horn (older?).
Uh, no. That’s a car horn. If you look to the left when the “alarm” sounds you can see flashing lights and a silver bumper.
Didn’t notice that until now, and yet I can’t seem to understand how the car alarm could have gone off…
And yet… I can not seem to understand how people do not read the description in the video.
“As he was lighting the grill I set off my alarm from inside.”
Not reading the description… a regular occurrence with my youtube videos.
Test of an LED Exceder! Evidently they sent him the wrong cover for it.
http://www.youtube.com/watch?v=Qge65aUC888 - This unusually high-pitched hi-lo alarm, which sounds an awful lot like a bird. It may be coming from the detector on the ceiling (:05-:06).
http://www.youtube.com/watch?v=Ms0Kl8ikUQY - (explicit language–go to 5:28) I have never heard this kind of whoop before, and I am curious as to know what kinds of alarms these are.
http://www.youtube.com/watch?v=DIrbjqxsfT0 - (:12) Alarms go off as part of an earthquake/fire drill (unseen 7002T h/s and distant piezo alarm in continuous(?)).
http://www.youtube.com/watch?v=LLR82kAUeeM - This is an interesting concept of a red, rotating beacon (similar to what is seen on older emergency vehicle apparatus) used in conjunction w/ an unseen 6" bell as part of what I would assume is a fire station.
http://www.youtube.com/watch?v=ZJ3I1PljCpU - This area (in a foreign country, supposedly), instead of using a traditional American alarm sound, uses a siren coded to yelp.
http://www.youtube.com/watch?v=6QOM5cfFqd0 - Really interesting; white LifeAlarm speakers on white 2903 incandescent light plates mounted on the ceiling–signal coding is 41XX series slow whoop–the lights, however, pulsate on and off at 30 bpm march time.
http://www.youtube.com/watch?v=iOrDEI4c1mQ - (bad quality) Mechanical horn in continuous, with some sort of ceiling-mount strobe.
NICE FINDS!
This is the first time I have ever seen a white 2903 plate. Now I know they exist(ed)
Also, that is a V33 Strobe in that video.
Not surprisingly, it’s the 4100U/ES Slow Whoop. Obviously that building used to have a Simplex 2001 or 2120 voice-evac system that was upgraded. Those are really hard to find due to them being replaced with 4100Us or similar.
I also kind of recall seeing white 2903 light plates once at an old high school (or maybe they were silver, or yellowed from age) with mechanical horns behind them, but the school was torn down last year (they also had some Gentex SHGs.)
That’s the 4100U slow whoop, and the flash rate is actually 20 bpm (aka, “slow march time”). Still a good vid, usually if there light plates involved the lights are either programmed to remain on steady or flash at 120 bpm march time.
