Not notifier. Hint: company which produces them/Company which owns the brands. i actually dont know what brand it is but is one of those 2 in the hint. And its running clip.

  • The strobe is a Kidde rebranded Wheelock strobe
  • You are correct about the speaker!!

This is a Simplex 2901-9838 horn behind a Simplex 2903 visual plate. From the front, you cannot tell if it is a light plate or a strobe plate. Nice find!

(Sorry about no pic, my OnePlus phone won’t let me put in pics, click link to see pic)

I have posted about my district’s old high school recently in other topics, but I have another question after uncovering an old video.

I saw an old video from 1988 from that school (the actual video’s topic is not relevant). At one point, they show the principal’s office.

Here is what I’m talking about:
(Look in the far corner of the room.)


I have been in this school enough to know that the current fire panel (a Simplex 4100U) is mounted on the wall directly in that spot where it looks like there is a different panel. Does anyone know what panel that could be? Also, does anyone know what that gray console next to it is?

The system at that time would have just been installed in the past few years. It was a Pyrotronics system.

If anyone could help solve this mystery, I would be extremely grateful. I have always wondered what the panel from this time period could have been.

If it helps, I know they used these detectors on at least part of the system because they left some in place when they upgraded to the Simplex system:



I saw quite a few of those on an Edward system the pulls were 270SPOs. I think the building was built in the 1960s

Whoa, where is that? Those are Edwards Single stroke bells; probably one of my all time favourite alarms out there.

I grew up around single stroke bells my whole life, and have taken a huge liking to them. They seem to be very rare now a days, with few in service still.

There at a college call Liu, post campus. Many of the alarm are old, some even from the 50s.


Found this at one of my local high schools

Looks like an Amseco SHB of sorts. Here’s an image of one I found on the internet (credits to uploader “Samuel”, pretty sure they’re on here too):

Here’s an easy one!

That’s actually an Amseco BZ-50P that was relabeled by Cerberus Pyrotronics. Plus, other mechanical horns such as the Federal Signal 450D and the Wheelock 34T were also given the HDC-24 model number.

Anyways, I haven’t seen one in person. But I heard an audio clip of it going off on Schumiweb; and it sounds similar to a 450D.
