My fire alarm pics

Well, North Junior High School STILL has that ancient Gamewell fire alarm system, similar to East Junior High but with Faraday 129 flush-mount horns:

As you can see, they still have the old IBM clocks and 4015-6A bells, too. (They also still have the Simplex 6400 master time panel.)

I also visited one of my old favorite teachers at the Raymond K-8 school across the street to catch up on old times, and I got a few more pics there too:


The Simplex 4051+4050-80 outside the library with the missing lens! Note the type of light bulb (it is bigger than on my 4050-80), and how the frame thingy the light goes into looks a bit different than my 4050-80 as well. I may post a comparison pic some time soon.


Here is the Simplex annunciator in the main lobby in Trouble mode. It doesn’t have any trouble alarm of any kind (no bell, buzzer or piezo), so it isn’t that noticeable unless you look right at it.


Note on the annunciator for the fire department or anyone else working on the system. (The tape was coming loose on one side so I had to hold it up.) According to this, it appears the Simplex 4010 panel is used for the duct detectors, and the 4208 panel is for everything else (i.e. the pull stations and heat sensors). It is apparent this annunciator was installed when the duct detectors were redone, which may have been in the 1980s or 1990s.


The Simplex 6351 master time panel in the main office. Note how it appears to be installed onto the original time panel cabinet (you can make out part of the label on the old panel behind the Simplex 6351.) They were considering putting the bells on separate circuits so the middle school students would have a separate schedule from the elementary school students.

Any comments?
