I watched this video, and I saw a lot of interesting fire alarm devices. I thought you guys might be interested.
Here are some screenshots from the video:
This image shows a pull/break glass station that is likely original to the 1930’s building or was added not long after. It’s most likely a coded pull station of some sort.
Here is a “newer” Honeywell pull station that I saw.
These images show various smoke detectors, ranging from modern addressable, to what are likely early 1900’s AC operated detectors. Some Gentex smoke detectors can also be seen in the video.
I also saw some Wheelock MTs with LSM strobes in some parts of the building, but others didn’t have any visible signals (probably still using the original signals flush mounted in the wall or recessed behind plates.
What I’m thinking with this building is that they probably installed some Honeywell and Wheelock hardware in the 90’s to upgrade the protection in some areas, but they never finished doing a full system upgrade/replacement before those parts of the building became unused. In recent years, a new system has started to be installed.
If anyone has more insight as to why they seemingly have 3 generations of fire alarm systems in service in the building at once, please let me know.
I highly recommend watching the video, as it will provide a lot more context, and is just a great video overall.
