Doug DeHaven The actual name for this cool unit, is a MASTERGUARD Single Station Heat Detector MODEL: MG 40 FT.
I picked this up recently for the collection. It is a cool piece of forgotten home protection history!
Back in the day, there where no electronic smoke detectors for the home, you had to rely on this fancy wind up ‘fire alarms’ they would ‘sense’ a high temperature from the fire and pop off the thermal disk and trigger the spring ring the bell. I go into more detail in this video,
I went about doing a full polish and shine on this unit, never seen it done! The bell is aluminum so would take a shine, but would take many hours to get the rough surface finish to a shine.
Here are some before shots.
Now to take it apart and start the polishing!
And the final result!
And here is the wrap up video,
Now lets test it!
I’M LOOKING FOR the disk that is attached to the front of the bell for model number MG-50 FT–HEAT DETECTOR ALARM
Looks like most sources have dried up for these sadly, I would try this company, they may still have old MasterGuard parts they could sell you!

If not, one on ebay for $25 has a disk you could use.

Hope this helps you!
I have an old masterguard Heat Detector Alarm model number MG-50 FT. that I believe is dated 1994.
I’m looking for the bracket that hooks up to this that allows you to hang it on the wall.
Do you by any chance know where I could possibly get a couple of these?
Thanks in advance
Randy
Randy,
Sadly, I do not have one, or have a source on one. I used a small loop of wire under the screw to make a hanger for a nail, that worked well for mine!
