Overview of my GE 8201-2 Smoke alarm! (Feat. 8201-1)

Shoutout to my friend Sidney that I mentioned in this video, his channel is ‪@Vintagesmokealarmsmedia‬ and he knows a lot about GE smoke alarms, so if you like them too then be sure to give him a visit!
But anyhow, this is a quick demo of 2 out of my 3 total GE alarms in my collection, with the latest one having a video in the works as I am typing this.
Enjoy!

Very cool, this is one of general electrics last square models this one being the predecessor of the 8201-301. there's also a predecessor to the 8201-201, which is 8201-101, which uses the same battery mechanism as the 8201-201 but uses the pcb of the 8201-001. Now u know. also, can u please make a video of the 8201-301A?
