Hey! 'Bout those GE home sentrys. Do you know pproximately when each model came out and how long each one was made? Also, where do you guys find these old catalogs and advertisements for these detectors? Thanks!

I’ll go for it:
8201-101, 8202-001, 8203-001: ~1975-76
8201-201, 8205-0, 8201-301: ~1980
8201-401C: ~1985
SMK-6 (plus other SMK series): ~1990
A few I’m not sure of. I do know the 8201-101 was the first and original Home Sentry, came out around 76 according to the ad I have. I’m not sure about the 8201-301 and 8205-0 since they have the same sensor but different horns.
