Hi, I am a newbie here. I stumbled on this thread while researching for Entronics Corp, to figure out what happened to them. It turns out they got bought out in the late 70s and they disappeared. However my aunt has lived in her house since approx 1978 and still has the original smoke detector/alarm made by Entronics, a Z-100 model. It is still hard wired in the circuit and has the little red ready light visible. We will need to upgrade to a current smoke detector, so this one will be “retired”. This one still has the factory sticker inside the cover and the little red “Test Weekly” sticker stuck on the outside of the cover. Anyone had any experience with these early detectors?

Welcome!
I have some experience with Entronic Vigilante units, I used to have a Z-700, similar in appearance to the Z-100 but took a 12.6 volt Mercury battery instead of being hardwired. These always used Radium 226 instead of Americium, the sensor was quite unique and consisted of a small chamber and a “target”, and they all had Kobishi CLB-27 squealer horns (hardwired one used a transformer). Vigilante’s are quite rare these so I’d definitely hold on to it.
