I have an interest in smoke detectors and am looking to see if anyone has encountered an Earli-Gard VocAlert Smoke Detector circa late 1980s early 1990s. Interestingly, this is a detector that came with a programmable voice module. I would love to get my hands on one to see what type and brand of embedded processor was used and the general board layout was used for its design. this is one of the earliest models capable of being programmed with directions and has about a 100 word vocabulary. Thinking about reverse engineering it. Does anyone have or encountered an Earli-Gard VocAlert Smoke Detector? If so, are willing to part with it? Information regarding this particular detector would be helpful as well. The few things technical details here and there have been mostly in Chinese. Thank you!
 
The Earli-gard line of smoke detectors was produced by Square D up through the 80's. I do not remember them having a 'voice' version.
 
Sorry to do this: BRK already remade this style smoke under the first alert name. We're you looking to make it to allow custom messages recorded by the user? That would be interesting, not sure if that feature would pass listing, but it's a thought. It only has an 11 word vocabulary. They are battery operated and wirelessly interconnected.

It's not exactly the same maybe you can use one of these and make it better. Gotta love innovation!

I have an TV remote from that era that is called "Voice command" it too only has a few word vocabulary and recognized so few few words it was stupid and I put it back in the box and shelved it, If I can dig it back up I'll see what it is.

maybe the electronics are the same?

Re: Interesting

Ah, I see, Square D is now a subsidiary of Schneider Electric. I wonder what happened to Square D's smoke detector division and their assets.

Interesting thought regarding the record-able voices. Now come think of it, I wonder how a user actually selected the 100 words on the VocAlert Smoke Detector back in the early 1990s to provide a coherent message when the alarm turns on.

Regarding the remote, they might share some standard components but unsure if these would be particularly directed to operating an alarm and detecting smoke.

Anyway, thank you all for all your inputs!
