Advice; How to convert a smoke detector to use a recorded message
Hi,
First post...be gentle!
Trying to find someone to guide me through converting a normal, off the shelf, home smoke detector so that it emits a pre-recorded message, rather than the usual siren.
Anyone?
Thanks

use the signal from the beeper to activate a locking relay, or transistor. This activates the "play" button of a voice recorder. Kinda an ugly hack, but it should work.

u r welcome. Let us know how it comes along. This has amusing possibilities: "pardon me, but the house appears to be on fire" ( in a very soothing voice). Or: "dinner is ready, come and get it

Definitely the latter in my house LOL
It's a project to stop cigarette smokers gathering outside my office window. I thought a smoke detector that alerted them they were in a no smoking zone would be a novel way to move them on.

if a voice warning doesn't work, add thunder, and a sprinkler

I'm not sure what @Toga_Dan means by a voice recorder but you can get greetings cards (or just the modules) that can record a message

same concept. Higher $, capacity, and quality. Digital audio recorders took the niche from tape recorders. Typical classroom audio recording.
