Has anyone tried using a microphone to monitor a smoke and CO detector and alert you if the mic goes over a certain decibel? I know this would be a rigged setup, but I’m trying to get around buying a wired security system just for the smoke a CO capabilities.
Most of the modern smoke/co detectors have 3 wires to connect them.
The common and red wire form a signal to other detectors … if one goes off they all go off.
They make relays that you can also connect to this; The relay can trigger a Z-Wave door switch.
I also go the other way and have a relay inject a 9 volt signal on these wires and then I have a multi-room Z-Wave alarm.
I’d be interested to hear if you get anywhere with this ritu - I have a motorised deadlock which I control with a Fibaro switch, but there’s no feedback to say the door has actually locked apart from an audible alarm from the lock if there’s a problem. I’ve been wondering how to detect this and feed it into Vera.
Thanks for the replies. I may look more at the relay method first. I like the idea of having a 2 way connection and making the siren multifunction. Plus, that may prevent my dog from triggering the alert if he barks loud enough.
