Not exactly sure how to go about this and days of searching existing electronic diagrams has given me a vague idea of what components to use, but nothing concrete yet.
My idea is to intercept the wire coming from a smoke alarm that is used to link it to another smoke alarm and use the signal to activate a relay to physically switch off the mains power to the stove in the kitchen.
I think it would be best to put in a delay of about a minute or so to give the cook a chance to evacuate the smoke before turning off the stove power in the kitchen.
My initial design thought was just to use a simple time delay circuit with a 555 ic, but that will activate the relay after a minute even if the smoke has cleared and the smoke alarm is off and there is no fire danger.
Any help is much appreciated
