[QUOTE="binky, post: 524214, member: 490"] You are forgiven, and apologies for being so rude, I'm not exactly in a good mood at the moment. However, as mod on this 'friendly' forum posting antagonising replies is not setting a good example to others. A simple 'what are you thinking of' question, or the like, would serve us all far better. Now, I am no expert on all things relay as it's been rather a long time since I used to build test gear, when 555 timers were the bees knees and seemed to be in everything. However, I'm guessing by fault the OP is referring to false alarm trigger, ie burn't the toast, and having triggered the detector is looking to control something else, although they havn't said what exactly they hope to achieve. So a mains powered relay , Normally Open, with a 12V control coil connected to the interlink of the smokes (I believe the interlink is 12v not 240V) should do the job provided what they are trying to control is 240V of course. The relay being non-latching so that when the false trigger is cleared the relay returns to N.O. state ie auto resets. Last time a did anything like that was about 15years ago, and I can't quite think what I fitted it for, but may have been an old style retrofit telephone autodial connected to an alarm panel. If the OP is just looking to remote silence interlinked detectors AICO already do a products for this, which I believe even has a phone app these days, which will achieve this without home made gadgets. We need more info. [/QUOTE]
