Having tired of ADT's lack of customer service and increasing charges I cancelled my contract and have installed a wireless system. I would like to make use the Accord bell/strobe but only have 5V available at unknown current from my new alarm. My idea is to use the 5 volt alarm signal to trigger a relay, how do I wire the Accord side of the relay? I assume it is 12V and I have a couple of spare 12V 1Amp power supplies.
Many thanks
