    I purchased two of these transmitters. one of the wired transmitter is not working after two days. Wiring was done as per schematic diagram. The other one is working perfectly in the same installation.

    Works great. I have designed it into a a circuit that when our doorbell rings, 10 seconds later a light goes on and then goes off and resets 15 minutes later. A home breakin deterrent.
