    There isn't too much to a wireless doorbell. It should be possible to examine the receiver and alter it to do the activate relay function. When it receives a valid code, so signal has to activate the chime function.

    Good luck!

    It should be doing that already. If it is not, you might have a button that is sticking on the transmitter, a relay that is sticking on the receiver, or you might have radio interference from some other transmitter that is keeping the relay energized.

    Well Sarge, we read that one differently. Wonder if the OP can straighten us out?

    Just tried my wireless door bell. Pushing and holding the button looks like it sends out only one coded signal. Holding it down doesn't repeatedly ring the bell. He may have to go to a push-on/push-off operation, with a toggle circuit at the receiver.

    Interesting!

    Well, think about how hard it would be to use IR to signal from a door to an annunciator around a corner in a different room. Anything that bright in the IR region would probably set the opposite wall on fire.

    beenthere,

    I meant, all my TV/VCR/DVD/Audio remotes are IR. redacejr's implication the his TV remote interferes with a wireless doorbell seems...well...remote. ;)

    I have converted a wireless door bell to operate a relay.
    Checked voltages on the receiver until I found one that would drive a transistor that would drive the relay.
    As resacejr said the relay will only be on for a few moments and will need a ratcheting circuit

    You could always connect to the flip flop, first press on, second press off.
