I would like to know how to make a standard bulldog car alarm key fob transmitter stay on permanantly sending out the panic signal while having an on/off switch to control it. Weve tried for days to get it to work but cannot get it to do more than a pulse mode, ie: Switch it on it sends out a burst signal and then shuts off. Any suggestions?
