I have done this. I used a ITI transmitter (long life) and a Mercury
switch attached to the input terminals. Dip the transmitter (once
programmed in to your system) in that stuff they sell to coat your tool
handles for protection. Then mount it on the "ledge" underneath the
front t bumper or somewhere else. As a call pulls up and slows
down/parks, the mercury will shift back and forth causing the
transmitter to transmit. On the ITI stuff, you can put it in group 25
(older panels) and it should be "non-supervised". This will cause the
alarm to chime anytime the car pulls up withing range.
