CONNECTION OF A CAR ALARM SIREN.
There is no direct input from a car alarm siren.
However, get an alert if the car alarm is activated, the siren can be connected to the ignition input
wire of the tracker.
This will produce the ‘ignition alert’ (page 10) – there is no ‘car alarm’ alert on this model of
tracker.
For (+) positive sirens (Mongoose)
No relay required, connect siren trigger wire to orange wire of tracker. Use diodes to
prevent
ignition sounding the siren and the siren turning the ignition on.
For (-) negative sirens (other alarm types)
Use a suitable low impedance miniature relay, not supplied, to convert negative
siren output to positive. Connect as below.
