Applications:
the alarm is used in a 12v or 24v automotive system.
it monitors the handbrake switch and the door frame switch to provide audible warning if the door is opened while the handbrake is not allpied.
once the alarm starts, it stays latched on until the handbrake is applied (even if the door is closed again)
So it reduces the risk of the vehicle being accidentally left unattended without the handbrake on
