provide independent sensor input for other functions, such as tamper
detection.
The trip input is connected to the external relay by wiring one side of
the external relay to the TRIP IN terminal, and the other side to either
the GND terminal or to the chassis ground on the TG-1 Express circuit
board.
Note that trip inputs are normally wired such that there is a 2.2k
Ω
resistor in parallel with the external relay, so that a tamper condition
(i.e. a cut wire) can be detected.
The functionality of the trip input can be customized at installation
time using an ordinary phone set or a lineman’s butt-set, in a similar
manner to other Telguard programming options. The relevant POTS
programming commands are:
Mem

When the trip input functionality is being used, closing the trip contact
will cause the Telguard device to send a message to the Telguard
Message Center, which in turn will cause the TMC to send a message to
the central station. If the Telguard unit is configured to report restorals,
the contact opening will also be reported.
