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 (e.g., a cut wire) can be detected. When the trip input functionality
is being used, closing the trip contact will cause the communicator to send a message that the TCC
will relay to the Central Station. If the communicator is configured to report restorals, the contact
opening will also be reported.
Trip Input Wiring Diagram
For supervision, use
2.2K
Ω
resistor at end of line
NOTE: Be sure to use a UL-approved 2200-ohm resistor if the trip input circuit will be supervised (e.g.,
Bosch P110BL, Bosch EOL-22K, Elk ELR 22). The trip input circuit is not supervised for ground
conditions.
UL/ULC Compliance Note:
The trip input feature shall only be used for supplementary signaling.
Initiating zones shall not be connected to the trip input.
