Form-C Relays - Programmable - TB8
Relay 1 (factory default programmed as Alarm Relay)
Relay 2 (factory default programmed as fail-safe Trouble Relay)
Relay 3 (factory default programmed as Supervisory Relay)
Relay Contact Ratings: 2 amps @ 30 VDC (resistive) and 0.5 amps @ 30 VAC (resistive)
Auxiliary Trouble Input - J6
The Auxiliary Trouble Input is an open collector, unsupervised circuit which can be used to
monitor external devices for trouble conditions. It can be connected to the trouble bus of a
peripheral, such as a power supply, which is compatible with open collector circuits.
All connections must be in conduit, less than 20 ft. (610 cm) in length in the same room.
Special Application Resettable Power - TB9
Operating Voltage: Nominal 24 VDC
Maximum Available Current: 500 mA - appropriate for powering 4-wire smoke detectors
Power-limited Circuitry
