Product Installation Drawing
Installation:
The Fire Alarm Communicator provides sockets for two Form-C relays (P/N:411RK) rated for 2.0 amps @ 30 VDC (resistive). Relay 1 must be installed in the main circuit board socket labeled K6 and Relay 2 must be installed in the socket labeled K5.
- As a safety precaution, it is highly recommended that all power be removed from the main circuit board before installing the optional relays
- Position the relay module so that the largest gap between the first set of pins and the second set is to the left as illustrated in Figure 1
- Carefully align the relay module pins with the socket holes, making certain that the two pins on each end of the relay line up with the two holes at each end of the socket
- Press the relay firmly into place, being careful not to bend any of the pins
Programming:
The relays are programmable for activation on fire alarm, host panel trouble,
fire supervisory, process monitoring, total communication failure, DACT
trouble and security alarm. Refer to “DACT Programming” in the Fire Alarm
Communicator manual. Addresses ‘85 – 88’ are used for programming relay
functions and enable.
Note: Relay connections may be power-limited or nonpower-limited,
provided that 0.25″ spacing is maintained between conductors of power-limited
and nonpower-limited circuits.
Relay 1 – Shown Programmed for Alarm, Supervisory, or any other function
except DACT Trouble, Host Panel Trouble and Process Monitoring (relay contacts
shown in deenergized condition with power applied to Fire Alarm Communicator)
Relays automatically change to energized condition when programmed for
Trouble.
Relay 2 – Shown Programmed for DACT Trouble, Host Panel Trouble or
Process Monitoring (relay contacts shown in energized condition with power
