Wiring the Fire Relay
For Stand-Alone or FS2000 systems: Connect the initiating circuit wires to the four pin WECO terminal.
Install the wires into Pins 7 and 8 (for Normally Open relay) or Pins 6 and 7 (for Normally Closed relays)
and firmly tighten down the slotted screws with a small screwdriver. There is an internal 10K ohm
resistor between Pins 5 and 6 for circuits which require an End of Line (Supervision) resistor. One
common configuration is to Jumper Pins 5 to 8 and connect the initiating circuit to Pins 7 and 8.
Refer to Figure 4, Model SS3 Detector Wiring, for more details on relay connections.
