An FRM-1 relay module interfaces with a PR-1 multi-voltage relay to control damper closure from the fire alarm control panel. Power is supplied from the fire alarm control panel or an external power supply connected to terminals T10 and T6. The signaling line circuit loop connects to terminals T1 and T2 of the relay module. Rotary address switches set the loop address, and relay output contacts handle the damper closure signal.
