The FRM‑1 is an intelligent, addressable relay module that provides two isolated Form‑C (DPDT) dry contacts for controlling auxiliary devices like fans, dampers, or door holders. It communicates over a two‑wire SLC (Signaling Line Circuit) using rotary address switches. The module operates at 15–32 VDC and draws up to 6.5 mA (LED on). It mounts into a standard 4″ square × 2⅛″ deep box and supports both Class A and Class B wiring supervision.
