The Hochiki R2ML-I is a dual relay module from the R2ML/H series, giving an intelligent fire alarm system two independently configurable Form C contacts on a single SLC address for functions like fan control, elevator recall, door release, or auxiliary notification. Each relay can be programmed separately for normally-open or normally-closed operation depending on what the connected equipment needs, and the module supports both Class A and Class B SLC wiring, with up to 127 devices sharing a single loop. The "-I" variant specifically adds a yellow LED for short-circuit indication alongside the standard bi-colored polling/activation LED.
