The SD500-AIM and SD500-MIM are addressable input modules for use with the Intelliknight fire alarm control panels (FACPs). The SD500-AIM addressable input module mounts to a 4″-square box. The SD500-MIM mini input module fits inside a single gang box. Both input modules are designed to be used with pull stations, water flow switches, and other applications requiring dry contact alarm initiation devices.
These modules are supervised, single input contact monitors. Using an EOL resistor, they monitor for alarm contact closures and for open circuit wiring fault conditions
