Description
The S54370-B2-A1 is a dual-input interface module that supervises and monitors two sets of dry contacts on a Siemens fire-alarm control panel signaling line circuit. It occupies a single loop address while responding independently to each input, and includes built-in ISOtechnology dual isolation meeting NFPA 72 Class X wiring requirements.
Built-in isolation lets it function as both an in/out device and an isolator, identifying short-fault location. It operates on 13VDC to 32VDC, draws 950μA maximum, and accepts 14 to 18 AWG wiring. A multi-color LED signals green, amber, or red status, and it mounts in a 4-inch square box.
