The NATIONAL TIME Addressable Control I/O module is an SLC loop powered device that provides a Class A or B monitored input circuit for connection to a remote switch alongside a 240V dry contact relay.
The Control I/O Module combines an initiating input and a relay output in a single device, with independent functions controlled by panel programming. The module's output features a form "C" dry contact rated for 4 Amps. DigiComm™ communication supports Class A, B, or X wiring and includes a built-in isolator module for Class A installations. This powerful communication protocol ensures reliable and accurate information exchange between modules and the Fire Alarm Control Panel. The module has large wiring terminals for easy termination, and addressing switches can be accessed under the cover plate without disturbing the wiring. The Control I/O mounts in a 4” square or 2-gang electrical box.
