DCP-SOMA | Hochiki's UL Approved Fire Detection

Supervised Output Module | UL Addressable Fire Detection

DCP-SOMA Description 


The Class A Supervised Output Modules (DCP-SOM-A & SOM-AI) have been designed to provide application flexibility and quick response to emergency conditions. Flexibility is provided by a wide range of operating modes, including supporting multi-zone operations, and/ or functions, up to 16 different modulation patterns, and multi-state programming.


The operating parameters for the DCP-SOM-A & -AI are maintained by the module and do not require individual communication with the control system during emergency conditions to operate. The control panel simply broadcasts system conditions on the Signaling Line Circuit (SLC) and the DCP-SOM-A & -AI modules do the rest based upon the custom configuration. Each DCP-SOM-A & -AI provides a single Class B or Class A circuit rated for 2.0 Amps @ 24 VDC. Each DCP-SOM-A & -AI also requires a 24 VDC power source in addition to the SLC.
