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.
