or programmed to output the selected pattern
• UL 864 Listed
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.
