Overview
The Lenel
®
Output Control Module (OCM) communicates directly with
the Intelligent System Controller (ISC) by either 2-wire or 4-wire RS-485
communication. Each OCM is an individually-addressed device, and
counts as a single device on all Intelligent System Controllers.
The OCM can be operated by either 12 or 24 VDC power. Each OCM
includes dedicated tamper and power failure input contacts.
The OCM has 16 programmable output relays that can be configured
for fail-safe or fail-secure operation. Each relay supports the “On,” “Off,”
and “Pulse” OnGuard
®
software commands.
