Access Control
LNL-1200 Series 2
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” Lenel OnGuard software commands.
