Access Control
LNL-1100 Series 2
The Lenel Input Control Module (ICM) provides the access control system with high-speed
acknowledgment of critical alarm points in monitored areas. The ICM communicates directly with
the Intelligent System Controller (ISC) either by 2-wire or 4-wire RS-485 communication. The ICM
has 16 configurable input control points and 2 output control relays. It supports normally open,
normally closed, supervised and non-supervised circuits.
The input circuits are scanned using an analog-to-digital converter. The digitized input status
signal is software-monitored and controlled, so that each input point can be programmed as a
supervised or non-supervised alarm point.
The output relays can also be configured for fail-safe or fail-secure operation. Each relay supports
the “On,” “Off,” and “Pulse” Lenel OnGuard software commands.
