Series 3 Lenel® Input Control Module (ICM) provides the access control system with high-speed acknowledgement of critical alarm points in monitored areas. The ICM communicates directly with the Intelligent System Controller (ISC) by either 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 nonsupervised 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 failsecure operation. Each realy supports the “On,” “Off,” and “Pulse” Lenel OnGuard® software commands.
