Lenel (LNL-1100-S3) Security alarm input control module board, series 3

The Lenel LNL-1100-S3 is a Series 3 Input Control Module for the LenelS2 OnGuard access control platform. Specifically, it provides 16 supervised input points and 2 Form-C output relays for monitored areas.

First, the ICM gives an Intelligent System Controller high-speed acknowledgement of critical alarm points. Then, it reports input state changes back to the ISC over RS-485. As a result, integrators can extend door, tamper, and auxiliary monitoring without adding controllers.

In addition, every input supports normally open, normally closed, supervised, and non-supervised circuits. Therefore, designers can match input wiring to existing devices on a retrofit. Furthermore, standard end-of-line resistors are 1K/1K ohm, 1%, 1/4 watt.
