LNL-1100 Input Control Module
43
Installation
To install the Input Control Module, perform the installation procedures described in the following sections,
in the order in which they are presented.
43.1
Wiring
1.
Wire the non-supervised alarm inputs for power fault and cabinet tamper monitoring.
2.
Wire the software configurable alarm inputs.
3.
Wire the upstream host communication.
4.
Wire the relay outputs.
5.
Wire the power input.
43.1.1
Non-supervised Alarm Inputs: Power Fault and Cabinet Tamper
Monitors
The Input Control Module features two non-supervised alarm inputs that can be used for power fault and
cabinet tamper monitoring. These inputs are connected using the BA (power fault) and CT (cabinet tamper)
contact terminals on the Input Control Module board.
The BA and CT inputs are simple N/C (normally closed) contact closure monitors.
Wire the BA and CT inputs using twisted pair cable, 30 ohms maximum. (No EOL resistors are required.)
Note:
If either of these inputs is not used, a shorting wire should be installed.
43.1.2
Software Configurable Alarm Inputs
The Input Control Module contains sixteen (16) software configurable alarm inputs that can be used for
alarm device monitoring. Each of these inputs can be configured, via the Access Control software, as either
N/O (normally open) or N/C (normally closed) in combination with either supervised or non-supervised
wiring.
