Title: Hardware Installation Guide.pdf
The sixteen (16) inputs that are available on the ICM are 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 unsupervised wiring. These alarm inputs are connected using Inputs 1 - 16.280 — revision 6Hardware Installation GuideEach input that is configured as a supervised alarm must also be terminated with two (2) 1K (1000) ohm resistors (1% tolerance - 1/4 (0.25) watt. N/O and N/C alarms are terminated identically). Resistors are provided with the module.Install the resistors as close to input device as possible.
