Hardware Installation Guide9InstallationTo install the ISC, perform the installation procedures described in the following sections, in the order in which they are presented.1. Wire the unsupervised alarm inputs for power fault and cabinet tamper monitoring.2. Wire the upstream host communication.3. Wire the downstream device communication.4. Wire the power input.5. Remove the plastic safety strip from the memory backup battery.9.1Wiring9.1.1Unsupervised Alarm Inputs: Power Fault and Cabinet Tamper MonitorsThe ISC features two unsupervised alarm inputs that can be used for power fault and cabinet tamper monitoring. These inputs are connected using the Input 2 (IN2) and Input 1 (IN1) contact terminals on the ISC board.Input 2 and Input 1 are both simple N/C (normally closed) contact closure monitors.Wire the Input 2 and Input 1 contacts using twisted pair cable, 30 ohms maximum. (No EOL resistors are required.)Note:
