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:If either of these inputs is not used, a shorting wire should be installed.Unsupervised Alarm Input Wiring.CABINET TAMPERGNDIN 2POWER FAULTGNDIN 1105.1.2Upstream Host CommunicationThe BRI uses Port 1 to communicate to the ISC. Port 1 should be wired as 2-wire RS-485 interface for multi-drop or extended distance communication.For RS-485 communication, the following type of RS-485 cable is required: 24 AWG (minimum) twisted pair (with shields). 2-wire RS-485 cable configuration should be used. The RS-485 cable should be norevision 6 — 527LNL-500B Biometric Reader Interface
