When configured as supervised, the input circuit will report not only open and closed, but also open circuit, shorted, grounded*, and foreign voltage*. A supervised input circuit requires two resistors be added to the circuit to facilitate proper reporting. The standard supervised circuit requires 1K Ohm, 1% resistors and should be located as close to the sensor as possible. Custom end of line (EOL) resistances may be configured via the host software.348 — revision 6Hardware Installation GuideGrounded and foreign voltage states are not a requirement of UL 294 and therefore not verified by UL.The input circuit wiring configurations shown are supported but may not be typical:11K,1%1K,1%Standard Supervised Circuit, Normally Open ContactIN1IN2T B 11K,1%1K,1%Standard Supervised Circuit, Normally Closed Contact1IN3IN4T B 2Unsupervised Circuit, Normally Closed ContactUnsupervised Circuit, Normally Open Contact66.1.5Relay Circuit Wiring
