Input configuration C activates when the contacts are closed. This arrangement allows the unit to monitor for an open circuit fault in the electrical wiring before activation. A short-circuit in the wiring will trigger the unit.S1.5 ONS1.6 OFFNormal Open contact without ‘activate’ resistor, fault monitored for open circuit.Input configuration D activates when the contacts are opened. This arrangement allows the unit to monitor for an open circuit fault in the electrical wiring during activation.S1.5 ONS1.6 ONNormal Closed contact without ‘activate’ resistor, fault monitored for open circuit.Autronica Fire and Security AS | Tel.: +47 90 90 55 00 | E-mail: info@autronicafire.no | www.autronicafire.com | Page 5Single Monitored Input Unit – BN-303Descriptions of function options(See location of DIP switch S1 on the circuit board drawing)Function AS1.1 OFFS1.2 OFFS1.3 OFFS1.4 OFFFunction: Alarm condition signaling input.Number of addresses: 1
