[. . . ] It will also commence when any fault is detected. The sounder will continue until the alarm or fault is reset. [. . . ] TheVoiceAlarmActiveoutputisprovidedtosignaltothefiredetectionsystemthat the Vocia system has been activated in emergency mode in response to an Alarm Input. A constant output denotes that an emergency message is playing. A pulsed output (1. 25Hz) indicates that an alarm is active but emergency messages have been silenced. TheGeneralFaultOutputisprovidedtosignaltothefiredetectionsystemthatthere is a fault in the Vocia system that could affect delivery of an emergency message. Connector Label Function Isolated Ground A1 A2 A3 A4 Rs Si Alarm 1 Input from CIE Alarm 2 Input from CIE Alarm 3 Input from CIE Alarm 4 Input from CIE Alarm Reset Input from CIE Alarm Silence Input from CIE Ground VA Voice Alarm Active Output to CIE GF General Fault Output to CIE The Voice Alarm Active and General Fault outputs pull low (to ground) when active. The outputs are monitored by the LSI-16 for open-circuit or short-circuit to ground or power supply and for over-voltage on the output pin (>35V DC). If incorrect conditions are detected a Fault is signaled. Output monitoring facilitatescompliancewithvoiceevacuationstandards. Formonitoringpurposesaload(maximum22k)mustbeconnectedbetween each output and a positive voltage source referenced to the LSI-16 Ground, at the far end of the connection to the CIE (i. e.

Outputsmaybepulleduptothissource;howeverthe total current drawn from the source must not exceed 100mA. If an external voltage source is used for the outputs, it must not exceed 35V DC and in addition to the output loads, must also be connected to the LSI-16 `External Supply Over-voltage Monitor' input (refer to LSI-16 User Manual) for monitoring purposes. Due to monitoring constraints, it is not possible to use both the LSI-16 internal 10V source and an external source. 5 ReaR Panel Connections from External Devices for Fault Indications Thesecircuitsareprovidedonasinglefive-positionplug-inbarrierstripconnector. All Inputs are fully isolated from the CI-1 and LSI-16 internal circuits. The Isolated Ground provides a circuit return that is not directly connected to the CI-1 and LSI-16 Ground. These inputs allow the signaling of faults from external devices to the Vocia system so it may indicate and log faults that could affect emergency operation. These fault signals are typically derived from contact closures on external devices. [. . . ] Power Supply Connections Thesecircuitsareprovidedonasinglefive-positionplug-inbarrierstrip. Inputs are provided for two 24V power supply circuits to drive the LSI-16. This facilitates standards compliance by providing a means of redundant connections. [. . . ]
