User manual BIAMP MODEL 6702-B 6702-U

[. . . ] Vocia installations designed to comply with the requirements of EN 54-16 must be installed in accordance with Biamp recommendations detailed in this User Manual and in the Vocia VACIE Reference Guide (download from www. biamp. com). 3 fROnt Panel The CI-1 has three switches on the front panel and an internal (local) sounder, audible through the panel. Local Sounder Thelocalsoundercommenceswheneveranyalarminputreceivesanexternalsignalfromthefiredetectionequipment, controland indicating equipment (CIE) or equivalent. Local Sounder Silence Switch If the local sounder is operating, this switch may be used to silence it. The alarm or fault condition that caused the sounder to operate is unaffected by operating this switch. System Test Switch ThisswitchwillinitiateatestsequenceontheLSI-16.

[. . . ] System Fault Reset Switch A System Fault denotes that the LSI-16 cannot guarantee correct operation of the Vocia system in an emergency mode. A system fault can only be cleared by operating the System Fault Reset switch. Note that when the LSI-16 is powered up, the System Fault will be operational until the System Fault Reset switch is pressed. Press and hold the switch for two seconds to reset a System Fault. 4 ReaR Panel There are four main interconnection paths to the rear panel: · Connectionstothefiredetectionsystem(CIE); · Connections from external devices for fault indications · Connections to the LSI-16 · Power supply connections Each of these connection paths has several circuits as detailed below. Fire Detection System (CIE) Connections Thesecircuitsareprovidedontwofive-positionplug-inbarrierstripconnectors. The Isolated Ground provides a circuit return that is not directly connected to the CI-1 and LSI-16 Ground. AlarmInputs1through4aresignalsfromthefiredetectionsystem. Thesesignals placetheVociasystemintoemergencymodeaccordingtotheconfiguration determined for the input in Vocia software. The Alarm Reset Input cancels all active alarms in the system while the Alarm Silence Input maintains all active alarms but causes emergency messages to be silenced. Inputs are asserted by a positive transition to 12-24V with respect to the `Isolated Ground' connection. This transition should preferably be derived from a dry contact closure to a remote 12V-24V source, or to the CI-1 24V Reference Out (see below). TheVoiceAlarmActiveoutputisprovidedtosignaltothefiredetectionsystemthat the Vocia system has been activated in emergency mode in response to an Alarm Input. A pulsed output (1. 25Hz) indicates that an alarm is active but emergency messages have been silenced. Eachconnectorlabelisprefixedby"ToLSI-16. . . "ConnectorsarelocatedsothatwiththeCI-1mounteddirectlyaboveorbelowtheLSI-16, circuit connections may be made by directly connecting pin-for-pin to the vertically adjacent connector. Short interlinking cables are provided with the CI-1 for this purpose. Refer to the LSI-16 Operation Manual for the circuit functions of these connectors. Note that the LSI-16 PSU Fault, Protection Fault and Path Fault outputs are connected to the CI-1 purely for the purpose of providing required monitoring resistors (these outputs are not otherwise used by the CI-1). If these outputs are required for remote fault indications, the relevant connections should be removed from the Monitored Outputs connector of the LSI-16. As described in the LSI-16 Operation Manual, and external monitoring resistor will be required if these circuits are so used. 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. The Ground 1 and Ground 2 connections are internally connected together and to system ground. The VRef connection may be used as a voltage source for pull-ups on required fault inputs. [. . . ] The VRef connection may be used as a voltage source for pull-ups on required fault inputs. Loss of power to either power supply input will result in the LSI-16 detecting a fault. If standards compliance is not required for an installation, a single power supply connection must be paralleled to the two power supply inputs to avoid generating a fault signal.

Mounting the unit using four screws with washers will prevent marring of the front panel. [. . . ]
