This chapter provides anumber of examples, each describing a specific systemconfiguration. You can use these examples and quicklyadapt them to meet your own configurationrequirements.2.1.1 PlenaThe Plena Voice Alarm System is part of the Plenaproduct range. Plena provides public address solutionsfor places where people gather to work, worship, tradeor simply enjoy themselves. It is a family of systemelements that are combined to create public addresssystems tailored for virtually any application. The rangeincludes mixer, pre-, system- and booster amplifiers, asource unit, digital message manager, feedbacksuppressor, call stations, an ‘All-in-One’ system and avoice alarm system. Each element is designed tocomplement all others thanks to matched acoustical,electrical and mechanical specifications.2.1.2 Application areasTypically, the Plena Voice Alarm System is used tocreate small systems that must comply witih emergencyand evacuation standards, medium-sized systems inwhich one call channel is enough and large systems thatconsists of many small zones.The application areas of a Plena Voice Alarm Systeminclude:• Schools, see section 2.2.• Swimming pools, see section 2.3.• Shopping malls, see section 2.4.• Hotels, see section 2.5.Other areas include: factories, high-rise buildings, officebuildings, recreational facilities and small airports.2.2 Application: School2.2.1 IntroductionSchools are typical example of applications with a largenumber of zones each with a relatively low outputpower requirement per zone. The main priorities arespeech intelligibility and compliance with IEC60849standard (or equivalent).2.2.2 RequirementsIn addition to mandatory voice alarm functionality forevacuating staff and students, Econtroller systems forschools should also include chime tones for notifyingthe start/finish of lessons, plus public addressfunctionality for individually calling classrooms orpublic area. BGM is not essential. Since a classroom hasa low ambient noise level, one loudspeaker is usuallysufficient, keeping the total power requirementrelatively low. Outside areas such as playgrounds andsports fields will require weatherproof hornloudspeakers.table 2.1: Summary of requirementsRequirements30 zones (typically 20 to 60 zones).Speech intelligibility is the main priority.Low power requirement (one loudspeaker) perclassroom.Fireman’s panel by main entrance.Call station in main office.Additional public address functions such as chimetones desirable.BGM in recreation areas is optional.2.2.3 SolutionThe Plena voice alarm controller handles messagerouting to 6 zones, the remaining 24 zones require fouradditional 6-zone routers. The office is equipped with acall station plus keypads for individually addressingzones, while a fireman’s panel (with overall priority) isbuilt in by the main entrance.2.2.4 Power requirementsThe voice alarm controller features a built-in 240 Wbooster amplifier, making it possible to drive up to 40loudspeakers with a power handling capacity of 6 Weach.

Thischapter first describes the functionality of each of thePlena units and explains their usage. Further on in thischapter, for each of the units, an overview is provided ofthe connectors, controls and indicators.NoteRefer to the Configuration Software Manual(9922 141 10381) to configure the triggerinputs.To connect the trigger inputs, refer to section 4.7.LBB1990/00Voice Alarm Controller3.2 Voice alarm controllerThe voice alarm controller (LBB1990/00) is the heart ofthe Plena Voice Alarm System. The voice alarmcontroller (further referred to as “controller”) centrallymanages and distributes emergency calls, business callsand background music (BMG). A single controller isable to serve and manage 6 loudspeaker zones. If morezones are to be served, extra routers can be connected(see section 3.3). Like this, up to a maximum of 60 zonescan be served. The controller is equipped with aninternal booster (see section 3.2.4) and an integratedmessage manager (see section 3.2.5). All Plena units tobe used, can be connected to the central controller.Trigger input/24V DC outEmergency1 2 3 4 5 6Business1 2 3 4 5 61 2 3 4 5 624VDC outVOXSwitch24VDC out10k10k1 2 3 4 5 6VOX Switchfigure 3.2: Trigger inputsfigure 3.1: Voice alarm controller (LBB1990/00)3.2.1 Trigger inputsThe rearside of the controller provides a terminal blockfor the connection of 6 EMG and 6 business triggerinputs. The EMG trigger inputs have a higher priority inbeing served, than the business trigger inputs. Thetrigger inputs can be used to signal events to thecontroller. To each trigger input, a prerecorded messagecan be assigned and broadcast to one or more zones orzonegroups.3.2.2 Loudspeaker zonesThe controller can serve 6 loudspeaker zones. Incompliance with IEC60849, the supply to each zone isredundantly designed. For this purpose, on the rearsideof the controller, there are two zone output terminalblocks (A and B).

Optionally, a spare external booster can beconnected (see also section 3.3.2). The externalbooster will only be activated when the internalbooster fails.• In 2-channel mode, an external booster (see alsosection 3.3.2) must be connected to the controller.The internal booster of the controller amplifies theBGM and the external booster amplifies the calls. In2-channel mode, calls do not interrupt the BGM.If one or more routers (see also section 3.3) areconnected to the controller, to each router, twoadditional external boosters can be connected. See alsosection 3.3.2.3.2.5 Internal message managerThe controller has an internal message manager, whichmanages and distributes all prerecorded messages andchimes. Up to 255 prerecorded messages can be storedas wave files (.wav) in an EEPROM, and can be usedboth in emergency and in business calls. Wave files canbe created and uploaded to the message manager, froma PC running the Configuration Software.NoteRefer to the Configuration Software Manual(9922 141 10381) for details about creatingprerecorded messages for the messagemanager.3.2.6 SupervisionThe controller integrates all required supervisionfeatures, in accordance with the international standardIEC60849 applicable for emergency systems. Variousfunctions of the controller are supervised. Supervision isswitched ON by default. Supervision can be switchedOFF by setting the supervision DIP switch in the OFFposition (see section 5.3).

Routers and RCPs areconnected to the controller using an RS-485 CANinterface. If any of the CAN stations fails during thenetwork check, a network error is reported.5.3.3.1 OverviewThe supervised functions can be configured with a PCrunning the Configuration Software. Using theConfiguration Software, supervision for each functioncan be turned ON or OFF. The default settings arementioned in table 5.2.5.3.3.4 Message supervisionIf supervision is enabled (see section 5.3.3), the internalmessage manager of the controller is supervised. Thismessage supervision consists of a check-sum mechanismfor the wave player and a pilot tone check for the audiopath.table 5.2: Default supervision settingsSupervised function Default setting SeeProcessor ON 5.3.3.2.Network OFF 5.3.3.3Messages ON 5.3.3.4Line supervision * ON 5.3.3.5EMG microphone ON 5.3.3.6Trigger inputs * OFF 5.3.3.7Mains power ON 5.3.3.8Battery power OFF 5.3.3.9Internal amplifier ON 5.3.3.10VOX 20 kHz input OFF 5.3.3.11External amplifier ON/OFF ** 5.3.4* Can be further configured using theConfiguration Software.** Depends on position of the 2ch operation switch.5.3.3.5 Line supervisionIf supervision is enabled (see section 5.3.3), allloudspeaker lines are supervised, including theloudspeaker lines of any possibly connected routers.Line supervision consists of:• Short-circuit supervision.• Impedance supervision.• Short-to-ground supervision.Short-circuit supervisionIf supervision is enabled (see section 5.3.3), thecontroller continuously monitors all loudspeaker lines inthe system for short-circuits. If a short-circuit with a loadimpedance of < 10 Ω is detected, the line is consideredto be short-circuited. In that case, the line output is shutdown within 200 ms.NoteRefer to the Configuration Software Manual(9922 141 10381) for details about adjusting thesupervision settings.5.3.3.2 Processor supervisionIf supervision is enabled (see section 5.3.3), theprocessor of the controller is supervised by a watchdog.If the watchdog receives a reset trigger, the Processor resetindicator on the front panel of the controller turns ON,the program memory is checked and the processorresumes operation within 10 seconds. When the fault isacknowledged and reset the indicator turns OFF.Impedance supervisionIf supervision is enabled (see section 5.3.3), thecontroller measures the impedance of all loudspeakerlines in the system at regular time intervals (by default,once every 100 seconds). The measured values arecompared with the reference values (see section 5.3) thatare stored in the controller. If the difference is biggerthan a preset differential accuracy (by default, 15%), theline is considered faulty.5.3.3.3 Network supervisionBosch Security Systems | 2004-06 | 9922 141 10371en
