------ Pleaseread thisManual carefullybeforeinstalling andusingtheproduct.-----
I. Product overview
TheSG-991Efire alarm horn/strobe (horn/strobefor short)isakindofproductmanufactured byourcompanytobeusedwith
bus-typefire alarmcontrolunits. Controlled by amicroprocessor,the horn/strobecanrealizereal-timecommunicationwitha
bus-typefire alarmcontrolunitandreceivethecontrolcommandssentbyit.Wheninarouting inspection,the red status
indicatorwill blink;afteranaccidenthappens, thehorn/strobewillstarttooperateafter
receiving astartupcommandfromthebus-typefirealarmcontrolunit.Theredstatus
indicatorwillremain litandthehorn/strobewill giveaflashingsignal andanaudible
alarm signal tonotifythepersons onthesceneof the accidentthatafire hasoccurred
onthesiteandofthenecessity totakerelatedevacuationmeasures, thuspreventing
thefire accidentfrombecomingamajor one.Thehorn/strobemaybe restoredtothe
monitoringstatusafterthe MUTEorRESET keyonthebus-type firealarm control unit
ispressed.
Thehorn/strobe maybeusedtogiveaudible alarmsandflashingalarmson the
scenesofaccidents. Itissuitable forplaceslikehigh-riseresidential buildings,public
places,hotels,amusementbuildings,factories,shopping centers,hospitals, schools,
officebuildingsand stock exchanges,particularlyplaceswithlowvisibility orthe
possibilityof generationof smoke.

4.Address coding:Whenahorn/strobeiscoded, itisunnecessarytodisassemblethe wireconnectingit
withthehostmachine;onlinecoding maybedone. Thespecific method isasfollows: Openthe cover
ofthe coding setup window,inserttheoutputplug (a four-pinconnector)ofthecoder intothe address
coding socket(the socketJ2inFig.2)ofthehorn/strobe,setthe coderwiththe coding function,
compilethecorrect address codeand presstheRUN keytocompletetheaddress coding.(Note: See
theUser’sManualofthecoder fordetailedoperationinformation.)

5.Usage:Do notconnectthe powersupplyuntiltheaddressofthehorn/strobehasbeen setand
confirmed and thefire alarmcontrolpanelhasbeen properlyconnected.After thefirealarmcontrol
panelissuccessfullyreset,thered statusindicator(seeFig.3for its location) ofthehorn/strobe will
blink.After the horn/strobereceivesanoperationsignal,thestatusindicator willremainlitand the
horn/strobewill givebothhorn/strobealarmsignals.After thesystemis mutedor reset, thehorn/strobe
will stopoutputting horn/strobealarmsignalsand the statusindicator willstart toblinkagain.
VI.Installation and debugging
Aspecialbaseisnecessaryduring the installationofahorn/strobe.AsshowninFig.4,theexternal
dimensionsofthespecialbaseare142×84×10mm(L×B×H).Thehorn/strobeissubjecttoafour-wire
non-polarity connection:Terminals 1and 2are respectively connectedwiththeterminals +24Vand GND
oftheDC power supplyterminals3and 4arerespectively connectedwiththeterminalsL1 and L2 of the
signalbusofthe fire alarmcontrolpanel. SeeFig.5.

Specificinstallationand debugging methods:
1. UsetwoM4screwstofixthematchedmountingbaseonthedesignated positionvia themountingholes
shownin Fig.4(the installationmay bedonehorizontallyorvertically. Chooseanytwoofthe sixmounting
holesforinstallation)asinstructedintheconstruction drawingandmakesurethematchedmountingbase
has been firmly installed.
2. Disconnectthepowersupplyofthefire alarmcontrolpanel and connectallthebases correctlyin theway
showninFig.5, whichis aconstructiondrawing.
Note: Whenthere arealotof horns/strobesinasystem, itis necessary toconsidertheloading capacity of
thepowersupplyofthe fire alarmcontrolpanel.AnexternalDC24Vauxiliarypower supplymightbe
necessary atthistime. Pleasefollowtheconstruction designdrawings.
3. Makesurethetypeofthe horn/strobematchesthetypegiven ontheconstructiondrawings.Useacoder to
code thehorn/strobeaccordingtothe addresscodemarked ontheconstructiondrawings.
4. After allthehorns/strobesareinstalled andchecked,connectthepowersupplyofthefire alarmcontrol
paneland conduct automaticlogin.
5. After ahorn/strobelogs intothe fire alarm control panel,thered status indicatorof the horn/strobewill blink;
afterthehorn/strobereceives an operationsignal,theredstatusindicatorwill remainlitandthehorn/strobe
willgivebothhorn/strobealarmsignals.Afterthesystemismutedorreset, thehorn/strobewillstop
outputtinghorn/strobe alarm signalsandthestatus indicatorwillrestoretothemonitoringstatus and startto
blinkagain.
VII. Precautions
1.Pay attentiontothe markingandpolarities oftheterminalsduring installationandwiring.
2.Donotmakedifferentproductssharethe sameaddress inasinglealarmcircuitorthesystemwillfailtooperate
normally.
3.Makesure duringinstallationthatthere are noobjectsin frontofthehorn/strobe thatblock the lightgiven bythe
horn/strobeand/orpreventthehorn/strobefromsounding.
4.Makethe installation complywithrelatedprovisionsoftheCodeforInstallation and AcceptanceofFire AlarmSystem
(GB50166-2007).
VIII. Maintenanceand inspection
1.As specifiedin nationalstandardCodeforInstallationandAcceptanceofFireAlarmSystem(GB50166-2007),atleast
quarterly testsshould bedonefor eachhorn/strobe.
