Valcom v-9924b

VSP V 9924B 4 AUDIBLE RINGING UNIT Common Audible Ringing Unit provides an signal over the paging system when there is incoming call It is used between a telephone and the public address system PABX Station Port Electronic Key System Station Port Contact Closure Bell Buzzer ICM Activates via ringing voltage buzzer voltage or Capable of switching signal to 3 zones closure Uses standard 1A2 key system voltages Each zone is equipped with a 5 watt amplifier volume control Contains a punchdown block as part of the unit Compact size can be mounted on wall or in Automatically switches paging speakers from system to audible signal of the V 9924B the ring interval of the incoming call Variable pitch control Auxiliary contact closure power supply Materials Required Cat 3 or 5 twisted pair telephone cable Mounting screws and hardware x 4.55 W x 2.3 D H x 11.56cm W x 5.84cm D lbs 59kg Requirements V 9924B requires a 24VDC B battery and 50 mA idle and 300 mA maximum operating Requirements V 9924B requires interrupted ringing or buzzer or dry contact closure to operate The output the V 9924B will follow the interruptions of the The ringing voltage should be approximately and the current requirement would be 8 mA buzzer voltage should be approximately 18VAC the current requirement would be 10 mA The pulls approximately 3mA through a dry closure for activation Ringing and buzzer cannot be applied simultaneously Use only method of activation Manuals Online Key COMMON SIG SIG UNA or Ring Closure BATT 1 NO 1 COM 1 NC 2 NO 2 COM 2 NC 8 9 1 2 3 4 5 6 T IN R IN T OUT R OUT T IN R IN T OUT

board onto the mounting plate and lock place with screw provided Make connections Connections V 9924B can be activated via ringing voltage voltage or a dry contact closure When used buzzer voltage apply one side of the pair to SIG pin 11 or 26 and the other side of the to 18VAC SIG pin 12 or 27 For ringing connections put one side of the pair on SIG pin 11 or 26 and the other side of the to 105VAC SIG pin 13 or 28 The V 9924B also be activated by connecting one side of a dry closure to pin 7 and the other side of the dry to pin 22 Connections V 9924B Common Audible Ringing Unit is of switching up to 3 zones of speakers to the signal generated by the unit The device is to be placed in series with the speakers 1 IN pins 16 and 17 are connected to the output leads of the page control Zone OUT pins 1 and 2 are connected to the speakers 2 and 3 hook up in a similar fashion Refer to 3 for pin numbers Connections 24VDC from the power supply to pin 15 or on the crossconnect block and ground to pin 14 or Closure form C auxiliary contact closures are provided the V 9924B These contacts follow the input and may be used for special applications contact ratings are 1 amp at 24VDC Up all connections are complete and double apply voltage to the unit Place a call to the system and while ringing or buzzer is being to the unit or when the dry contact closure adjust the volume of each zone by turning the control clockwise for each zone Replace when all connections and adjustments are and lock in place using the 6 screw Manuals Online REMOVE COVER SCREW ACTIVATE LATCH TIE LOOP TIE

level Control pitch control has been provided to vary the pitch of warble ring tone see location in Figure 2 should different pitch be desired Generally this control not require adjustment ASSISTANCE trouble is reported verify power is being to the unit buzzer ringing voltage or closure appears at the unit and that there are broken connections at the punchdown block To test the unit a VOM and a lineman test will be required Use the VOM to check for from the power supply and to verify that or ringing is coming from the telephone The lineman test set can be used to check the warble tones on the T OUT and R OUT leads the speaker If a spare unit is available continue to by substituting a spare unit for the unit Manuals Online in troubleshooting is available from the When calling you should
