VSP V 9923B 3 CALL UNIT manual provides instructions for identification operation and technical assistance for the V 9923B Code Call Unit V 9923B provides two or three digit code call via a loop start trunk port on a PABX or by use of a spare line button on a key system V 9923B code call unit complies with Part 68 of FCC Rules and Regulations and has been granted Registration BAFUSA 68753 KX N The equivalence is 0.1B and the unit requires a RJ21X connector accordance with FCC Rules and applicable tariffs code call unit may only be installed with the of the owner of the host system FCC Registration BAFUSA 68753 KX N will listed in the affidavits filed with the telephone it will also be recorded in the system log by installation and maintenance personnel The telephone company is to be notified of the FCC number when this code call unit is V 9923B is capable of providing code signaling paging purposes it provides for meet me of code call and provides talk circuit and tone Trunk level access on PABX station level Can be used with 1A2 type key systems Uses rotary or tone dial signaling two digit codes or 729 three digit codes Dial tone to calling party Coded tone output for paging systems Switch controlled code verification tone Automatically discontinues code sending when Capable of being used with another V 9923B to two link operation Uses standard 1A2 key system voltages Mounts on the wall in a key cabinet or in the Cabinet V 9923B Code Call Unit provides the necessary for 1 link of code call For an additional of code call another V 9923B is required two

precautions below before applying power to the equipment the equipment may be damaged and the warranty a b c power was previously connected or remove power before inserting removing unit from the amphenol caution when crossconnecting that two adjacent terminals are not together check all connections before power twisted pair wire for all connections d Valcom V 9923B code call unit may be mounted a key cabinet relay rack or on the wall near the frame When choosing a location it is that the loop resistance of the PABX or key are not exceeded the unit in a vacant space in an equipment rack or key system cabinet allowing enough at the rear of the unit to plug in an amphenol Mount a 66B type punchdown block near unit and label it per Figure 3 a 25 pair cable with a female connector from the to the connecting block The cable should be on the connecting block in standard color order on a row of the connecting block Verify connections before plugging the amphenol end of cable into the V 9923B code call unit to PABX connections required to connect the V 9923B a PABX are shown in Figure 4 The V 9923B a loop start trunk port from the PABX for If more than one link of code call is being the second V 9923B would require a trunk and the two trunks should be in a hunt group the PABX This arrangement allows access to second V 9923B if the first V 9923B is in use ADVISE PERSONNEL USING CODE UNIT TO ALWAYS WAIT FOR DIAL FROM CODE CALL UNIT BEFORE IN CODE NUMBER answer the code call requires a station from the If two code call units are being used two would be required and they would have to be a rotary hunt group also to Key Systems connections required to connect the V 9923B a 1A2 key system are shown in Figure 5 The T A and L leads are multiplied to all phones in the Use a spare pick up button and install a 10K 1 4 watt 5 resistor either in the phone or at the block in series with the A lead from each The V 9923B will discontinue the code call when it recognizes two phones off hook with 10K ohm resistors to ground on the A leads WHEN USING 1A2 KEY TELEPHONES TO AND RO LEADS THAT WERE USED PABX CONNECTION ARE NOT USED Manuals Online Connections connections required to connect the V 9923B a power supply are shown in Figure 6 Correct must be observed for the unit to function Connections V 9923B contains a tone generator and isolation to allow direct hook up to the paging amplifier The tones are applied to the output the coded sequence dialed into the unit The tones on the TT BK S pin 29 and the RT S BK 30 leads If tones are not required as in the case using claxton horns bells buzzers lamps etc a closure is available The contact is capable of 1 amp 125 Vac or 2 amps 30 Vdc current requirements should use the contact to a power relay which would switch the load switched make contact input is the IN lead pin 22 and the out lead is the OUT lead pin 21 the switched output of the V 9923B is used to a DC slave relay it is necessary to install a suppression diode in parallel with the coil of the Refer to Figure 7 for the appropriate Switches option switches are located through the back of unit near the amphenol 1 sets either two or three
