ARCHITECTS’ AND ENGINEERS’ SPECIFICATIONS
MODEL V-2003A THREE ZONE INTEGRATED PAGE CONTROL
The Three-Zone Integrated Page Control, Model V-2003A shall be a wall or shelf mounted, telephone compatible, three-
zone, one-way, page control unit with integrated power supply and single/warble tone input. The unit shall be optionally loop
start, ground start or contact closure start and shall be capable of recognizing either DTMF tones or rotary pulse for dial
selection of three individual zones and all call. The unit shall be programmable on a per zone basis for single tone and
interrupted warble tone, background music, and with the installation of the optional plug-in talkback module, handsfree talkback
or one-way page operation. System options shall include dial tone and ringback tone. The unit shall provide AGC circuitry for
voice page input.
The unit shall provide three individual one-way low level outputs, one for each zone. The one-way low level output shall
not exceed a maximum of -10 dbm. Individual handsfree talkback output shall also be provided with the installation of the
optional plug-in talkback module. All call shall be one-way operation only. Access of specific zones shall not affect features
programmed for other zones, i.e. background music shall mute only in the zone being paged while other zones programmed for
background music shall not be affected. Audio output signal levels must not exceed 1 watt for talkback.
In connection with a telephone system, the unit shall have the ability to provide loop current, the detection of which shall
indicate a request for service (in the loop start mode of operation). Ground start operation shall be available as an optional mode
of service request. In connection with a telephone system page port, a "dry" tip and ring connection with provision for contact
closure activation shall be provided. A battery feed switch located on the unit shall enable or disable the loop current option of
the tip and ring connections. A second switch shall select loop start or ground start service request options.
In connection with a telephone system supplying "A" lead control from each telephone, the unit shall also have the
ability to provide inhibit (speaker cancel) to allow handset to handset "meet me" answer to a page without the paging system
broadcasting the conversation.
The unit shall have the ability to provide a single tone and an interrupted warble tone over page. The single tone shall
be activated by a contact closure and shall follow the contact operation. The interrupted warble tone shall be activated by a
contact closure or a 90 Vac ring signal. The single tone shall have priority over the warble tone in the instance of coinciding
activation.
The unit shall provide the ability to program features on a per zone basis. A dip switch shall be provided for zone feature
and system option programming. Dialing codes shall be 1, 2, and 3 or 5, 6 and 7 for individual zones and 4 or 8 for all call. The
detection of the "#" tone shall return dial access.
The unit shall be equipped with a 50 pin male amphenol connector for input and output connections and an RJ11 jack
for page tip and ring input. Volume controls shall be provided for tones, background music and all call.
The unit shall provide a three conductor grounded power cored with NEMA 15-5P type plug for AC input and shall
provide auxiliary -24 Vdc and GND outputs. The outputs shall provide a total of 1.0 Amp of -24 Vdc for powering one-way
amplified speakers or other accessory devices. The chassis shall be AC grounded. The AC input shall be fuse protected at 1.0
Amp. The unit shall be UL Listed.
The unit shall have a power consumption of 1 Amp at 120 Vac. Page input shall have an impedance of 600 Ohms.
Music source impedance shall be 8 to 600 ohms. Music input level shall be -10 dBm nominal. Low level output impedance shall
be 8 ohms. Low level output level shall be -10 dBm nominal and must not exceed a maximum of 0 dBm. Operating temperature
shall be +32 to 104 °F (0 to + 40 °C). Operating humidity level shall be 0% to 85% non-condensing.
An optional Plug-in Talkback Module, Model V-9953, shall be available separately. It shall be a plug-in circuit board
compatible with the V-2003A to field upgrade it for handsfree talkback capability. It shall provide phone to speaker, speaker to
phone, tone, background music and all call page volume controls. System options shall include alert tone and repeated alert
tone. Output impedance shall be 45 ohms. Output level shall be 1 watt nominal. Voice switch sensitivity shall be -24 dBm. A
separate unit, the Three Zone Integrated Talkback Page Control, Model V-2003AHF, shall be available with the talkback module
already installed. The axillary DC outputs of the V-2003A shall provide a total of 500mA of -24 VDC for powering one-way
amplified speakers or other accessory devices.
The Battery Back-up Supply, Model VPB-260, shall be available separately. It shall provide a polarized molex
connector compatible with the molex connector on the V-2003A. In the event of power failure, it shall provide power back-up to
the V-2003A and any additional equipment powered by the DC outputs on the V-2003A.
The housing of the unit shall be constructed of gray painted aluminum alloy. The maximum dimensions shall be 7.13"
(18.09 cm) H x 10.0" (25.4 cm) W x 3.0" (7.62 cm) D. Shipping weight shall be approximately 5.25 lbs (2.38 kg).
