The Three-Zone Integrated Page Control, Model V-2003A shall be a wall or shelf mounted, telephone compatible, threezone, 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 0 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.
