Model V-2924A, V-2925A, V-2926, V-2928
The proposed system is an expandable, multi-zone intercom/paging/signaling/program distribution sound
system. The system is a combination of zone and feature cards, connected and housed in a central location
and provides for page priority of emergency messages from any phone. System provides background music
and tone distribution if required. The expandable intercom/paging system, V-2924A, shall provide telephone
accessed two-way voice intercom and paging utilizing 45-ohm talkback and one-way paging with self-amplified
paging loudspeakers. The system shall provide 24 station ports of paging/intercom with handsfree talkback,
one-way group call and all call. Using the V-2924A administrative port, the system shall provide for call
origination from designated telephone(s) to any speaker location and from any of the speaker locations to

music/message input with an input impedance of 10k ohms. The music/message input shall have a frequency
response of 50 Hz to 17 kHz +/- 3 dB with less than 1.0% distortion and greater than -70 dB signal to noise. The
one way page amplifiers shall have a frequency response of 150 Hz to 7.5 kHz +/- 3 dB with distortion less than
1.0 % and signal to noise greater than -70dB. The unit shall provide the following additional inputs: inhibit
(ground activated), -10 dBm/10k ohm evacuation tone input, a -10 dBm/10k ohm time tone input and a universal
night answer activation input. The integrated ring supply shall provide 90 Vac, 30 Hz signal in the following
optional ring patterns: 2 sec on, 4 sec off ; 1 sec on, 4 sec off; double ring burst. The following auxiliary output
contacts shall be provided: remote signaling closure (follows ring pattern), 4 momentary contact closures to
operate electric door locks.
The intercom shall operate on 120Vac/60 Hz or 240Vac/50 Hz. When using the V-2926 Option Card, the
system shall also provide the following features: User page groups programmable for dial code selection of
multiple pre-defined page groups, time sync relay, enhanced caller ID, flexible architectural numbering, EEROM
data storage, and internal real time clock. Additionally when using the V-2928 Option Card, the system will
provide automatic timekeeping and audio control functions using event scheduling.
The V-2924A system programming tool shall be a Windows 95, 98, NT, 2000 and XP based software tool
designed exclusively for the system and provided with either the V-2926 or V-2928 optional enhancement cards.
