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
designated telephone(s). The V-2925A expansion units shall provide for expansion in 24 station increments with
a maximum capacity of 96 stations. Additionally, provisions shall be made for up to six fully expanded 96 zone
systems to be interconnected to allow one-way global all call and one-way global priority pages of up to 576
stations. The V-2926 enhanced feature option card provides Windows 95, 98, NT, 2000 and XP programming
tool, enhanced caller ID integration and architectural room dialing of station ports. It also features remote
maintenance and diagnostics to facilitate optional maintenance from off site service location via modem. The
V-2928 Tone/EventScheduling software option shall provide added features to automatically distribute tones
and messages via user defined schedules.
The intercom shall be accessible from a C.O. line position of a key system, loop start (or caller ID) trunk
port of PBX, dedicated single line telephone set and STA outputs connect to 45 ohm talkback speakers
equipped with optional call buttons. The system shall provide the following features; “Meet-Me” and “Follow Me”
capability, call queue, two or three digit numbering plan, dial tone, ringback tone, alert tone, repeated alert tone,
the ability to operate electric door locks, inhibit input, evacuation tone input, time tone input, night ring input,
enhanced caller ID, SMDR printer port, and shall be compatible with the Valcom VPB-260 battery backup set.
The system shall provide an override input for system-wide emergency one-way announcements. With the V-
2926 Option Card, stations shall be dial selectable via flexible two, three, or four digit programmable user
numbers.
The intercom shall provide a tip and ring input impedance of 600 ohms with a nominal level of -10 dBm. The
speaker output impedance shall be 45 ohms. Each port may be strapped to provide a one way paging audio
signal to drive groups of self-amplified paging loudspeakers. The unit shall provide a line level background
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.
The V-2924A Control Unit dimensions shall be 17.5” (44.45 cm) H x 10.3” (26.16 cm) W x 3.06” (7.77 cm)
D. The shipping weight shall be 17.5 lbs. (7.88 kg).
The V-2925A Expansion Unit dimensions shall be 17.5” (44.45 cm) H x 8.37” (21.26 cm) W x 3.06” (7.77
cm) D. The shipping weight shall be 13.5 lbs. (6.08 kg)
The V-2926 and V-2928 Option Boards and Windows software dimension shall be 5.3” (13.46 cm) L x 3.0”
(7.62 cm) W x 1.1” (2.79 cm) D. The shipping weight shall be 1.3 lbs. (.59 kg).
