Telephone Access of a Valcom Page Control/Interface
To provide one-way paging on 1A2, E-Key PABX
Systems, or from one or more dedicated single line telephones, you will need a page control unit, one-way amplified speaker assemblies, and possible a power supply. In most cases, page access will be via a line button for 1A2, a loop trunk port for a PABX or
Electronic Key or via Tip and Ring on a singe line telephone(s).
The control units may be any of the following.
1 zone V-2000A
3 zones w/all call
6 zones w/all call
9 zones w/all call
24 zones w/all call*
*24 zone expansion module ( up to 96 total)
The speakers may be any of those listed in Table 3 or any other Valcom amplified speaker.or horn.
After you have selected the page control/interface and the quantity and type of speakers for your system, use
Tables 1 and 2 to determine system power.
Add up the total Valcom power units (VPU) that will be required. Subtract any power units being provided by page controls featuring integrated power (2000
The remaining number of power units required will determine the quantity and model(s) of power supply required. Reference the next section, "Valcom Power
Valcom Power Units
Each page control/interface, speaker and peripheral device has been assigned a Valcom power unit (VPU) value. Products that provide power, such as the 2000
Series page control/interfaces or power supplies, have power unit values indicated with a plus (+) sign.
Products that consume power have power unit values indicated with a minus (-) sign. Products that neither require nor provide power are indicated by a VPU of zero (0).
After you have chosen the page control interface, speakers and accessories for your application, simply add up all of the Valcom power units [indicated by a minus (-)] for each item that requires power. This total tells you how much power you need. If you have chosen a 2000 Series control/interface, subtract the total power units provided by this controller from your previous total. If you come out even, or you have power left over, you paging system is complete.
However, if you come out with more VPUs required than provided, you will need additional power.
The additional power required will be provided by adding one or more VALCOM power supplies as listed in Table 4.

There are several cases when more than one power supply will be required:
1. When the power required exceed the maximum output of the power supplies available: Add additional supplies as required.
2. In large systems or systems with many horn speakers: Locate separate power supplies near groups of speakers. (Refer to Tables 8 and 10 for guidelines concerning maximum allowable distances for power runs.
3. When the paging system is in several buildings or on several floors of a single building, locate power supply in each building or on each floor being paged.

Block Diagram of Multiple Zones of One-Way Paging
From Multiple Telephone System Page Ports
The Valcom V-1094A, V-2000A or V-2001A control units may be used for page port access to Valcom paging. Each of these units provide one zone of one-way paging. If more than one page port is available a V-1094A, V-2000A or V-2001A may be used on each port for multizone paging. Refer to
Tables 2 and 3. For help in speaker and power supply selection refer to the section titled "1A2, Dedicated
Single Line Set, E-Key, or PABX Paging" .
NOTE: Generally, Valcom dial select multizone page units may not be used on page port output. (The
V-2003A and V-2006A may be used on certain page ports).
Station level Paging
The Valcom V-9940 and V-9970 Station level Page
Adapters may be utilized to provide access to a single or multiple zone paging system via an incoming central office line, Centrex//Essex line or PABX station.
1) Accepts a ringing phone line or station port.
2) Answers that line.
3) Provides line level audio to the paging system.
For a single zone of paging, Valcom One-way
Amplified Speakers may be directly connected to the audio output of the station level page adapter.
Electrically, station level page adapters act like a
The V-9940 and V-9970 are FCC registered for direct connection to the public telephone network, and also carry U.L. 1459 approval. It will ring trip from 70 to
105 VRMS (20 to 30 hertz) ringing voltage.
With a single line telephone, the called party provides the disconnect at the end of the conversation by going
"on hook". A station level page adapter, on the other hand, has no way of "knowing" when the calling party has finished speaking. This unit has to sense line conditions in order to determine when it is time to disconnect.
With the V-9940 and V-9970, this line condition may be quiet line sensing, a strict "time out" (disconnects after a selected period of time) or open loop disconnect of at least 150 milliseconds. Open loop is a service provided by the central telephone office and involves actually disconnecting the telephone line from the C.
O. for a brief instant. In some cases the "quiet line" may also be programmed via the PABX. "Quiet line" implies that the PABX will not return any tones (dial tone, busy tone, reorder tone . . . etc.) to the called station at the completion of the station to station call.
The telephone system may be tested for a "no returned tones" status with your test set; have someone call you on a station and then ask them to hang up . . . if you do not hear any tones, or if there is a delay of at least 10 seconds before you hear any tones, then the "quiet line" (i.e. audio sense time-out) may be used.
Ground start telephone lines are a good choice for use with the V-9940 since a ground start line will not return dial tone until a ground is applied to the ring lead.
Additionally, the V-9970 recognizes re-order tones and dial tone as disconnect signals.
The V-9940 can be used alone, or can provide access to Valcom multi-zone and talkback page control units.
The V-9970 may be used to access the V-2003A and
V-2006A multi-zone control units only. The V-9970 is not compatible with any talkback page control units.

These instructions will provide a basic understanding for wiring Valcom one-way paging equipment and connecting it to a telephone system.
For specific wiring information, consult the installation practice enclosed with the actual equipment being used.
Do not locate Valcom equipment or cabling within 18" of a power supply, electrical panel, or any equipment that generates electrical noise.
The control equipment should be installed at the main distribution frame with the telephone system common equipment.
The V-1109RTVA, may be mounted to the backboard, in a 7" KTU rack or mounting frames. A 66-type and
25-pair pigtail with female amphenol connector are required for connections to these units if the mounting frames are not used. Other control units are wall mount units with connections via either screw terminals, integrated punch down block, or a user supplied 66-type block.
Ceiling Speakers: The area covered by a ceiling speaker depends on the height of the ceiling. Refer to Table 5 for speaker coverage.
Wall Speakers: A wall speaker will cover up to
600 square feet. Wall speakers should be spaced 20 feet apart.
Good quality paging will be heard up to 30 ft. in front of the speaker.
Corridor Speakers: Corridor speakers should be mounted 8 to 12 feet high and spaced 30 to 40 feet apart.
Refer to Table 6 for horn speaker coverage. The first figure given is the side to side distance between the speakers. It is also the distance in front of the speaker that you can expect to hear a good quality page. The second figure given is the area being covered in square feet.
Track Style Speakers:
The 1 watt version will cover an area up to 600 sq. feet. These speakers should be spaced approximately 20 feet apart.
Good quality page audio will be heard up to 30 feet in front of the speaker.
The 5 watt version will cover up to 3,600 sq. feet. Depending upon the height of the installed speaker, good quality paging will be heard up to 60 ft. in front of the speaker.
The area covered by a pendant speaker is determined by the mounting height. Refer to Table
5 for speaker coverage.

15 Watt 30 Watt
Very Noisy: Greater than 90dB. This would include areas where talking to another person is very difficult.
Workers may be required to wear earplugs.
In areas the sound level exceeds 100dB, consideration should be given to using a code call unit (V-9923B) for tone signaling instead of using voice paging.
In extreme ambient noise, it is generally easier to identify a tone code than to discern speech.
Reverberant Areas - To increase the intelligibility of paging in reverberant areas, horns should be mounted closer to the people being paged, in effect, mounted at a lower height, closer together and angled towards the floor.
All Valcom one-way amplified speakers require 2 pairs to operate. Standard CAT 3/5/5E/6 telecom/ data cable may be used. Existing telephone wire and feed cables may also be used. Refer to Tables 7 and 8 when planning a job.
Audio pair: The number of speakers looped on the audio pair is not critical unless you have a very large job. Table 7 gives guidelines for the number of speakers per audio run.
Power Pair: The cable runs specified in Table 8 are very important and MUST be followed for proper operation of the one-way paging speakers.

Noise Level Definitions
Quiet: 50-65dB. This would include areas such as waiting rooms or doctors' examination rooms.
Moderate: 65-80dB. This includes areas such as warehouses, shipping areas, or light manufacturing.
Noisy: 80-90dB. This includes machine shops or heavy manufacturing.

Bridges and Backboxes
Ceiling speaker bridges provide support to prevent ceiling tile from sagging from the weight of the speaker. They are designed for use with standard 2' wide ceiling tiles and distribute the weight of the speaker assembly across the tile and onto the tile support grid.
Ceiling speaker backboxes provide an acoustic enclosure behind the speaker for better sound quality.
They also protect the speaker from debris in the ceiling and meet most local fire codes for use in air plenum return ceilings. See Table 9 for Speaker and
Master volume controls are located on most Valcom page control units. Each one-way speaker assembly also has its own volume control. When installing a system, set the master control to 1/2 and all speaker and horn volume controls to 1/2 volume. After powering up the system, adjust the individual speakers to the desired level.
The master control may then be used to change the volume of the entire system. If background music is being supplied, the background music level should be adjusted last. To provide volume control to a certain room or area, V-1092 Wall Mount Volume Controls may be added to a zone, or to a section of a zone.
Each Valcom page control unit contains the circuitry required to interface with a telephone system, plus a preamplifier circuit, and in some cases dial select circuitry and/or provisions for background music switching. Each one-way amplified speaker assembly contains a speaker, amplifier, and volume control in a suitable baffle or housing. The speakers and control units require a -24VDC power supply (-48VDC for the
V-1038) to operate.
Connections from the control unit to the telephone system are described in detail in the manual that is shipped with the control unit.
The audio pair from the control unit to the speakers may be looped (speakers wired in parallel) between all speakers in a zone (See Table 7). A second pair must be run to each speaker to supply the DC voltage required for operation (See Table 11). Standard 22 or
24AWG telephone cable may be used for the speakers.
When accessing a single zone control unit from the telephone system, you will immediately be connected to the speakers and allowed to page.
When accessing a multizone control unit from the telephone system, you will receive Valcom dial tone from the Valcom unit. After dialing the code for the zone desired, you will be connected to that group of speakers and allowed to page. All Valcom control units automatically release when you hang up the telephone.

Automatic Volume Control
The V-9933A Noise Sensing Volume Control monitors the noise level fluctuations in an area by utilizing a built-in microphone. When a page is made, the
V-9933A electronically locks onto the last noise level sampled and automatically adjust the volume of up to
150 Valcom One-Way Self-Amplified Speakers in order to compensate for the current ambient noise level, thus eliminating the need for personnel to manually adjust the paging speakers. The V-9933A should be mounted in the area that experiences the fluctuating noise. If a single zone contains areas of independently fluctuating noise levels, multiple V-
9933A units may be used (one per area).
• Each Noise Sensing Volume Control, V-9933A, can control up to 150 amplified speakers or horns in a single zone.
• Multiple Noise Sensing Volume Controls, V-
9933A, can be used on the same zone if desired.
• V-9933A can be connected to a zone output of any
Valcom One-Way Page Control/Interface or
Station Level Page Control.
• Not for use with background music without additional equipment.
The V-9934 Remote Microphone may be used with the V-9933A Noise Sensing Volume Control.
• V-9934 is a self-contained microphone and preamp.
• No power supply is required for V-9934
• Up to four v-9934 units may be paralleled on one
• Each V-9934 may be on a 1000’ wire run.
Stacking Feedback Eliminator
The V-9964, Stacking Feedback Eliminator, is designed to prevent paging system feedback. When a page is made into a zone, the V-9964 records the page into digital memory. Upon completion of the live page, the message is released to play over the zone of speakers. Since the paging party has hung up the telephone or released the microphone, offensive feedback cannot occur.
• Each Stacking Feedback Eliminator, V-9964, can control up to 150 amplified speakers or horns in a single zone.
• Multiple Stacking Feedback Eliminators, V-9964, can be used on multiple zone page controls.
• The V-9964 can be connected to a zone output of any Valcom One-Way Page Control/Interface or
Station Level Page Control.
ENHANCEMENT TO EXISTING
25/70/100 VOLT PAGING
Using a Valcom Page Control/Interface with a Central Amplifier
Typically a zone from a one-way control unit may be directly connected to a high power amplifier to allow access to existing paging equipment. In certain cases capacitors or a resistor network may be required to interface the Valcom equipment to the amplifier.
Contact Valcom Technical Support if trouble is encountered.
NOTE: Not all Valcom page control units have control leads available for amplifier control.
Use Valcom One-Way Self-Amplified Speakers to expand a 25/70/100V audio zone.
It is cost effective to expand a centrally amplified paging system with Valcom distributed amplified speakers. In many instances expanding a centrally amplified paging system involves replacement of the expensive central amplifier with a larger one in order to provide the additional power that the speakers or horns require.
This also involves additional labor in re-balancing the system. Adding high voltage type speakers to an existing amplifier where the load is not configured properly will cause distortion or premature system failure, again requiring replacement of the central amplifier. By using Valcom distributed amplified speakers to expand the system, almost unlimited growth is possible, without loading down the existing amplifier.
ADVANTAGES OF DISTRIBUTED AMPLIFIED SYSTEMS
• Low voltage, therefore existing telephone cable (Class 2 wiring) can be used to eliminate costly outside plant or indoor conduit.
• Low voltage operation means much less power dissipation (heat), therefore the longevity of the paging equipment is increased dramatically.
• Multizone capability of 96 zones from a single trunk port. (Up to 576 Zones with All Call with multiple systems connected for Global All Call – Call Valcom Technical Support for assistance)
• Talkback, one-way or combination systems are easy to configure.
• Individual volume controls built-in to each one-way speaker for volume adjustment after system is installed.
• It is cost-effective to install one telephone cable versus installing both telephone cable and 70 volt shielded paging cable.
• Unlimited one-way speaker expansion since each speaker is self-amplified.
• Jobs requiring explosion-proof systems are easily accommodated.
• Amplified one-way speakers can interface 70 volt systems without changing or adding central amplifier.
• Many localities require conduit for "high voltage" (Class 1) conductors, this is rarely a necessity with a distributed amplified system.
• The rated output of a distributed amplified paging speaker or horn is always available due to the fact that the actual audio signal amplification is accomplished on an individual basis. In a 70 volt system, the rated output is only available if the central amplifier is actually providing a full 70 volts to the speaker or horn and the audio signal line losses are negligible.
• Background music is unaffected in zones that are not currently being paged.
