  34. I have a customer that has a FXS output port. No other output ports are available from this system and yet we want to connect his telephone system to the paging. Does Valcom have an interface available

What kind of wiring is compatible with Valcom?
Standard telephone wiring (unshielded, Category 3 or 5, twisted pair) is all that you need for wiring com components. Since each Valcom one-way speaker has its own amplifier and volume control, only low level audio signals are transmitted through the wire. Costly shielded wire is not required because crosstalk is not a problem.

How do I connect Valcom Speakers?
Valcom one-way, self-amplified speakers require two pair of twisted telephone wire for connection. Most Valcom interior speakers have screw terminals labeled "T" (TIP), "R" (RING), -24V (negative 24 volts), and GND (GROUND). Some Valcom speakers include a clip-type connector that you can secure and release with your fingers. Other Valcom speakers and horns provide a leader cable with the green and red wires used for tip and ring connections, and the white and black wires used for -24Vdc and ground, respectively. One matched pair (such as white/blue, blue/white) for the tip and ring audio connections and a second matched pair (such as white/orange, orange/white) for the -24Vdc and ground power connections should be used. The cable gauge, type of speaker or horn, and the cable length will determine how many speakers may be connected to any given cable run. Valcom talkback speakers require only one twisted pair which should be no longer than 800 feet.

What if I have great distances between paging areas?
To provide paging throughout areas that are far apart, such as in separate buildings, campus-type environments, or multi-story buildings, it is often convenient to provide a power supply for each location in order to avoid extra long power runs. This solution is true for most types of network installations (not just paging), plus, it helps to preserve the integrity of each "mini-system" location. For transmission of the audio signal only, it is possible to extend the run for miles with V-1094A Page Port Preamp/Expanders.

Back to Top

What if I have more than one floor?
Often, Valcom recommends treating each floor or group of floors as a separate system. This means you should have a separate power supply for each floor. However, you may be able to use existing spare telephone pairs from riser cables for paging signal distribution. This would result in decreased labor and wiring costs.

Back to Top

Is it possible to restrict access to a limited group of users within my company?
Yes. Since Valcom paging equipment is specifically designed for telephone system access, the same programmable phone system features that allow restriction of trunk or C.O. ports can be used to limit access to the paging system.

Back to Top

I have a small key telephone system, and I would like paging now. I may upgrade to a larger key system or PABX later. Will I be able to use my existing Valcom equipment at that time?
Yes! Valcom page control/interfaces are designed for telephone integration. They work with any telephone system's loop start trunk port (C.O. line port), or with dedicated single line telephone sets. The input to Valcom page controls are designed to act like a telephone line. Your Valcom system will be fully compatible with your future key system or PABX.

Back to Top

Can I use Valcom with my 70 volt paging system?
Yes. Say goodbye to costly additional 70 volt amplifiers and heavy gauge cabling. Simply connect a V-1095 70 Volt Expander to the output of the amplifier or to any point on the 70 volt line. Add Valcom one-way speakers and horns and the appropriate power supply. The V-1095 even provides a master volume control for the added speakers and horns and can be used on 25 volt or 100 volt systems as well.

Just how compatible is Valcom?
Valcom peripheral products enhance a host telephone system to provide a full communications system. Although many Valcom products may be used independent of the phone system; however, they are most often connected to a host telephone system. Valcom equipment is designed to connect to virtually any telephone system... 1A2, electronic key, PABX, hybrids, and even Centrex, Plexar and Essex. Among these enhancements are:

◦one-way or talkback paging
◦single or multi-zone paging solution
◦night ring and common audible ringing
◦message and music-on-hold
◦background music
◦priority alert tones
◦code calling
◦door answering devices, and more.

Back to Top

What are dual input speakers?
Valcom offers several styles of dual input speakers: The V-1220 Ceiling Speaker and V-1222 Wall Speaker. Each dual input speaker provides two independent audio inputs with separate volume controls for each. (One volume control is located externally making adjustment very easy and accessible. The second volume control is located internally for less frequent adjustments.) With this feature, the speakers can be used in some very unique applications allowing, for example:

◦separate adjustment of volume of music and volume of voice pages
◦broadcast of different music over every speaker
◦inclusion of a speaker in two different zones
◦dedication of one of the inputs to priority page
◦and much more!

Since the speakers have two audio inputs and also require power, connecting the dual input speaker requires three pair.
