What is Paging System

A paging system allows for one-way communication to a large audience. Regardless of the broadcast source, a one-way paging system lets the speaker provide clear, amplified instructions throughout a facility. The paging employee speaks a message into a telephone and that message is then broadcast through a network of speakers. Messages can also be recorded and broadcast at a later time.

 Advantages

1. A network of speakers ensure that a message is communicated to every area of a building simultaneously. It’s also possible to send pages to specific building “zones” if needed.
2. Another key benefit of a paging system is that no dedicated broadcast mechanism is required. An employee can simply pick up the phone, select the paging system and broadcast to the entire building.
3. Backgroungd Music device can be connected to Paging system , Which automatically lower its voume during paging annoucements.
4. In case of emergency , a single message can be delivered to all in seconds.

Paging sound systems are custom designed for distribution centers, dispatch warehouses, industrial storage spaces, loading docks, storehouses, depots, factories, manufacturing plants, airplane hangars and more. You’ll get superb vocal clarity, high powered sound and amazing coverage with world-class commercial distribution audio products .

Facility PA Systems improve internal communication in business environments and provide more efficient solution . It provides audio solutions for offices, factories, dealerships, retail, and warehouses of any size and layout complexity.

Warehouse Pagings requirements depends upon

1. Size of warehouse.
2. Machine or other static noise in warehouse.
3. Height of warehouse
4. Traffic
5. Important Areas to cover
6. How many page zone required ?
7. Auxillary ringer options
8. Particular interval Bells.

 Some of other features are :

1. weather Proof.
2. Emergencies Alert
3. Speakers different wattages
4. Multi-location Paging
5. Zone Paging
6. Talk-Back Feature

Office phone paging systems can provide fast reliable interoffice communications as well as back ground music and white noise for open office areas that are too quite and don’t allow for much conversation privacy.

Designing a small to medium size interoffice phone paging system is not difficult if you keep a few things in mind.

1. The first rule in paging is the more ceiling speakers the better. Having too few speakers will cause you to turn up the volume and paging will be become loud and unclear. So when figuring out how many ceiling speakers you need error on too many than to few.
2. The second thing to consider is the ceiling height. Lower ceiling heights require more ceiling speakers then higher ceilings.

There are several models of ceiling speakers available on this site including standard 8 in ceiling speaker with and without volume control.

By implementing or upgrading a paging system, we can help you:

Increase safety – Make large-scale safety announcements or evacuations and effectively reach everyone in your organization no matter where they are.

Enhance security – Screen visitors and traffic in and out of your organization.

Reach isolated employees – Connect to employees who are working in a factory or manufacturing warehouse, and increase response time with paging systems.

Zone Paging

Zone paging or multi zone system paging equipment allows you to use your telephone paging system to page in single or in multiple user defined zones. Many zone paging controllers allow for up to 99 predefined zones and up to 32 zone groups making it easy for the user to select exactly the zones or groups to page. Several of the zone paging systems also allow for multi zone audio.

For Example

Facility is laid out with 4 zones

Zone 1–Office areas

Zone 2–Engineering area

Zone 3–Production areas

Zone 4–Warehousing/Shipping

Different Phone dial codes can be assigned to different zones..

A person can page in individual zone or multiple zones or all together in all zones.

 Benefits of Paging from Phone

1. Can make announcements from any phone connected to same Phone system.
2. Cam make zone or group announcement.
3. Convenient way of delivering your message.
4. No seperate microphones required or wiring required.
5. No seperate training required for different input devices

Does the phone system have a paging output?

If the answer is yes, then it is typically a simple two-wire connection. Normally all the phonesystems are equipped with this feature ..

But if Answer is no then a TAM-B interface is required. The TAM-B access module is compatible with standard telephone systems and interfaces with the paging system. The TAM-B is capable of either station port or trunk port operation. It interfaces with both PBX station lines and either loop start or ground start trunk ports and often cuts the interface.

How to determine the appropriate amplifier.

• Central-Amplified (70V) Systems:

In this scanario , all the speakers are connected to centralized amplifier and amplifier provides power to speakers

In central-amplified systems, selecting the size of the amplifier is as simple as totaling the speaker power taps and calculate as below

Central-Amplified Speaker System = Power Tap(In watts ) x Quantity =Power

we recommend the selection of an amplifier with 20% more power than the aggregate amount of the speaker taps;

• Self-Amplified (24V) Systems:

In Self amplified speakers , a small amplifier is attached to back of each speaker .

Selecting the proper size power supply for amplified speaker systems has been simplified by assigning a power factor (pf) to each speaker or horn.

Self-Amplified Speaker System = Nominal x Quantity =Total

Note: If the total power (pf) required equals or exceeds the power (pf) of one size power supply, using the next larger supply (or of two supplies) is recommended

Speaker Types

• Ceiling Speakers — typically found in dropped ceilings in officesand stores.

• Wall Baffles — where ceiling height is prohibitive or ceiling speakers are not practical.

• Horns — for outdoors or noisy areas (e.g. warehouse, dock area).

Ceiling Mount :

Because of their cone-shaped spread of sound (referred to as dispersion), ceiling speakers cover more area when the ceiling height is greater. Given this fairly constant dispersion, increasing the speaker volume does not increase area coverage, although it does allow the system to overcome higher ambient noise levels. The area coverage factor remains about the same for all 8” ceiling speakers.

One simple to use rule-of-thumb will allow you to determine roughly the number of speakers to use in any single open area: Space speakers at twice the ceiling height distance.

Wall Baffles :

Wall baffles are used where ceiling height is prohibitive, or where ceiling speakers are not practical. Wall baffles, too, have fairly constant dispersion of sound and the rules for layout and placement are basically the same. However, because they are designed to project forward, square footage coverage ratings are less applicable with wall baffles. Forward coverage and spacing are more important. Whenever possible, it is best to aim all wall baffle speakers in the same direction, as this provides for both better coverage and higher intelligibility.

Fortunately, most spaces have pillars or posts that simplify the mounting and determine the spacing of these types of speakers

Horn Speakers :

Where are they used?

• Outdoors.
• Any weather/environment exposed area, i.e., outdoors, in freezers, and in heat-affected areas.

• Indoors where high ambient noise exists.
• Indoors where large area coverage is necessary and where aesthetics do not require decorative ceiling or wall baffle speakers.

Desired mounting height, barring obstructions, is 15 to 20 feet, with the speakers angled downward towards the listening area.

What is audio Feedback

A deafening squeal coming from the speakers at a concert or other event that causes everyone in the audience to plug their fingers in their ears and shout, “Make it stop!”

Acoustic feedback occurs when the amplified sound from any loudspeaker re-enters the sound system through any open microphone and is amplified again and again and again.

If you speak one word at the microphone at a level of 80 dB and the loudspeaker returns that word to the microphone at 80 dB, then you can go home. The sound system will repeat the sound all day, “chasing its tail” from microphone to loudspeaker.

Feedback Eliminator

Feedback Eliminator is designed to eliminate acoustic feedback and act as a message stacker. When a voice page is made, the message is digitized and saved. Upon completion of the live page, the message is released for broadcast over the speakers.

Features

Multiple Messages Can Be Recorded Simultaneously – Records a Page While Playing a Recorded Page

1. One Unit Eliminate Feedback to All Zones
2. Automatic Consistent Volume Level Even When Recording Voices Vary – Low to High
3. High-Fidelity – Sounds Like a Natural Voice Not Like a Recording
4. LED Indicators For Play, Record, Busy, Power

Worried about missing important calls during non-business hours ?

Night Ringers

Night ringer converts a building’s paging systems into a telephone ringer to alert anyone in the building of an incoming call

Non-business hours are when the least amount of personnel are in a building. With only a few people in the building, they might not be near a phone to hear it ring. This could result in them missing an important phone call.

Night ringer alerts the entire building of an incoming phone call. Night Ringer allows for a tone to be played through a building’s paging system when a call is coming in. Nght Ringer converts most paging systems into an after-hours night bell alert system.

Night Ringer is an efficient way to alert security guards or other personnel of incoming calls during non-business hours.

School bells / Interval bells

The Paging Server has a built in bell scheduler that enables, through a secure web interface, scheduled bells and prerecorded messages to be sent to different multicast zones as well as to legacy analog paging systems.

Perfect for schools, universities, manufacturing or any environment where scheduled bells and zone paging are paramount.

This system is designed for facilities with larger areas or noisy work environments. It’s an ideal solution for factories, warehouses, and other industrial working areas to signaling shift changes, lunch and breaks.
