Planning a Paging System–

It’s More Than a Bunch of Speakers

The most common complaint we hear about paging

systems is that employees either can’t hear their

page, or even if they can hear them they simply

can’t understand them. Whether the situation

occurs in an ofﬁce, manufacturing facility, or retail

environment, the result is almost always the same.

The paging employee has to make a series of repeat

pages, and that person’s frustration becomes more

apparent with each additional page.

Poorly planned paging systems are inefﬁcient, add

unnecessary employee stress, and worst of all,

result in lost sales. After all, whether the customer

is in a store waiting for the paged person, or on the

phone, they’ll walk away or hang up if they don’t

feel they’re being attended to in a prompt fashion.

Planning an efﬁcient paging system is not difﬁcult.

You do not have to be an expert sound engineer

to spot potential trouble spots and come up with

solutions. But you do have to take the time to

analyze the project layout, predicting the most

likely ambient sound levels, and determining the

most likely paging patterns.

Once you have those characteristics in mind, you

can then determine the number and types of

speakers to use. In addition to calculating speaker

counts and placement locations, you should also

determine which areas require adjustable volume

controls, and whether those volume controls are

speaker or wall mounted.

Next, you can calculate ampliﬁer wattage needs.

There is no such thing as a “one-size-ﬁts-all”

paging ampliﬁer. For example, you may choose a

standard 30 watt ampliﬁer to cover the majority of

the facility, but add extra ampliﬁers for noisy areas

such as factory production areas, warehouses, or

outside lots.

Before you settle on ampliﬁer choices, make sure

you’ve properly considered zoning the system. It’s

true that zoning adds cost to the system, but the

feedback we hear from our customers and installers

is that the cost is well worth it. Zoning minimizes

interruptions to business areas that have no need

to hear all pages. Imagine how distracting it is to

accounting personnel to hear every salesperson’s

page.

Finally, make sure you consider the advantages of

feedback eliminators and page repeaters. Surveys

show that most paged parties miss their ﬁrst page

simply because they weren’t paying attention

until they heard a portion of their name. By that

time they have most likely missed which line they

are supposed to pick up, or where they are to

report to. With a page repeater in the system, the

paging party makes the page one time. The page

repeater records the page, time shifts it to eliminate

feedback, and then plays the page once or twice,

depending on programming. The result is more

prompt attention to pages.

The Rule of Thumb Spacing Model

Sound coverage per speaker is directly related to

ceiling height. The taller the ceiling, the more the

sound spreads. Think of how a ﬂood light mounted

higher up illuminates a larger area. The rule of

thumb model states that you place speakers apart

by twice the height of the ceiling. (See ﬁgures to

right)

For example, if you’re working with 8’ ceilings,

place speakers every 16 feet. In this example each

2 speakers cover 256 square feet of ceiling (16 x

16).

Just like lighting, speakers perform best when they

are in the line-of-sight to the listener. Do not mount

speakers next to large beams or partial walls that

would obstruct the sound.

Consider the Reﬂection Issue

Reﬂected light is often softer and more pleasing

than light directly from the source. Unless, of

course, the light is being reﬂected off of glossy

surfaces, in which case it causes glare. The same

is true of sound. If your installation has hard ﬂoors

(vinyl, concrete, hardwood, etc.) and other “hard”

features such as metal benches, large industrial

equipment, etc., you have to be especially careful

to avoid “glare” or sound reﬂection. These surfaces

tend to distort sound, making pages unintelligible.

If the same application has high ceilings, planning

gets a bit more complicated because the listener

also hears reverberation.

The human aural system can easily integrate

sounds heard within 30 milliseconds of each other.

Reverberation causes more than a 30 millisecond

delay and the listener is bombarded with distortion

and “dual messaging.”

In these applications you must modify the rule of

thumb spacing model and consider a minimum or

full overlap spacing pattern. (See next page)
