Paging and Sound Systems Overview

Before I.T.I. was an Internet service provider, before I.T.I. was a data network integrator, before I.T.I. was the leading telephone equipment vendor in Michigan known as "The Other Phone Company", I.T.I. was an Executone sound equipment dealer. We're talking roots here -that was over 37 years ago. We've come a long way since then but our expertise in sound system design and installation remains.

Paging systems offer many benefits including: increased productivity, professional image, better customer service through greater accessibility to people, increased revenue with fewer lost orders, and reduced long-distance call backs.  Background music increases productivity (major background music suppliers claim 15% rise) and increases conversation privacy.

Telephone paging systems seem pretty simple at first glance. You connect a paging amplifier to your telephone system and to a bunch of speakers, you press a button on your telephone and voilà, you're paging. In reality, there is a lot of design expertise involved in creating a good paging system. After all, you don't want a system that you can't hear in one room but then "blasts" you when you're in another. Nor do you want a system that is so muddled it sounds like the teacher in the Charlie Brown specials, "Whaa whhaa, wha, wha, wha, whaaaa".

Whether your environment is as quiet as an empty library or as noisy as a large stamping factory, I.T.I. can design a system that will have clean, clear sound. Our paging system designs take into consideration: ambient and peak noise sound pressure measurements, room dimensions, ceiling height, and your specific design and integration goals.

Telephone Systems Supported

There are several ways to interconnect telephone and paging systems. The better telephone systems have external paging ports built in while others require a converter for an analog trunk, an analog station, or a digital station interface. All telephone systems that are sold by I.T.I have one or more direct paging ports, including:

•  Samsung iDCS Family
•  Samsung DCS Family
•  Tadiran Coral Family
•  Sprint IPx Family

We can provide custom integration with your existing equipment such as public address systems, two-way radios, intercom systems, alarm systems, and more.

Important functionality to consider and questions to ask when selecting a telephone system and paging system include:

Does background music cease playing when someone is paging?
Can telephone speakers and paging speakers be accessed at the same time?
Can different zones of speakers be defined so warehouse paging doesn't unnecessarily interrupt the front office?
Can paging be accomplished over a network to a remote site?
Does the telephone system have page queues for each user so pages are kept short and don't have to be repeated?
Does the paging system have an anti-feedback feature to prevent audio feedback for telephones near horns?
Does the paging system support "talk back" so a person being paged can respond hands free?
Does the paging system support telephone night ringing?
Does the paging system support connection to the fire alarm or other emergency systems?

TPU-15A Telephone Paging Amplifier

Bogen TPU-15A Datasheet (pdf)
Specifications

Features
15 Watts
Inputs for telephone line and background music
Automatic level control circuit
Signal-activated music muting circuit

Overview
The TPU-15A is a 15-watt, wall-mounting amplifier specifically designed for telephone paging applications. It incorporates state-of-the-art electronics to provide voice-activated muting of music when paging, completely eliminating the need for manual activation switches or external relays. In addition, the unit has a night-ringer feature that can be used to alert personnel of an incoming call during non-business hours.

The paging channel features automatic level control to maintain a constant output even when persons with varying voice levels and paging techniques have access to the system.

Inputs are provided for a 600 W balanced telephone line, a background music source and dry contacts which, when closed, trigger the night ringer. Screwdriver-adjustable controls are provided for page, night ringer and music volume. A tone control, LED overload indicator, Lo-cut filter and push-to-reset circuit breaker are also provided.

Output terminals offer a choice of 25 volts, 70 volts or 8 W for connection of various types of loudspeakers

TPU-35B and TPU-100B Telephone Paging Amplifiers

Bogen TPU-35B and TPU-100B Datasheet (pdf)
Specifications

Features
35 Watts TPU-35B
100 Watts TPU-100B
Inputs for telephone line, microphone, and background music
Built-in Night Ringer
Voice-activated, variable level, music muting/fading circuit
Automatic level control circuit

Overview
The TPU-B Series are state-of-the-art telephone paging amplifiers.

The paging channel is signal-activated and automatically mutes background music when paging from a telephone. The muting level of music during a page is adjustable, and the music gradually returns to its normal level after a page. The paging channel also has a VOX sensitivity adjustment to eliminate transmission of background noise, and features automatic output leveling to maintain constant output.

The TPU-B series incorporates the Aphex® Aural Exciter circuit to regenerate the harmonics lost during the amplification process, resulting in increased presence and clarity, increased intelligibility, greater perceived loudness (with no increase in power), and reduced listener fatigue.

Input terminals are furnished for a telephone line and Lo-Z balanced microphone. Terminals are provided for music mute (during microphone page), and for activation of the night ringer. Jacks are also provided to bridge two TPU-B amplifiers to double the number of inputs and outputs.

Balanced or unbalanced outputs are available for 16 W, 25V, 25VCT, 70V, and 100V speaker lines. Provision is included to feed a 600 W telephone line, LO-Z input or balanced Mic input of another amplifier, using an accessory transformer (Model WMT-1A). Front panel controls are provided to set telephone and mic page volume, music volume, night ringer volume, VOX sensitivity, music mute level, bass and treble levels, ALC, VOX sensitivity and Aphex effect.

TBA-15 Talkback Amplifier

Bogen TBA-15 Datasheet (pdf)
Specifications

Features
15 watts
Two way conversation between telephone and loudspeakers
Hands-free talkback from speakers
Signal-activated music muting circuit

Overview
The TBA-15 talkback amplifier automatically senses and switches the direction of conversation between a telephone and remote loudspeakers. Control of speech direction is maintained at the telephone. Screwdriver-adjustable controls are provided to adjust switching sensitivity, switching delay time and loudspeaker and handset volume. The amplifier includes a 600 ohm transformer-coupled telephone line input, 25V/70V constant-voltage outputs and mute terminals to facilitate unidirectional paging. The amplifier is easily installed on a backboard or in standard 19” equipment rack.

Viking Digital Feedback Eliminator FBI-1A

Features
High quality digital message storage
Paging and alert tone volume adjustments
Uses paging or trunk ports
Cancel page feature
Selectable pre and post-page alert tones

Overview
Even the best paging systems can experience feedback. Now you can eliminate annoying feedback over your paging speakers with the FBI-1A digital anti-feedback paging interface. The FBI-1A utilizes state of the art digital recording technology to record the "live" page from a phone system's paging port output or unused trunk port. The FBI-1A then immediately plays back the recorded page once or twice (selectable) over the paging system.

Pages up to 16 seconds (expandable to 60 seconds) can be stored and the FBI-1A automatically adjusts to the page length for faster processing. In addition, the FBI-1A can be programmed to provide pre-page and post-page alert tones.

Eliminates feedback in warehouses, factories, stores, hotels, airports, and other large noisy areas.
