About This Guide The PagePac Plus AmpliCenter Installation and Use Manual explains the features of the AmpliCenter, how to install and configure the AmpliCenter, and interface to a communication system and other auxiliary equipment. It is intended that PagePac Plus be installed by a trained telephone, audio, or electrical installer with basic electronic knowledge. PagePac Plus conforms to common installation practices and preferences found within the Telcom Electrical and Commercial Sound installers manual.
Installation Steps 1. Mount the PagePac Plus AmpliCenter to either the wall, cabinet or a rack. 2. Pull cables. 3. Hookup cabling to AmpliCenter and auxiliary equipment. (Refer to Example Setups in section 3.) Use stick-on labels to identify the AmpliCenter/zone (i.e., cafeteria - zone 1). NOTE: The numbers in these steps match the numbers in figure 1-1. 4. Set the AmpliCenter Telephone Mode Selection Switch to match the host telephone system and make connection. 5. Install power cord and plug into outlet.
Connectivity Chart The Connectivity chart gives the trunk interface requirements for the host systems listed. This information is then used to set the telephone mode function switch on the PagePac Plus AmpliCenter. Table 1-1.

This section provides complete instructions for mounting the PagePac Plus AmpliCenter on a wall or in a standard EIA 19" cabinet or equipment rack. It also illustrates all interface requirements to (optional) PagePac Plus Controller, telephone systems, music source, speakers, auxiliary equipment, and any control inputs or outputs. Important Safety Information Always follow these basic safety precautions when using the system: 1. Read and understand all instructions. 2.
Example System Setup Amplicenter Interface with Controller This example illustrated in figure 3-1 gives you a quick overview to the interconnection between the AmpliCenter and the PagePac Controller. See the PagePac Plus Controller Installation and Use manual for details on setting up any of these configurations: A traditional 70 volt installation The 70v AmpliCenter Audio Output Is Routed Via The Pagepac Plus Controller to paging zones.

Mounting PagePac Plus AmpliCenter NOTE: Figure 3-3 illustrates a wall mounted configuration. Figure 3-4 illustrates a rack mounted arrangement. The AmpliCenter must be securely wall mounted or installed in a standard 19" EIA cabinet or free-standing equipment rack (Wall mount wood screws not provided). Tools Required The following tools are required for the installation of the system hardware and cabling.

Connecting Speakers Using common industry standard procedures or accepted practices of AT&T for telephone equipment, mount speakers and adjust speaker top for each paging zone and run the appropriate cable for 70 volt speaker systems. Use class 2 wiring, and comply with any local safety codes. The speakers are wired to the AmpliCenter using either of two methods (figure 3-5).
Telephone System Interface The AmpliCenter, when used without a PagePac Plus Controller, connects directly to your facility telephone system for paging. Figure 3-6 shows this interconnection. Be sure the Telephone Mode Switch on the rear of the AmpliCenter is set to the type of telephone system you have (see next paragraph). When used with a PagePac Plus Controller, the AmpliCenter receives its telephone paging input from the controller. Figure 3-6 illustrates this interface, as well.
The Dry Loop 600 Ohm is a four wire interface consisting of a dry audio pair with a 600 ohm impedance and a control pair. The page input is activated when the control pair receives a contact closure from the host equipment, connecting C1 to ground. The Dry Loop page input can also be activated by the presence of page input audio signals that exceed a set threshold. This threshold is set by the page VOX adjustment; clockwise rotation lowers the threshold and makes it more sensitive.

Music Source Interface Music Input To provide background music for your paging system, a music source can be connected to your AmpIiCenter at the 10-position connector on the rear. The audio source can be a CD player, AM, FM, or commercial radio, tape player, or other audio device. Since most music sources are stereo, left and right channel inputs are combined in the AmpliCenter. Monophonic sources can be connected to either left or right input with the other not connected.
System Testing With the zone wired and connected to the AmpliCenter, testing may begin. CAUTION: Be careful not to short out any audio output contacts during this procedure as the AmpliCenter may go into overload as indicated by the overload LED. A distorted or inaudible page will result. Apply AC Power Power to the PagePac AmpliCenter is supplied through a single power cord connected to a grounded outlet. There is no power switch.
7. The Paging output is limited to a nominal 70 Volts rms by the ALC. In a properly designed system, sound loudness is normally adjusted by selection of appropriate speakers and their individual tap settings for a 70 Volt input. However, circumstances such as a long term change in ambient noise may call for reducing the loudness of all speakers en-mass. This output level can be attenuated by an overall AmpliCenter output level control setting.

Your PagePac Plus system is designed to provide trouble-free performance without any special maintenance procedures. To reduce the risk of accidental damage: ■ Keep the system modules in an area free of dust, smoke, and moisture, and do not block their air vents. ■ Keep the rear of the modules neat. Strap down cable runs and avoid excess loose wires and debris that could cause short circuits.
Power Failure Operation The PagePac Plus AmpliCenter will operate with the host telephone system in the event of a power failure if both are connected to an uninterruptable power supply (UPS). If the host system is Centrex, no local power is required for the telephone system, though the AmpliCenter requires AC power. Common Problems Some common problems encountered when the paging system is not operating are described below. Check each item in the order listed. 1. No AC power to AmpliCenter 2.
Table 4-1. Troubleshooting Corrective Action Problem Page extension does not answer No power to AmpliCenter. Host system not passing call through to AmpliCenter. Telephone Mode Selection Switch not set correctly for host telephone system. Ground start - Tip and Ring reversed. Page extension answers, but page is not heard Audio signal not reaching speakers. Check wiring at controller. Verify Page Accessed LED is on. Low volume. Adjust music output levels on AmpliCenter.
