Before You Start Before installing your system, read and understand the safety instructions. Be sure you have all the necessary parts, tools, and test equipment, listed below. 1 Read Important Safety Information on Page 2 2 Check Shipping Container Contents ■ AmpliCenter Unit ■ Power Cord ■ This Installation and Use guide AMPLICENTER D20, D100, D300 INSTALLATION MANUAL AT&T PagePac Plus AmpliCenter Installation and Use POWER CORD Figure 1.
Installation Steps 1 NOTE: If installed next to other equipment, including the PagePac Plus Controller and Zone Expansion Units, leave at least four inches space above and below for proper ventilation. Mount the PagePac Plus AmpliCenter to either the wall, cabinet or a 19" rack. SIDE VIEW AMPLICENTER Figure 2.

NOTE: If more than one speaker cable is routed to the AmpliCenter a connector block is necessary.
5 NOTE: Refer to the Connectivity Chart on page 12 and 13 to determine the page line output type of your telephone system. In most cases, the setting will be Loop Start. You can also check with your telecommunications manager. Set the AmpliCenter Telephone Mode Selection Switch to match the page output type of your telephone system.
The Page VOX (voice activation) sensitivity is turned fully counter-clockwise if the Dry Loop feature is not used. Adjust Music Input level. Clockwise rotation will increase the level. Listen and set to a comfortable level. 4. Using a telephone from the host system, dial the paging extension. Speak into the telephone in a normal manner. Your voice should be heard from all connected speakers.
Troubleshooting 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. Host telephone system failure. 3. Host system page port failure. 4. A hardwire disconnect between host system and PagePac Plus. 5. AmpliCenter switch settings tampered with. 6. Volume low due to DTMF volume level not being set properly.
Controls and Indicators, Terminals and Connectors Figure 10 shows the controls and indicators, terminals and connectors on the rear panel of the AmpliCenter. Table 2 identifies them by function. AMPLICENTER Figure 10. AmpliCenter Controls and Indicators, Terminals and Connectors Table 2. Controls and Indicators, Terminals and Connectors 1. AC Power in: 105 – 125 VAC, 210-250 VAC, 50/60 Hz, (voltage auto-selectable within unit) 2. 0dBm out, an auxiliary output that differs from the main 70.
Connecting Speakers 1 2 3 Locate and mount all speakers in accordance with the floor plan drawing for this installation Connect each speaker to the appropriate Home Run or Speaker-to-speaker wiring scheme as shown on the wiring plan (See Figure 11, below) Test speaker wiring for short circuits Measure the resistance of each home run wire run with an ohmmeter. Any pair indicating a value of less than 15 ohms must be rechecked for possible shorted wiring or speakers. Correct and problems and retest.
Example System Setups Figure 12 illustrates the interconnection between the AmpliCenter and the Controller, if used. Figure 13 illustrates the interconnection of two or more AmpliCenters. AMPLICENTER NOTE: If the AmpliCenter is used with the PagePac Plus Controller, refer to the Controller Installation and Use Guide for detailed instructions.
