Introduction
This document describes the Avaya 10-watt Telephone Paging Amplifier.This is a fullfeatured, wall-mounted amplifier that provides inputs for dry loop 600-ohm
telephone page signal and background music source. A set of control inputs allow
an external contact closure to mute background music and open the telephone page
channel. Background music mute level during page is adjustable and the music slowly
fades back in after the page is completed. An automatic level control system limits
the output level of the telephone page channel so that differences in the volume of
the paging party's voice will be less noticeable. A tone control is provided for
optimizing tonal balance for the specific installation. This amplifier includes a built-in
night bell that can be triggered by an external contact closure. The night bell mutes
the background music, but not pages.
Package Contents
* Telephone Paging Amplifier unit
* 2 mounting screws
* Installation and Use Manual
Before You Start
Review the contents of the box. Read through this entire manual to understand how
to install and operate this product.
NOTE: Use minimum 22 AWG shielded, twisted pair wire for your speaker runs.

Installation
Mounting
The amplifier is designed for wall mount applications. The 10-watt amplifier weighs
4 lb.
NOTE: The amplifier will produce heat during operation which will rise and may
cause problems for temperature-sensitive equipment mounted above it. Mount the
amplifier near the top of the backboard so that no other equipment will be above it.
If this is not possible, then allow at least 12" between the top of the amplifier and
the bottom of any equipment positioned above it. Also allow at least 4" between the
bottom of the amplifier and any equipment below it to allow for adequate air
circulation. In addition, because the unit itself gets hot, avoid touching it during
operation.
Wall Mounting
To wall mount this unit, use the two 5/8” pan head screws with nylon washers
provided.The screws should protrude approximately ¼" from the surface of the
backboard. Lift the amplifier and place it over the two screws using the keyhole
slots in the flanges at the sides of the amplifier.The screws should engage the
keyhole slots. Once in the keyhole slots, tighten the screws to secure the amplifier.
Wiring Connections
IMPORTANT: Before making any connections or wiring changes to the amplifier
or any equipment connected to the amplifier, make sure that the amplifier is NOT
plugged into an AC outlet.
NOTE: The amplifier does not have a power switch, so it must be unplugged in
order to turn the power off.
Input Wiring
TEL Input and Control Pair
All signal input and control wiring is made to the terminal strip on the front of the
unit.
The telephone input is a 600-ohm, dry loop, balanced input available at the T and R
terminals. It is controlled by a dry contact closure that is made between the control
terminals labeled TEL CONT and GND. Shorting these terminals together will mute
the background music input and open the Tel page channel (see Figure 2).
NOTE: In instances where the amplifier is to be placed permanently in the Tel page
mode, a wire jumper must be installed between the TEL CONT and GND terminals.

Tel Input to Universal Coupler
After properly connecting your Universal Coupler (909) to your Auxiliary Trunk
port, set your switches as follows: C1/C2 to C2; Rocker Switch 3 closed; and all
others open. Coming out of the J2 Jack of the Coupler, connect the blue/white pair
to the amplifier’s T and R terminals.
Music Input
A pair of terminals are provided for the connection of a background music source.
Use a pair of wires (not included) to make this connection. This is a mono input and
requires that the output of stereo sources be converted to mono by using a Yadapter (not included). Use a LUWMT1A (COM Code: 405891680) to balance the
music input, if necessary, to reduce hum/noise from a grounded music source.
Night Bell Connection
An external contact closure activates the night bell function of the amplifier. When
using an external contact closure, connect the closure pair across the Night Bell
terminal and GND. The night ringer follows the cadence of the activating signal.
CAUTION: Do not apply a high voltage (90-105V AC, 20-30Hz) ring signal to the
Night Bell terminals. Use a dry contact closure only.

Output Wiring
All output wiring connections are made to the terminal strip located on the left side
of the LU10WAMP.
IMPORTANT: Before making any connections or wiring changes to the amplifier
or any equipment connected to the amplifier, make sure that the amplifier is NOT
plugged into an AC outlet.
NOTE: The amplifier does not have a power switch, so it must be unplugged in
order to turn the power off.
Speaker Connection
70-volt speaker connections are made between the 70V and COM terminals on the
output terminal strip (see Figure 3). Use minimum 22 AWG shielded, twisted pair
cable. Connect the shield of the cable to the terminal strip.
NOTE: The amplifier output terminal strip also includes terminals for 8-ohm and
25V speaker connections. These are provided for special applications and are
generally not used.

Operation
IMPORTANT: Before plugging the amplifier into an AC outlet, turn all volume
controls to their full counterclockwise positions and all other controls to their
reference position.
Indicator
PEAK LEVEL
The PEAK LEVEL LED illuminates whenever the speaker output signal level
approaches its maximum level. This indicator is used when setting volume levels.
Maximum output level is achieved when the PEAK LEVEL indicator flashes
intermittently on loud peaks of the input signal. If the indicator illuminates steadily,
the output signal volume is set too high and distortion is occurring. Decrease the
volume control for the appropriate input until the indicator flashes only
intermittently.
Controls
PAGE VOLUME
This control adjusts the level of the telephone page output. A reference level setting
position is provided with this control. When set to this position, the output level of
the page should be optimally loud without distortion. Further adjustment can be
made using the PEAK LEVEL indicator, as described above.
MUSIC VOLUME
This control adjusts the level of the background music output. No reference level
setting position is provided. The background music level should be set to an
acceptable level without overdriving the system. When adjusting this level, use the
PEAK LEVEL indicator, as described above.
NIGHT BELL
This control adjusts the level of the night bell tone output. No reference level setting
position is provided. The night bell level should be set to the customer's satisfaction.
When adjusting this level, the PEAK LEVEL indicator should be used to ensure that
the amplifier signal is not distorted.
LO-CUT SWITCH
Set the LO-CUT switch to the LO-CUT position for optimum speech reproduction
and to reduce unnecessary low frequencies.
TONE
Use the TONE control to optimize the tonal balance of the amplifier output.
