Introduction
The Bogen Model TPU
1
5A is a
1
5-watt wall-mounted amplifier, specifically designed
for telephone paging applications. This compact unit includes voice-activated muting
of music when paging. The page channel features Automatic Level Control (ALC) as
channel input varies, which is particularly advantageous where persons of varying
voice levels and paging techniques have access to the system. A night ringer (tone
generator) is provided; a steady ringing tone, indicating incoming calls, can be
transmitted through the public address system during other than regular business
hours. This alerts security personnel to answer the call.
Input terminals are furnished for a 600-ohm balanced telephone line, a background
music source, and normally-open dry contacts for the night ringer. Output terminals
offer a choice of 25V, 70V, and 8 ohms for connection of various types of
loudspeakers.

indicator and a low-cut switch for use with horn loudspeakers.
Installation
CAUTION:
The following installation instructions are for use by qualified personnel
only. To avoid an electric shock hazard, do not perform any functions requiring the
removal of the cover of the amplifier unless you are qualified to do so. To prevent fire or
shock hazard, do not expose this unit to rain or excessive moisture.
Unpacking
Your unit was carefully checked before leaving the factory; inspect the shipping
container and unit closely for improper handling. If the unit has been damaged, make
an immediate claim to the distributor from whom it was purchased. If the unit was
shipped directly to you, save all the shipping material and notify the carrier
immediately and place your claim.
The AC line cord has a three-prong plug which should be plugged into a three-wire,
grounded
1
20V ~, 60 Hz outlet. It is important to ground the unit.
Mounting
Model TPU
1
5A is designed for surface wall-mounting. When mounting the unit
consider the proximity to heat sources and allow adequate air flow for chassis heat
dissipation, and allow for access to controls and terminal wiring. Where possible,
secure to wall studs or on a suitable back brace. Use self-fastening or molly-type
hardware on plasterboard and other thin materials.
