DESCRIPTION
Bogen Model TPU-15A is a unique fifteen-watt, wall-mounted
amplifier, specifically designed for telephone paging applications.
This compact unit incorporates state-of-the-art electronic technology,
including voice-activated muting of music when paging. The page
channel features automatic output leveling (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 per¬
sonnel 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 25 volts, 70 volts,
or 8 ohms for connection of various types of loudspeakers.
Model TPU-15A features screwdriver-adjustable controls for page,
music, and night ringer level, plus amplifier tone. Protective devices
include an LED overload indicator and a low-cut switch for use with
horn loudspeakers. The unit is professional in styling and is finished
in black with white lettering. It operates from a 120VAC, 60Hz source.
INSTALLATION
CAUTION
The fallowing installation instructions are far use hy
qualified service 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 nr shock hazard, da
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 shipping ma'terial, notify the carrier immediately and place
your claim.
POWER AND GROUNDING
The AC line cord has a three-prong plug which should be plugged
into a three-wire, grounded 120V, 60Hz outlet. It is important to
ground the unit. If a three-wire outlet is not available, use an adap¬
tor and connect the grounding pigtail to the screw securing the wall
plate. If the wall plate screw is not grounded, connect a wire from
the ground terminal of the amplifier to a suitable earth ground.
MOUNTING
Model TPU-15A is designed for surface wall mounting. When
mounting the unit, consider the proximity to heat sources and power
supply, adequate air flow for chassis heat dissipation, and access to
controls and terminal wiring, Where possible, secure to wall studs
or a suitable back brace. Use self-fastening or molly-type hardware
on plasterboard and other thin materials.
INPUT CONNECTIONS
PAGING
A balanced transformer-isolated input for a telephone line is pro¬
vided. One 600-ohm telephone line may be connected at the terminals
marked TIP and RING If tuo-conductor shielded wire is used, con¬
nect the shield to the GND terminal.
MUSIC
An unbalanced high-impedance auxiliary input is provided. Make
connections to terminals marked MUSIC and GND.
NIGHT RINGER
A ringing tone can be transmitted through the public address system
by connecting the NIGHT RINGER and GND terminals on the
TPU 15A amplifier through a pair of normally open dry contacts
(which are customer-supplied). A steady ringing tone will be heard
as long as the dry contacts are closed.
