INSTALLATION
Do not attempt to install your PG-A amplifier until you have read and thoroughly understood the installation
procedure. Aiphone's warranty for the amplifier and the system is void if amplifier is installed in a manner other than
described in this manual.
ADAPTOR REQUIREMENTS
The following AIPHONE intercoms have paging capability and may be connected to PG-A amplifier in conjunction
with a paging adaptor. The type of adaptor must be decided according to the type of intercom system you install and the
paging mode you wish to have. Each paging block requires one PG-A amplifier and appropriate number of speakers.

Begin your installation by connecting the paging adaptor to your intercom system (and background music source
if required) by referring to the instruction sheet of the paging adaptor packed with each unit. Requirements stated on
the instruction sheet of the paging adaptor MUST BE MET.
After completing installation of both intercom system and the paging adaptor, then you may proceed to installation
of PG-A amplifier. Unplug both power supply for intercom system and amplifier while making wiring connections.
AMPLIFIER INPUT CONNECTIONS
The greater the distance between the paging adaptor and the amplifier will increase the possibility of picking up
R.F. signals or electrical noise.
The paging adaptor and amplifier should be located as close as possible to each other and shielded cable should
always be used to connect them.

SPEAKER REQUIREMENTS
CAP
2-CONDUCTORS (SPEAKER LINE)
1 It is imperative that the total power consumed for speakers MUST NOT EXCEED the output power of amplifier
ie. maximum 10 watts for PG-10A, 30 watts for PG-30A and 60 watts for PG-60A. Greater output than 60 watts
may be obtained by multiple installation of amplifiers. Refer to drawing below.
2 It is NOT REQUIRED to have a dummy load when the power consumed for speakers is less than the output power
of amplifier.
3 A low impedance speaker such as 8 ohm horn must be installed using a matching transformer.
4
The total impedance of all speakers, matching transformers, and length of speakers run must be equal or more
than the output impedance of the amplifier. Refer to chart below. After computing the resistance of your
speaker, transformers, and speaker line, add a resistor in series to speaker line to increase impedance to match chart.

WALL MOUNTING INSTALLATION
Your PG-A amplifier is designed either for shelf or wall mounting. -
Please avoid placing the amplifier on dusty or humid floor. FE
1) Each amplifier is shipped complete with screws and bracket for
wall mounting.
2) Attach the bracket to the bottom of amplifier.
3) Mount the amplifier upon the screws protruding from the wall.
4) Fix the attached bracket to the wall with the supplied screw.

FIELD SERVICING
BREAKER
Your PG-A amplifier is equipped with a circuit breaker to protect the internal circuit from overloads or
shorts in speaker line.
If you do not have any output to the speakers, make the following checks:
1. Check A.C. outlet — Unplug amplifier from A.C.
2. Check speaker line for either overloads, shorts, or opens — and repair.
3. Plug PG-A amplifier into A.C. outlet and press circuit breaker button.
FUSE REPLACEMENT
A slow blow fuse (1A for 10, 2A for 30, 3A for 60) is located on the rear of each amplifier. A blown
fuse is generally caused by internal circuitry. Turn amplifier off and replace fuse. If the replacement fuse also goes out,
refer amplifier to qualified personnel. |
