(^FEATURES )
Allows paging announcement to relatively small room or area (where only one paging speaker is installed) in conjunction
with Aiphone paging adaptors in TB-F, TB-H & KAH systems.
Allows paging announcement to relatively small room or area (where only one paging speaker is installed) amplifying the
output of LAF, HM-7 and LAH-20 (in conjunction with LAN-1).
Talkback paging is not available in LAF, HM-7 or LAH-20 systems.
C
INSTALLATION )
Do not attempt to install PG-3 until you have read and thoroughly understood the installation procedure. Aiphone’s
warranty is void if it is installed in a manner other than described in this manual.
1)
( WIRIN^
1) Amplifier input connections;
The paging adaptor and PG-3 (INPUT 1 | A | , El
terminals) should be located as close as possible to each
other. SHIELDED CABLE SHOULD BE ALWAYS USED
TO CONNECT THEM IN ORDER TO REDUCE THE
POSSIBILITY OF PICKING UP R.F. SIGNALS OR
ELECTRICAL NOISE.
2) Power supply connections;
a. PS-12 A (or PS-12C) power supply and PG-3 should be
located as close as possible to each other and 0.8 mm dia.
wires (20 AWG) or thicker should be used in order to
avoid drop of PG-3 output power.
b. LAF, HM-7, TB-F, TB-H & TS-K systems (TB-H: up to
12 phones);
One PS-12A (or PS-12C) power supply may be COMMON
LY used for both intercom system and PG-3.
c. KAH, LAH-20 & TB-H systems (TB-H: more than 12
phones);
One PS-12A (or PS-12C) power supply is required for the
intercom system and a second power supply is required
for the PG-3.
NOTE: When two or more PG-3 are installed in a system, one
PS-12A (or PS-12C) power supply MUST be used for
each PG-3.

to paging speaker.
Refer to the chart below and select the proper wire gauge
to meet your requirements.

AJUSTING CONTROLS
[ 1 j When using PG-3 in conjunction with paging adaptor in systems; TB-F, TB-H, KAH & TS-K;
1. After wiring, set paging adaptor TREBLE, BASS & VOLUME controls (and, of background music source, if in
stalled) and PG-3 VOLUME control at MIDPOINT.
2. Turn on the power supply and background music source (and power supply for PG-3, if installed separately) and
proceed with adjustments in the following manner;
Test operations for paging and talkback paging, as described in the manual.
(1)
During paging, adjust paging adaptor TREBLE, BASS & VOLUME controls to desired level.
(2)
In case paging volume level is too low after paging adaptor VOLUME control is set at maximum level, adjust
PG-3 VOLUME control to achieve the most desired level.
If background music is included, adjust paging adaptor MUSIC TREBLE, BASS & VOLUME controls (or in
(3)
background music source, if included) while listening to the background music.
(4) Adjust PRE-TONE VOLUME control on paging adaptor (PB-1 only).
I 2 I
When using PG-3 in system: LAP, HM-7 & LAH;
1. After wiring, turn on the power supply (and power supply for PG-3, if installed). Set PG-3 VOLUME control at
MIDPOINT.
(1) Test operations for calling and communication, as described in the manual.
(2) Adjust master station VOLUME controls for calling and communication (LAW-1 VOLUME controls in LAH-20
system) to desired level.
(3) On master station, select the number button assigned for paging (to which PG-3 terminal is connected) and
