(^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.

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.

( 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.

3) Paging speaker line connections;

a. Heaviest possible gauge of wires should be run from PG-3

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

b. When paging speakers are installed in multiple (Up to four

8 ohm paging speakers are installable), run 2 separate wires from PG-3’s |2i2[ and |COM| terminals to each 8 ohm paging speaker.

C ADAPTOR REQUIREMENT^

PG-3 can add the feature of paging to relatively small area, where one 8 ohm paging speaker is installed. The following

requirements MUST be met for paging adaptor and power supply.
