13. If the unit has a handset, pick up the front panel, and position it so the remaining handset wires can
be hooked up to the PCBA. For ease of installation, the handset wires are color coded as follows:
White See note below.
Black E2
Green E3
Red E4
Yellow E5
Blue E6
N OTE : For the Model 69701-006 PCBA, connect the white wire to E18.
For the Model 69701-009 and 69701-014 PCBA, connect the white wire to E41.
For all others, connect the white wire to E1.
18. If the unit is a Model 701-204, 701-205, or 701-304, reconnect the two 6-pin Molex connectors from
the front panel to the PCBA at J102 of the amplifier and to J103 of the Model 69072-001 PCBA.
19. Reinstall the transformer on the chassis using the two screws removed previously. The blue and
brown wires on the transformer should be facing up, or the chassis will not close.
20. Reconnect the 6-pin Molex connector to the PCBA.
21. Dress the VLC wires, and secure them with the tie wrap included in this kit.
N OTE : Ensure that the coil cord and the purple wire (if applicable) or hookswitch wires are routed
away from T1, which is located in the upper left corner of the PCBA.
22. Mount the front panel to the chassis, and tighten the four screws.
23. Plug the amplifier into the enclosure, and tighten the four screws.
N OTES :
1. Speaker adjustment for normal operation remains under the nameplate on the front panel and does
not change with the addition of the VLC. The speaker adjustment for the VLC is factory set and can
be varied by adjusting the level potentiometer on the VLC assembly.
2. When an alarm is broadcast and is accompanied by a VLC (50 kHz) signal on the page line, it
triggers the volume on the Page/Party
®
VLC amplifier to increase. GAI-Tronics Model 800 and 1200
Series cone speaker assemblies are normally used for indoor applications with low ambient noise,
such as offices, corridors, and control rooms. These speakers have a manual, wall-mounted remote
volume level control.
When these speakers are powered by a Page/Party ® VLC amplifier, and the volume level is manually
turned down using the wall-mounted remote volume level control, the signal that increases the
volume on the VLC amplifier will not bypass the manual setting. These speakers remain “turned
down,” regardless of the output signal of the amplifier, and the alarm broadcast level does NOT
increase on the cone speaker assemblies.
The Model 800 and 1200 Series speakers can be used in emergency notification systems; however,
we suggest that the customer NOT install the wall-mounted remote volume level control for this type
of application.
3. DO NOT READJUST the frequency potentiometer on the VLC assembly.
