Installation of Option Modules
3.8.1 Audio Amplifier Module (FC-AAM25)
The optional audio amplifier module is identical to the module provided with the factory standard panel configura-
tion. It can be used to provide a second 25 watt speaker circuit, increasing the total VECP power to 50 watts, or it can
be used as a backup amplifier. LEDs on the amplifier module are for Amp Supervision (green - indicates amp func-
tional) and Circuit Trouble (yellow - indicates wiring fault or amplifier fail). Connector J1 of the audio amplifier
module plugs into connector P3 located at the bottom center of the main circuit board.
!
Caution: Before installing any modules, make certain all power (AC and DC) has been removed.
For ease of access, all wiring should be connected to the terminals on the main circuit board terminal blocks
1.
TB2, TB4, TB5 and TB6 prior to installing the secondary Audio Amplifier Module.
Remove mounting screw shown, from the main circuit board, and save (refer to illustration below).
2.
Install one supplied metal standoff in location from which mounting screw was removed in Step 2.
3.
Install the Audio Amplifier Module by carefully aligning the amplifier's J1 connector with the P3 connector

on the main circuit board. Press the Module securely into place making certain not to bend or break any con-
nector pins.
Secure the Audio Amplifier Module with the supplied screws plus the screw removed in Step 2. It is impor-

tant to secure the module with the metal screws in order to help protect against electrical transients.
Configure the Audio Amplifier for primary or backup amplifier operation by setting switch S1 on the

connections if amplifier is being used to expand system power to 50 watts (i.e. providing dual 25 watt speaker
circuits). Refer to Figure 5-2 on page 39 for illustration of connections if amplifier is being used as a backup.

1) Position switch S1 in the DOWN position for primary operation which adds the new amplifier's 25
watts to total system power (50 watts total).
2) Position switch S1 in the UP 'Backup On' position to configure the amplifier as a backup in the
event the primary amplifier fails.
