Installation

8. Connect field wiring to newly installed amplifier.  Refer to Figure 3.12 on page 52 for 

illustration of speaker connections if amplifier is being used to expand system power to 50 
watts (i.e. providing dual 25 watt speaker circuits).  Figure 5.2 on page 82 for illustration of 
connections if amplifier is being used as a backup.

 speakers already exist or are to be installed.  Speaker wiring continues to be 

supervised during standby, alarm and while background music is playing when transformer is 
installed. Transformer connector J1 connects to amplifier connector P1.

1. Carefully remove the ACC-AAM25 Audio Amplifier Module(s) from the main circuit board.  

Figure 3.17 on page 58 for installation procedures and reverse the steps.

2. Install the three standoffs supplied with the FC-XRM70 Module by inserting each supplied 

screw into the three holes on the solder side of the ACC-AAM25 Audio Amplifier Module(s).  
Secure each standoff in place with the screws. Refer to Figure 3.18 for the location of the 
mounting holes.

3. Reinstall the Audio Amplifier Module(s) following the procedure accompanying Figure 3.17.
4. Remove the two factory installed jumpers from connector P1 of the Audio Amplifier 

Module(s).  Refer to the illustration in Figure 3.18.

5. Carefully align the J1 connector on the FC-XRM70 Transformer Module(s) with the P1 

connector on the Audio Amplifier Module and press securely into place.  Make certain the pins 
are properly aligned to prevent bending or breaking of pins.
