Fire-Lite FC-XRM70 Installation

The optional FC-XRM70 Transformer Module can be used
to convert the 25 V
RMS
Transformer connector J1 plugs into amplifier connector P1.
CAUTION! Make certain to observe all of the following conditions:
1. Remove all power (AC and DC) before making any connections.
2. Install the FC-XRM70 option module ONLY on Voice Evacuation Control Panels with the following printed
circuit cards installed (refer to the VECP Installation Manual for additional information):
FC-AAM25X Audio Amplifier Module (FCAAM25-PCB stamped on the circuit board) with
• Main circuit board identified by software version FC25502.0 or higher (refer to Fig. 1) or
• Main circuit board identified by software version FCDA25501.0 or higher (refer to Fig. 2)
ACC-AAM25 Audio Amplifier Module (ACCAAM25-PCA stamped on the circuit board) with
• Main circuit board idnetified by software version ACC25501.0 or higher (refer to Fig. 3)

FC-XRM70 Transformer Module Installation

1. Remove three mounting screws from the top left, top right and bottom right corners of the Audio Amplifier Module(s). Refer
to appropriate illustration.
2. Carefully unplug the Audio Amplifier Module(s) from the main circuit board connector. If two Audio Amplifier Modules are
installed, note where each is positioned on the main circuit board. (Switch S1 on each amplifier may be set differently).
Refer to appropriate illustration.
3. Install the three standoffs supplied with the FC-XRM70 Module by inserting the threaded male end of each standoff into the
three holes on the component side of the Audio Amplifier Module(s). Secure each standoff in place with a supplied nut.
Refer to the illustration on following page for the location of the mounting holes.
4. Reinstall the Audio Amplifier Module(s) by carefully aligning the Amplifier's J1 connector with the P4 or P3 (depending on
where it was removed from in step 2) connector on the main circuit board. Press the Audio Amplifier Module securely into
place, making certain not to bend or break any connector pins.
5. Secure the Audio Amplifier Module(s) with the screws removed in step 1.
6. Remove two factory installed jumpers from connector P1 of Audio Amplifier Module(s). Refer to illustration on page 4.
7. 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 any pins.
8. Secure the FC-XRM70 Transformer Module(s) to the Audio Amplifier Module(s) with the supplied screws.
