MODULAR PLUG INSTALLATION
This section describes the installation of the RJ-12 Modular Plug onto the flat CA Cable.
1. Using the cutter blade on the crimping tool (labeled
A
in Figure 6), cut the flat CA Cable so the cut is clean and
90 degrees to the sides of the cable.
2. Fully insert one end of the CA Cable between the stripping blades (labeled
C
in Figure 6) until the end of the cable
hits the stop (labeled
B
in Figure 6).

3.
Squeeze the handles of the crimping tool together until the tool bottoms out.
4.
While holding the handles together, pull the cable out of the tool.
5.
The stripped insulation should expose approximately 3/16” of wire (Figure 7).
6. Push a RJ-12 Modular Plug into the plug holder on the crimping tool (labeled
D
in Figure 6) until the release tab on the plug locks
into position.
7. Holding the cable so that the printed side of the cable is toward the release-tab on the plug, push the cable into the plug as far as it
will go.
ALWAYS make sure the printed side of the cable is facing the release-tab on the RJ-12 Modular Plug (Figure 8). This
ensures proper orientation of the plug on each end of the cable.
8. Squeeze the tool handles
COMPLETELY
together. You may feel the crimper punching the
contacts through the insulation on the wires.
9. Let the handles spring open.
10. Push down on the release-tab on the RJ-12 Modular Plug (Figure 8) and remove the RJ-12
Modular Plug from the crimping tool.
11. Inspect the plug to ensure that the cable is held securely in place.

SYSTEM TEST
REMOTE HEAD TEST
1. Press the VOLUME up and down buttons on the Remote Head front panel. The Main Intercom LED’s should show the volume level
changes.
2. Press the SQUELCH up and down buttons on the Remote Head front panel. The Main Intercom LED’s should show the squelch level
changes.
3. Press the AUX 1 button on the Remote Head front panel to light the green and blue LED’s. The Main Intercom LED’s should show
the same LED changes for AUX 1. Repeat the operations test for AUX 2, 3, and CELL buttons.
4. Press the RADIO A button on the Remote Head front panel to light the yellow, green, blue, and red LED’s. The Main Intercom LED’s
should show the same LED changes for RADIO A. Repeat the operations test for RADIO B, C, and D.
ADVANCED TROUBLESHOOTING
REMOTE HEAD DOES NOT WORK
1. Make sure the CA cable plug is inserted completely into the Remote port of the Main Intercom.
2. Inspect the CA cable plug end to insure the plug is wired correctly (Figure 9)
3. Contact Firecom for a Return Materials Authorization (RMA) number to return the Remote Head for repair.
