INSTALLING THE CA CABLES
8.
Slide a Bend-Relief Grommet over one end of the flat CA Cable, small end first.
9.
Attach a RJ-12 Modular Plug to the end of the flat CA Cable (see page 28 for
instructions if necessary).
ALWAYS make sure the printed side of the cable is facing the release-tab on the
RJ-12 Modular Plug (Figure 13). This ensures proper orientation of the plug on
each end of the cable.
10. Remove the screws holding the HM-10 together (Figure 11) and remove the
bottom plate of the HM-10.
11. Lift the modular jack slightly out of the HM-10 and insert the RJ-12 Modular Plug
into the jack in the HM-10 as shown in Figure 12.
If the CA Cable is going from the Headset Module to the Intercom, it MUST be
inserted into the Modular Jack on the same side of the HM-10 as the “Firecom“
label. If the CA Cable is part of a “daisy-chain“, you will need to remove the
plastic tab which covers the access hole to the second Modular Jack on the
HM-10. See “Daisy-Chaining“ the Headset Modules (page 8).
