2. Mounting the Optional Gooseneck Microphone or Headset
Plug the Gooseneck Microphone into the mini RJ11 plug labeled "GOOSENECK MIC"
on the back of the Master. Mount the Gooseneck Microphone so that the Interviewer
will be able to speak comfortably. (You may wish to mount the microphone
temporarily in order to try different locations before mounting permanently.)
For the wireless headset, attach via the mini RJ11 to the plug labeled "HEADSET" and
the plug labeled "TEL." on the handset base.
3. Connecting IW-HFM-4 Master to the Junction Box
The cable from the junction box connects to the RJ45 female connector on the back of the
Master. To avoid damage to the RJ45 male connector, cover this connector before
pulling through conduit or equivalent.
4. Connecting Sub-Station to Junction Box
The three-pair shielded cable from the Sub-Station should be connected to the white
“euro” type terminal block inside of the Junction Box. Connect all wires as shown in
the diagram below. Note that ALL 3 shields should be connected to the terminal
marked shield in the diagram below.
Figure 2. Master/Sub Terminal Block
IMPORTANT NOTE: Be sure to connect the white and black/white wires to the same
terminals as pictured above. Failure to do so may cause the power supply to overheat
and burn out.
5. Connecting the Paging Cable from the First Junction Box
The bus cable, which connects all Masters to the paging system, consists of a cable that
runs from one Junction Box to the next until they are all connected. At the end of the
Paging Bus, the Interface Boxes are all connected.
In the Junction Box for the first Master, connect all wires to similar terminals on the
Junction Box for the next Master as shown in Figure 3 below.
Note: Connect both shields to the terminal marked “SHLD”.
