HME NEXEO HDX IB7000 Quick Reference Installation Manual

The IB7000 is an interface box used to connect the loop,
microphone, and speaker to a NEXEO Base Station.

TOOLS/EQUIPMENT REQUIRED

• Screwdriver/Wrench for opening speaker post.
• Wire Strippers, cutters, and other standard tools used
for terminating cables/wires.
• Audio Cable (not included)

INSTALLATION AND SETUP

Fig. 3 shows how the IB7000 is typically connected.
Adhesive strips on the housing allow the IB7000 to be
affixed to a clean, dry surface inside the speaker post.
Note: The IB7000 must be mounted vertically, inside
the speaker post, close to the speaker/microphone.
This will help minimize audio hum and noise (thus, do
not mount the IB7000 too far away). The IB7000 power
LED illuminates green when it is connected to a powered
on base station. The IB7000 cable to the base station
should not exceed 1000 ft (304 m).
• The two-pin Loop connector connects to the ground
loop detector.
• The three-pin PLC/BASE connector connects to J4500
on the base station. This connection requires the
shield/drain to be grounded; see Table 1.
• The seven-pin DM5 MIC | SPKR connector connects
to the Microphone and Speaker; see Table 2.
• The five-pin RELAY | BCKP SPKR connector (optional)
connects to an intercom system like the IC300 if a
backup is needed in the event of a system failure.
