HME B7000 Drive Thru Wireless Intercom
Quick Reference Installation Guide
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. The IB7000 power LED illuminates green when it is connected to a powered on base station. The max IB7000 cable length to guarantee operation at max volume should not exceed 500 ft (152 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.

INSTALLING THE WEATHER COVER
The IB7000 Weather Cover must be installed onto the IB7000 to protect the electrical connections from cooped the electrical connections from corrosion due to water/moisture ingress.
(Even when installed in a speaker post or menu board, these locations do not guarantee a sheltered envi-ronment for the IB7000.)
When installed, the top of the weather cover completely seals the IB7000 on top to prevent water or moisture ingress. The bottom has an opening to allow all the IB7000 cables to exit beneath the IB7000 once the cover is in place.
Note: The cover must be oriented and installed the correct way to be effective (see Fig. 4).
- Orient the weather cover correctly before installing (see the up arrow on the cover rear, Fig. 4 & 5).
- Attach the cover by first placing the top latch over the ridge and housing seam of the IB7000 (Fig. 6).
- Then, hinge the bottom part of the cover onto the bottom part of the IB7000. If there is resistance, the bottom latches are flexible and can be pried onto the IB7000 (Fig. 6).
- Verify all the IB7000 cables exit through the opening at the cover bottom before pressing in on the cover to close. The cover will snap securely into place (Fig. 7).
Note: To remove the cover, do so in reverse order to the above steps. First, use your fingers to pry the flexible latches on the cover bottom as you detach it from the IB7000 ridge and housing seam it is grip-ping. Hinge outward away from the IB7000 until the top freely detaches.
