Intercom Interface
The U9120-W4 (EU) is designed to add wireless capability to the Digital Intercom System.
Mounting
Select a location on a flat surface that is out-of-the-way, and provides adequate room to attach
all cables. The U9104-W4
(EU)
is immersion-proof (IP67). However where possible the mounting
location should be chosen to minimize direct exposure to the elements.
Position the endpoint on the surface to be mounted and mark the (2) hole locations.
Drill the (2) holes with 3/16-inch drill
bit.
Mount the endpoint with #8 mounting screws and nuts/lock-washers (customer supplied).
Alternately, the U9104-W4 (EU) may be flush-mounted with the optional flush-mount kit
(M9110FM, 44004G-02) or the 44003G-01 gasket-mount kit.
Antenna
The U9120-W4 (EU) has an internal antenna. An external antenna may not be necessary but the
antenna connector is provided for either the included whip antenna or an optional remote
antenna kit (P/N: 40688G-93 for mag-mount, 40688G-96 for permanent install).
Choose an open, clear location for the remote antenna, away from other RF-emitting devices,
and route the coaxial cable away from any busy areas, preferably behind panels or in conduits.
This device has been designed to operate with the antennas listed below, and having a
maximum gain of 3 dB. Antennas not included in this list or having a gain greater than 3 dB are
strictly prohibited for use with this device. The required antenna impedance is 50 ohms.
