28 Installation and Programming Guide
Installing Antennas
Several antennas may be provided depending on the model purchased. These include:
• Multi-antennas for ITI 63-bit, ITI 80plus.
• 3G/4G antennas for WiFi/cellular module
• WiFi antennas for WiFi/cellular module
Wireless Sensor Antennas
If two antennas have been provided:
1. Install panel into metal enclosure.
2. Install antennas vertically for best performance.
3. Each antenna is keyed (shaped differently) and
labelled. Antennas are reasonably flexible but do not
apply excessive force. Match the antenna to the
shape molded on the plastic bracket and push to
insert.
4. The line printed on each antenna will disappear
when fully inserted.
5. Remove antennas before attempting to remove
panel.
6. Antennas can be tampered monitored be enabling
Advanced – General Options – Antenna Tamper.
4G Cellular and WiFi Router Module Antennas
If the optional 4G Cellular and WiFi Router Module
has been installed, a single set of antennas should be
connected to “MAIN” on the module. The antennas
should be installed vertically, and as high up as
possible.
The module includes MIMO wireless technology to
improve reception of 3G/4G and WiFi wireless
signals. This requires the installation of a second set
of antennas to “DIV” on the 4G/WiFi Router Module.
The second set of antennas will perform best when
separated from the MAIN antennas by at least 20cm.
