Cellular Radio Installation Sheet
Product Summary
This module adds 3G or 4G/LTE cellular radio capability to the
ZeroWire to allow reporting of system events.
Note: UTC reserves the right to check if the UTC SIM card is
used in the correct modem. Improper use of the modem or SIM
card can result in the product to stop operating with the
UltraSync infrastructure.
Installing The Module
1. A mobile phone can provide general guidance on mobile
network coverage.
Look at the signal level on a mobile phone to verify there
are 4/5 to 5/5 bars of reception in the location where you
will install the ZeroWire.
If the signal strength is low, find another location which
has stronger signal levels.
Note that actual signal level can only be determined using
the ZeroWire connected to a specific network, which may
be different than your phone.
2. If a cellular radio module is pre-installed, skip to the Check
Signal Level section. If not, remove the cover on the right.
3. Locate the 10-pin lead inside the ZeroWire and connect
this to the radio module.
Check Signal Level
Select main menu - Option 4,
System Test.
Enter your Installer code.
Check Cellular Signal Level
Exit from the Advanced
system configuration menu.
•If the reported value is -88 to -51 then the signal level is
OK. In this case, please jump to the Completing
Installation section.
•If the reported value is -121 to -89 then installing an
external antenna is recommended. In this case, follow
steps below to install an external antenna to improve
the signal level.
Note: Remember that signal levels vary day to day and are not
absolute values.
Installing The Optional External Antenna
(ZW-ANT3M)
1. Disconnect the antenna cable from the radio module.
