Determine the Signal Strength and Select a Location
The IGSMV must be mounted indoors within the protected premises. When choosing a
suitable mounting location, understand that signal strength is very important for proper
operation. For most installations using the supplied antenna, mounting the unit as high as
practical, and avoiding large metal components provides adequate signal strength for proper
operation.
You will use the communications module to determine signal strength in order to find a
suitable mounting location.
Note: If the SIM is already activated, the RSSI signal strength indicators will indicate
signal strength.
If the SIM has not been activated, the firmware in the communications module enables it
to communicate with the cellular network towers (without the SIM being activated) so
that signal strength measurements can be determined. In this case, you can display the
signal strength by simultaneously pressing the MODE and TAMPER switches.
RF Exposure
Warning
– The antenna(s) used for this transmitter must be installed to provide a
separation distance of at least 20 cm from all persons and must not be collocated or
operating in conjunction with any other antenna or transmitter.
Note: The IGSMV must be installed in accordance with the National Fire Alarm Code,
ANSI/NFPA 72.
Unshielded, 22 AWG cable is recommended for IGSMV power/data wires.
1. Unpack the IGSMV and detach the case back by pushing up into the two tabs located at
the bottom of the IGSMV with the blade of a screwdriver while pulling the case back and
case front apart.
2. Temporarily connect the IGSMV to the AC transformer, supplied.
3. Choose the installation site with the best signal strength by observing the signal
strength (RSSI) bar graph (refer to Appendix A for information about signal strength and
status indications). Signal strength should be within 3-5 bars. The best signal strength
is usually found at the highest point in the building, near a window. Unplug the
transformer.
