Testing
Once all configurations are complete perform a full commissioning test with the monitoring centre. This will
normally involve testing normal alarm transmissions over all communication paths from the alarm panel to the
monitoring centre, and verifying that these are successfully received.

Main menu
The IRIS Connect has a number of options under the main menu and
below we will go through each section explaining their functions and
uses.
GPRS/3G Network Scan
IRIS Connect Duo with GPRS/3G connection:
The GPRS/3G network scan function allows overall feedback of signal strength from all providers in the area. This
should be performed on installation as detailed in
Section 7 “Installing the IRIS Connect Dialler”
and also after
installation, for example during maintenance, as location signal stregnth can change e.g. new building in the area or
cosmetic changes in the current location (storage racking etc).
The scan must be carried out
without
the SIM card fitted.
The dialler listens for every base station in range, requests operator name and records the signal strength.
This will take a few minutes to complete.
For a reliable GPRS/3G connection it is recommended that for the chosen network (SIM card) used there should be
at least two base stations with signal strength (CSQ) of 10 or more for reliability.
If the signal strength is below or close to minimum then try to reposition the IRIS Connect or use an external high
gain antenna (if necessary), and rerun the network scan.
Once the required GPRS/3G signal strength has been obtained power down the dialler and insert the SIM card into
the SIM card holder, then insert the 4 x AA batteries if required and power the dialler back up.
