Mount the control panel on a wall
Screw the wall mount onto the wall where you wish to install
your control panel. Fix the control panel on the wall mount.
A piece of advice
Make sure the control panel is firmly fixed on the wall mount.
Because of the tamper switch, the alarm rings out if the control
panel is separated from the wall mount.
Before mounting the control panel, make sure the GSM signal is
sufficient: make a phone call to your control panel's SIM card. Once
you are through, press 1234# and then 1 on your phone. If this
operation arms your system, the GSM signal is sufficient. If nothing
happens or if you go to voice mail, the GSM reception is not sufficient.
