Installation
There are two ways to test the signal strength in advance:
1. Via temporary installation of the GSM module in the alarm system
For this method, please observe the steps described for the use of the module in this
user guide. Before doing this, ensure that the SIM card that is used has been registered.
Make sure that the SIM card is not blocked with a PIN.
2. By using a mobile phone
For this method, ensure that the SIM used for the test is from the same provider, or
temporarily use the SIM card that will ultimately be used in the GSM module in the
mobile phone. Hold the phone in the exact place in which you want to install the GSM
antenna and check the signal strength.
If you have found a position with good signal strength (at least 2 bars on
the phone), ensure that the centre of the antenna is located within 2 cm of
this point, because the GSM wavelength is very short and even small
Note
discrepancies may lead to a significant deterioration of the signal. This
could significantly effect operation, in particular when the level is generally
poor, and may prevent the registration of the module in the GSM network.
Use of the GSM module
If the alarm panel is already in operation, put the panel into installation
mode. This ensures that opening the housing will now not trigger a
sabotage alarm.
