4. INSTALLATION
Disconnect power before making any electrical connections.
It is not advisable to power up the device if the antenna is not connected.
The GSM module should be installed indoors, in spaces with normal air humidity.
The module power supply should have a sufficient output current and be provided with
a battery. It is recommended that it be placed at a distance of 3 m or less from the module.
When the supply voltage drops below 9.8 V, restart of the module occurs.
The following installation procedure is recommended:
1. Connect the antenna to the on-board connector. If thick masonry walls, metal partitions
etc. at the module installation place reduce the range of radio signal, use an antenna
which can be installed at a location some distance from the module, where the correct
level of GSM signal can be obtained. Do not install the antenna in parallel to the low-
voltage electrical installation wires, because this may cause interference.
2. Connect the control panel, telephone or another device equipped with telephone dialer to
the R-1 and T-1 terminals.
3. Connect the power cables to the +12V and GND terminals.
4. Turn on power supply of the module.
5. Using the suitable function, enter the PIN code of SIM card (if required by the SIM card).
6. Turn off power supply of the module.
7. Insert the SIM card into the socket (see: Fig. 4).
8. Turn on power supply of the module. Logging the telephone into the GSM network may
take a few minutes.
If the SIM card PIN code is not programmed within 10 minutes of power-up, the
telephone line voltage will be turned off.
After the third attempt to use the wrong PIN code, the SIM card will be blocked. To
unblock the SIM card, insert it into a mobile phone and enter the PUK code or use the
function [16].
