TFE iQGSM R1 GSM module, up to 100 users

iQGSM R1 is a Czech GSM module that opens your gate when you ring it from your mobile. The module recognises a stored number and switches the relay. The call is not answered, so control is free of charge. This version has memory for 100 numbers and suits a block of flats, a smaller company or a holiday resort. Also available: the version for 10 and for 1000 users.

Wiring

1. With the power off, insert a SIM card with the PIN code disabled (the current module version uses a nano SIM).
2. Connect the antenna and 4 wires: two for power from the operator, two to the opening input. The wires may be at most 3 m long.
3. When the green LED is lit steadily, hold the button for 2 seconds (the blue LED lights up) and ring from the number you want to store.

Add further numbers by SMS commands with a password, up to 10 at a time. Change the factory password 1234 straight away; after installation we recommend locking the adding of numbers by button.

Control modes

• stored numbers only – the module ignores unknown numbers,
• SMS with password – no limit on the number of users,
• missed call from any number – low security.

The relay (max. 30 V / 1 A) switches for 1 second to 24 hours or permanently. The module has protection rating IP50. In a metal enclosure or with a weak signal, add an external GSM antenna.
