Sectron GSM Key SMART 3T GSM module, up to 1,000 users

Sectron GSM KEY SMART 3T opens the gate when you ring it from your mobile phone. The module compares your number with its list and switches the output. The call is not answered, so operation is free of charge. The T version is intended for mounting at the operator. It suits apartment buildings, businesses, hotels and car parks.

Functions

• Two outputs – OUT1 and OUT2 control two devices.
• Two inputs – IN1 and IN2 for limit switches or other sensors, so you know the gate status.
• Management – SECTRON GSM KEY app, SMS or the SMART 3 Admin program via USB. GSMKEY.cloud remote management is a paid service.

Commissioning

1. Activate the SIM card in a mobile phone with an outgoing call, disable the PIN and voicemail, delete contacts and SMS messages.
2. Insert the card into the module, screw on the antenna and connect output OUT1 to the START terminals of the operator.
3. Connect the power supply last; the blue LED starts flashing within a minute.
4. Send the SMS “ADD MASTER +421xxxxxxxxx” with your number. Until then, the module opens for anyone who knows its number.

Install the module indoors or in a waterproof box. For fewer users, GSM KEY LITE 3+ is sufficient; with a weak signal, an external antenna helps.
