Working principle:

The GSM 58 is installed in the elevator cabin and connected to the audio module (if there is no one available in the elevator, see the GSM58K kit). A SIM card from a mobile operator is inserted into the communicator. According to the method described in detail in the manual, up to 8 numbers are registered for the GSM communicator to call when the emergency button is pressed in the elevator cabin. If the first phone in the order of ringing does not pick up, the communicator rings the next one, and so on. For the communicator to ring, the button must be held down for 2 seconds. but this time can be changed using the setting described in the manual.

How is it set up?

The communicator is set up by command SMS sent from the master number (the phone number of the owner). Through these SMS, monitoring zones, other user phone numbers and all other settings of which the communicator is capable are set. The in-product manual describes these commands in detail.
We have also developed a free phone application that makes it easy, convenient and understandable for everyone to program, control and receive information about your communicator. Communication between the application and the GSM communicator is carried out by calling and/or SMS.
