Product Q&A

Q:How does the GSM-KEY system work?

It uses Caller ID to recognize authorized numbers. When a call comes in, it checks the number against its memory list, rejects the call to avoid charges, and opens the gate.

Q:What is the maximum number of authorized users?

The system can store up to 200 full phone numbers and 40 special numbers that allow entrance based on specific days and times of the week.

Q:Does it cost money to open the gate?

No. The system does not answer the call, so standard operators do not charge for the call. You only need an active SIM card which may have a monthly fee.

Q:How do I add or remove authorized phone numbers?

You can send an SMS starting with a password to the GSM-KEY number, indicating the phone number to enable and its position. Only the person with the password can modify the list.

Q:Is it difficult to install the device?

Installation is simple. You connect two wires from the box in parallel with the gate's push button, connect to AC power (230V 20VA), insert a SIM card, and program numbers.
