GSM-4M GSM modem to MD...

GSM-M4 modems enable remote monitoring of the status of a gas detection system with MD type control modules manufactured by GAZEX.

The kit consists of a GSM 900/1800 type GSM-X modem with a built-in control and power cable, an external GSM antenna with a flexible connection cable, and a USB connection cable for PC.

After connecting the GSM-M4 to the MD type control unit terminal, each change in the status of the module’s relay outputs causes a text message (SMS) to be sent to the mobile phone number(s) selected by the user.
