- The sensor can work directly with selected EXTA LIFE receivers or indirectly via the logic function module in the EFC-01 controller.
- When the sensor works directly with the receiver, 10 different operating modes are available. Open/close detection is carried out by the built-in magnetic hall sensor.
- The device can be powered by batteries or an external power source. The sensor can be configured with an external power supply. Mounting with double sided tape or twisting.

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
