Power supply

bTAG is prepared for two types of power supply: battery (via 2 CR2032 coin-cell lithium batteries included in the package) or via mains cable for connection to the electrical system. It is up to the installer to choose which of the two options to use according to the needs of the homeowner.

If powered by electricity, the reader automatically detects the tag when it is nearby.

The battery-powered version, on the other hand, is usually in power-saving mode and must be activated by pressing the appropriate button on the device before the credentials stored on the tag can be read.
