6.During changing or installing the battery, pay attention to the “+”,“-” poles of the battery and install it

correctly, or will damage the control panel or battery, even worse will put lives at risk.

Note

：

The gateway will be used with wired controller together

（

The LONWORKS gateway can be use

independently without wired controller
