After this the unit goes back to sleeping modus. Batteries can be changed without unscrewing the device from the door or frame. The unit will give a visual warning on the device and sends a warning to the Z-Wave controller, when batteries need to be replaced. The units send information to a controller or any other associated Z-Wave device. Up to 5 devices can be controlled from this device.The device needs to be included into a Z-Wave network by a remote control or any other Z-Wave controller. For configuration of certain behaviour a static controller such as a PC with home automation software or a gateway is required.
