By having two separate channels, the RWX73F can be used in two different types of applications: For the protection of doors and windows when it is connected to a single channel and for the protection of blinds since it can manage detectors with pulsed output. Each channel can be connected to magnetic contacts or other wired sensors, which can be used for various control and safety applications. CR123 3V lithium battery included.
