Multi-function bidirectional magnetic contact ideal for wireless door/window protection in residential and small business applications. It is a cost-effective transmitter that combines a magnetic contact for Doors/Windows with two additional and separate channels for as many separate inputs (one universal and the other universal or for blind detectors). By having two separate channels, the RWC73F can be used in two different types of applications: For the protection of doors and windows when 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 security applications. The RWX73F has two reed switches for protection against the opening of doors and windows and against any attempt to sabotage the detector by approaching powerful magnets. It is compatible with any RISCO Group two-way wireless system.
