RFUN Wireless Reed + Input — Australian Stock & 3-Year Warranty

The Bosch RFUN is a versatile RADION-series wireless reed switch with an external input. It works as a standard door/window contact via its built-in reed and 12.7mm gap, and its one dry-contact input also lets you make almost any wired device — a roller-door contact, PIR, or third-party detector — wireless. Powered by a long-life CR123A battery with screw terminals for easy wiring, it is the flexible “universal” transmitter for RADION systems, backed by a 3-year Australian warranty.
