The Paradox FD25M is a compact wireless water detector designed to help identify unwanted water presence before it becomes a major issue. Using integrated detection probes, the FD25M can detect water contact and trigger an audible alert, helping provide early warning of leaks, flooding, or water damage risks.
Designed for seamless integration with compatible Paradox M-Series alarm systems, the FD25M uses secure GFSK two-way wireless communication with frequency and encryption hopping. It also includes temperature sensing, long-life battery operation, and support for water supply valve control when used with compatible equipment.
The FD25M is ideal for residential and commercial installations where early leak detection is important, including bathrooms, laundries, kitchens, hot water systems, under-sink cupboards, basements, server rooms, storage areas, and other water-sensitive environments.
