Paradox FD25M-M5U M-Series Wireless Water Leak Detector

The Paradox FD25M-M5U (FD25M) is an official wireless water leak detector engineered for the Paradox M Series security ecosystem. Designed to provide early warning of water leaks, floods, and pipe bursts, it helps prevent costly water damage in residential and commercial properties. Operating over encrypted GFSK 2-way wireless communication (868 MHz or 914 MHz), it detects water contact via its integrated stainless-steel sensing probes and immediately sends real-time alerts to Paradox control panels and the BlueEye mobile application.

Key System Features & Functionality

• Instant Water Leak Detection: Dual stainless-steel contacts at the base detect water presence as low as 0.5mm depth to trigger immediate alarms.

• Encrypted GFSK 2-Way RF: Operates over secure 2-way wireless frequencies with automatic frequency and encryption hopping for maximum signal reliability.

• Integrated Temperature Sensor: Monitors ambient room temperatures continuously to alert users of potential freezing pipe conditions.

• Long Battery Life: Powered by a long-lasting lithium coin/cylindrical cell designed to deliver up to 3–5 years of standby operation.

• Built-in Piezo Buzzer & LED Indicator: Local acoustic alarm and visual LED status give immediate feedback on water detection, low battery, and supervisory signals.

• Water-Resistant Sealed Casing: Compact IP-rated housing designed for placement directly on floors near washing machines, water heaters, basements, or under sinks.
