ABOUT BRAND

Proactive Flooding Defense, Dual-Configuration Sensing

Product Description

The MWLT-2519 RF433 Water Leakage Sensor is designed to detect water leaks at the earliest possible stage, helping to protect buildings, equipment and valuable property from water damage. When water bridges the sensing contacts, the sensor immediately activates its integrated audible buzzer and LED indicator while simultaneously transmitting an RF433 wireless alarm signal to compatible ARC receivers.

Designed for flexible installation, the sensor can be placed directly on the floor or connected to the supplied 1.5-metre extension probe, allowing monitoring in difficult-to-access locations such as under appliances, inside cabinets or around water tanks. The optional wall-mount bracket provides additional installation flexibility while keeping the sensor securely positioned.

Compatible with ARC L-Series, M-Series and Matter + RF433 receivers, the MWLT-2519 can trigger lighting, continuous flashing alerts or door chime notifications depending on the connected smart home system. Its compact battery-powered design makes installation quick and convenient without requiring additional wiring, making it an ideal solution for homes, hotels, offices and commercial buildings.
