Technical specifications for the Metak Water Leak Detector describe a standalone analog safety tool utilizing a continuity-based sensing circuit. When water bridges the two metallic contact points on the base of the ultrasonically welded plastic chassis, a high-decibel circuit is closed. The integrated piezo siren is rated for a 100dB output, powered by a 9V battery architecture that provides a higher voltage rail than standard AAA or button cell configurations.
Material analysis indicates the chassis is non-serviceable, designed to provide water resistance for the internal electronics during leak events. Performance metrics confirm the device functions without a central hub or firmware, prioritizing immediate local acoustic notification. Standardized testing shows the 100dB signal remains audible through closed cabinetry and floorboards.
Operational maintenance requirements include:
- Probe Cleaning: Annual removal of oxidation layers from contact points to maintain sensitivity.
- Manual Testing: 6-month cycles to verify acoustic integrity in the absence of digital status reporting.
- Standalone Operation: Zero capability for smartphone integration or smart home logic.
For users seeking to upgrade from passive sirens to a localized digital mesh, the Aqara Zigbee sensors offer a low-profile alternative with high-speed data reporting. Aqara 3 Pack Water Leak Sensors for Smart Homes
This unit is a fundamental component of the water leak detectors classification for localized alerting.
