12V DC Wired Water Detectors Water Leak Alarm Module Leakage Flood Sensor with 10A NC NO Relay Output Control, Turns Off Flood Source (White)

Introduction: This wired water detection alarm module is an efficient, low-voltage device designed to activate both audible and visual alarms, as well as initiate relay switching when water presence is detected. All components are mounted on a PCB with terminal blocks, protected within a durable plastic casing suitable for surface installation. The system accommodates the supplied sensor or compatible alternatives, allowing for adaptable usage. Comprehensive supplier documentation provides detailed specifications and application examples, while suitability should be evaluated based on specific safety and operational requirements. Typical Control Functions and Capabilities: Equipped with SPDT relay contacts, the module facilitates seamless integration with external systems or enables direct device control during alarm conditions. Multiple modules may be interconnected to support centralized monitoring and customized control strategies, enhancing utility for DIY applications and specialized installations. Application Notes: This product was implemented in a dedicated low-voltage, five-zone residential leak detection and water damage mitigation solution. Relay contacts were configured for unified output, enabling any detection event to automatically actuate motorized valves incorporated into the water supply infrastructure. Centralization of audible alarms was achieved by disabling onboard signaling, and manual reset capability was introduced to supersede the default auto-reset function. Sensor mounting approaches were tailored to each monitored zone, utilizing alternative probes where appropriate. Standard two-wire low-voltage cabling proved effective throughout the property, with probe sensitivity adjustments made as required. All system components operated on 12VDC and were housed within a wall-mounted PVC enclosure featuring a transparent cover. Provision was made for external wiring via jacks supporting valve connections and a plug-in 120VAC/12VDC adapter supplying power to the entire assembly. Additional Comments and Recommendations: Ensuring proper wiring practices, adherence to applicable electrical codes, and restricting relay terminal connections to low-current loads are critical to maintaining operational safety. It is important to note that the safe load capacity for relay contacts may be significantly lower than the maximum specified rating, depending on the particular application and installation conditions. While operation at low voltage and low current is likely to enhance component longevity, frequent activation cycles or extended immersion of the sensor probes may adversely affect the overall lifespan of the system. To ensure reliable performance, it is advisable to conduct routine system testing and maintain an inventory of spare parts for timely maintenance and repairs as necessary.

I used as water detection device for the overflow drain pan on my Air Conditioner. This will detect even a small amount of water and I have it wired to turn the AC off if water is detected. It has a much quicker response than the standard mechanical float system.

We bought this because we have a water cooler that occasionally leaks if the pump gets stuck on. The water cooler sits on a mat in the barn and we have the sensor sitting down on the mat. If the pump stays on and leaks, the sensor reads it and the relay kicks on and turns off the system. I have a 12 volt power supply separate from the cooler to power this up. Pretty slick switch for $20.

I would give it 5 stars, but some of the components are a bit flimsy. The button to turn off the buzzer feels like it will break if you dont treat it very carefully, and the wire insertion point terminals can be a finicky.

Works like it should.

Buen producto, trae un buzzer integrada al momento de activarse

First one the black smoke got out when first connected

I do a lot of remote monitoring of water treatment sites (pump stations, RO facilities)... and leaks are an important thing to monitor. This unit will provide an audible alert when a leak is detected... it also has a relay with NO and NC dry contacts that I can easily connect to my gateways for remote monitoring and alerting. I like that I can adjust sensitivity if I need to. Easy to test it with the type of water that you are working with. 12 VDC power requirement is compatible with my gateway... I like that too. Reasonable cost as well.
