The Zircon Leak Alert + LED! comes in a translucent body cover and is made up of bright red LEDs flashing a SOS and a loud (90Db) alarm that will sound with any direct water contact. Protect your property from water damage by placing your Leak Alert + LED! any place that has potential for flooding or leaks such as near water heaters, sinks, dishwashers, sump pumps, and more. The Leak Alert + LED! is a water leak sensor and water alarm that requires an easily installed 9V battery. Each water detector alarm is battery operated, wireless and fully automatic so no wiring or hub is required. Just like your smoke detectors, remember to check, and replace your Leak Alert + LED! batteries every year. Should flooding occur, the water leak detector will float and continue to send out both visual flashing alerts as well as an auditory alarm so it can be both seen and heard from a distance. The Leak Alert + LED! has a low battery warning for optimum performance. The Leak Alert + LED! is the perfect water detector for HOA, multi-unit, and multi-story property managements. It is also the best water detector to protect your apartment, home, or office. Battery not included.
