Water Leak Detection Systems for Airports

water leak detection system in airport

Early detection of water leaks in private, municipal, or commercial airports is an essential part of maintaining employee and traveler safety. Preventing hazardous conditions caused by water leaks also reduces the risk that airport owners, lessees, and tenants are found liable for injury claims or damage. Modern airports are complex facilities facing a variety of predictable and unpredictable demands. Protection against undetected water leaks promotes smooth operations so important resources can remain focused on security, efficiency, and other priorities.

Water Alert leak detection equipment is easy to install and provides continuous monitoring 24/7. Water Alert leak sensors are convenient, durable, warrantied, and ideal for use in airports of all sizes.

Water Alert Models Recommended for Airports

Water Alert Model SS-4 has no audible alarm and ties into an existing alarm panel or BMS (building management system). Isolated dry relay contacts transfer and hold when activated, and self-reset. This model is available with three powering options and can also accept and monitor one or two lengths of water sensor cable.

Water Alert Leak Detection Cable can detect the presence of water from zero to ⅛” height and comes in standard lengths of 12, 24 & 36 feet. Our liquid leak detector cable is used for large areas or perimeter monitoring. Unlike coaxial or helical leak detection cables, the Water Alert sensor cable won’t absorb, track, or wick moisture.

Water Alert Vandal Resistant (VR) Series leak sensors are designed for use in restrooms and other areas that require frequent cleaning, with a “Wash-Down Mode” feature that prevents activation. Model VR-4 and VR-2100 have no audible alarm, tie into existing alarm panels or BMS, and provide isolated dry relay contacts that transfer and hold when activated (also self-reset).

Water Alert Ceiling Guard water leak sensors are installed easily above suspended ceiling tiles to detect small amounts of water from piping, roofing, and upper floors. Individual leak-sensing trays are interconnected to form zones of protection, alerting you to the presence of water before it leaks through or along the edge of tiles into the area below. Perfect for drop-in ceiling tiles in airport terminals lounges, restaurants, and employee break rooms.
