The Sensaphone zone water detection sensor detects the widespread presence of water in areas such as floors or drop ceilings. Users receive an alert when the sensor comes into contact with water. The sensor includes 10’ of water rope to cover a large area. Operators can connect up to 10 water ropes to a single sensor for up to 100’ of coverage. The sensor operates on two AA batteries. When the batteries become depleted, the sensor will automatically send out an alert, so users can replace the batteries when no water is present.
