IMS-4830 Water Sensor with 10 Ft Rope Sensaphone Water Sensor with 10' Rope for IMS-4000 protects your server and equipment from damaging water leaks from malfunctioning HVAC systems, cafeteria accidents, or any general plumbing failures in your facilities. The IMS-4830 is powered directly by the IMS-4000 unit. Note: FGD sensors, accessories, etc. are not compatible with IMS-4000 systems After mounting the sensor, attach the included Water Rope, and simply lay its orange cable around your equipment, place it on the floor or beneath a raised floor, inside a drop-ceiling or in the rafters between floors and anywhere you must know about water near your equipment. You can attach additional Water Detection sensors to each other to expand your water leak detection capabilities throughout your facility; alternatively, IMS Water Ropes are designed to plug into each other to widen your perimeter for any individual sensor.
