MDT
Leak Detection Transceiver
Standard and MAX Range Systems
Product Overview
The Leak Detection MDT helps property owners monitor for water leaks near hot water tanks, under sinks, boiler/basement room floors, or anywhere that water could flood or damage the property. When water is detected, a message is immediately sent to the DCAP, which then generates an alert via email for quick action to mitigate the damage.
The Leak Detection MDT is based on our display MDT board that has an audio jack port for the two-foot-long water sensing cable. Place one end on the ground where water might pool and the other end’s audio jack in the MDT. Longer cable lengths are available. Since the MDT is based on our MDT plastic it too can be mounted on a wall with a #6 drywall screw. The MDT comes with two AA Lithium batteries and has a typical battery life of over 6-8 years.
The Leak Detection MDT comes in two versions, our Standard and MAX Range. The Standard Range is our original, first generation system, which we continue to fully support and maintain.
