Trigger Tape is a leak detection device used to interface SMT’s Moisture Detection Sensor (MDS) to third party alarm monitoring control systems or security systems.

The Trigger Tape unit provides a digital 5V output and a dry relay alarm contact indicating the presence of water on the Moisture Detection Sensor.


The Moisture Detection Sensor comes in copper and stainless steel versions and is equipped with an adhesive backing allowing it to be easily adhered to any pipe or surface you wish to monitor.


For analog measurements, the MDS can be interfaced to SMT’s A2 and A3 series data loggers.


Price includes 2ft MDS and 6' Leaded Cable.
