This format is designed to fit under most PTAC units and wrap around water heaters when cut in half.
After cutting “bridges” 1 and 2, regions “A” and “B” can be monitored separately by connecting the leads from “a” and “b” connection bridges into separate wireless modules. In this way, the amount of fluid covering the membrane can be determined by the number of regions that are alarming.
The design can be cut in half to create two 3”x30” membranes to wrap around opposing sides of a water heater . Each half should be connected to a wireless module.
Installing the membrane upside-down - with the conductive side facing up - desensitizes the sensor to leaks. If the leak sensor is triggered by accidental exposure to small amounts of liquid (ice cubes falling on the floor and melting under the membrane), this orientation ensures that there must be a significant amount of water to trigger while avoiding the false alarms.
