We recently discovered a problem with the INSTEON Water Leak Sensor 2852-222. Water Leak Sensors with Firmware Version 41 can report a "Dry" condition instead of "Wet" when exposed to water. The problem has been reported to INSTEON and has been resolved with a new firmware load, however, the new firmware is not user upgradeable. We recommend that all 2852 Leak Sensors be tested immediately to assure proper operation.
To test for proper operation, place the Leak Sensor on a wet sponge, or towel. Your automation controller should report a wet condition. Remove the Leak Sensor from the wet surface and tap the SET Buttons to reset the sensor. If your 2852 Leak Sensor fails to perform as indicated, contact INSTEON Support at 1-800-762-7846 or your INSTEON Dealer for further instructions.
