Expert Reply:
Hi Robert; do you have a TST system like the # TST-507-RV-4-C? How old are the sensors? The # TST-507-RV-S4 sensors have a battery life of 12-18 months so it sounds like it might be time to replace the sensor if it is no longer detected. They are also sold in pairs # TST-507-RV-S2.
If it is an actual internal sensor like # TST-507-INT-S1 the battery life can last up to 4 years depending on use so it is less likely that the battery gave out unless it is old compared to the other sensors. If this sensor is within the 3-year warranty period I would reach out to TST and see if they will send you a replacement.
