I have an ADT Safewatch Plus RF system and am having an issue with one of the motion sensors (Detection Systems model #60-511). The unit detects a low battery, followed by failure every 1-2 months after battery replacement. None of the other sensors, including the other motions, are having problems and batteries last for years.
ADT says they'll come out, but it'll cost me. Does anyone have any advice, including perhaps removing the sensor from the system? Any help would be greatly appreciated.
