My PG9984P motion sensor has been giving me a low battery warning for a while. I replaced the battery with a Panasonic CR123.
The current battery voltage measured while in the sensor holds around 2.9V. The low battery threshold voltage is 2.5V. Is this the point at which the sensor is supposed to register low voltage or the limit at which the sensor will no longer function?? If the latter, at which point does the sensor register low battery warning? <3.0V ??
The sensor is still functioning but the warning may be a bit premature.
