I have had an older 2420 Motion Detector (one without the two sensitivity dials inside) for some time and it has worked flawlessly. I noticed it one day not responding and found the battery was low, about 6volts. I received no low battery indication as I had programmed. I replaced the battery, and changed nothing else, and now I have issues.
Jumper 4 is the only one set to produce an ON only command.
The detector when inside at my desk works as desired. When placed in its rightful place, my garage, the LED does not flash, but Indigo reports about 1/3 of activity (allowing for delay). However if I press the set button Indigo does report the on or off command perfectly..
Not sure where to go with this.
