I have multiple PR511s around the house, but two in particular have had "interesting" behavior (1 above the garage, call it F10, and one at the front door, call it F14.)
The idea is that when F10 detects motion, it would go on and, in turn, turn on F14 to light up the path from the driveway to the front door.
When I first installed them, I used lamp wire, but later discovered that it was against code. At the same time, F10 was burning bulbs every few days, so last week, I replaced the wiring with 14.2 (3-way) wire on both units. So far, F10 hasn't burned any bulbs since.
However, when F10 detects motion and turns on F14, F14 never goes off. I have to manually send it an off command. I had thought that it was the wiring, but with this new grounded wire, shouldn't it work?
I've been wondering whether another lamp on the same run may be causing interference, thus my title question.
* If F14 is waiting for F10 to tell it to go off and it's not receiving the signal for whatever reason, I would focus on looking for the interference
* however, if it's supposed to go off after the predetermined time on its control panel (5 min), then I could have a defective PR511?
Note that I obviously power-cycled the devices when I replaced the wiring, so the recommendation from other threads may not be applicable to this situation.
Thanks in advance!
