I have a MS16A setup to turn on a few x10 light switches. Up until today it would turn them on until a minute after motion stopped then turn them off. Now today suddenly when it detects motion its turning them on and then never turns them off. Trying to figure out why that might be. I've only had this setup for a few days now. I know the rr501 gets the off command from it by manually hitting the Off button under the battery compartment. And the dial or w/e that's on the sensor that sets the delay after motion stops hasn't been touched.
Any thoughts as to why the lights are never getting turned off?
After MS16A turns ON the lights, with out moving the MS16Aor moving in front of it, watch it to see if the red LED blinks, indicating transmission of the OFF signal. If the LED blinks but the light doesn't extinguish, Mr Kramer is probably correct in thinking (new) noise is preventing the OFF signal from getting through (what is being turned ON, CFLs?). If you do not see the LED blink one minute after the light was turned ON, try using the OFF button on the MS16A. If the light now turns off, try: 1. reprogramming the delay period...if you left it defaulted to one minute, try reprogramming to something greater to see if it begins to work. 2. try replacing the batteries. After that I'm out of ideas.
