Replacement Motion Sensor Heads

I would recommend the H-Z units sold by

In Addition to what RBM said, you could go to an electrical supply company to get a different brand. I have been using the Rab brand for a few years now. They cost around $60.00.

Thanks for these tips!

Of those two the Heath/Zenith is the best. I have about 20 around the house of various brands and styles, inside and out. The Heaths hold up fairly well if you keep them out of the sun. Direct sun will kill any of them. The Regents are pure crap. I have some a few months old that you have to do gynmastics in front of to get them to light.

I second this recommendation for Heath: we've got one outside on the garage facing north that doesn't get direct sun, and it's pretty old. It must be at least 11 years old and works just great, very responsive to motion.

I am experimenting with a sunvisor over my south facing detectorrs that seems tio extend the life, I glued a PVC strip cut off of some old verticle blinds about 3" long over the head to shade it.

Ok. I'm gonna go out and see if I can find one of those Heath-Zeneth by Granger or a Rab brand. They're kind of expensive but hopefully they won't turn on when I turn off other switches in my house!

Hmmm, I have an El Cheapo in my garage which is ~14 years old. It has adjustment for sensitivity, time delay to go off. I screwed in two LED lamps. This thing will last LONG time. Only thing I hate about this thing is it comes on and stays on if power fail. occurs, I have to turn the breaker feeding it off/on to reset it.

If you have electrical problems that cause "dips" in the line you will get false trips ... on any detector.

What exactly is a dip and what would cause it? How can I check for them?

Low voltage fluctuations. Here is a link to the H-Z models sold by Grainger.

Ok. Thanks. I ordered one and will see what happens.

I received the Grainger version of the H-Z replacement sensor. It solved my problem. With the Regent sensor, if I operated my garage light switch or my laundry room light switch, the motion light went on. With the H-Z, they don't go on. Thanks again!
