Honeywell Ademco AURORA PIR Motion Sensor...

I have one of these mounted in the kitchen and my keypad is indicating it as being faulty. I would like to test it and see if it is still getting current.

Two questions--

1) How do I get the front cover off? Instructions say just insert a screwdriver in the bottom and twist but that isn't working.

2) If and when I get it off, how do I test for current? I do have a multimeter. Will I just be looking for 12VDC at the pos and neg?

First off, if the keypad says fault it just means it is open or detecting motion. If it says "check" then there is a problem.

They are kind of hard to pop open but you are correct. Should be 12vdc power and 2 data wires. Check for loose connections there and at the panel as well.

The PIR is definitely at fault. I can't set the system without bypassing it.

I can't get the faceplate off for love nor money. Pushing in on that tab and twisting, pulling, etc. accomplishes nothing as far as I can tell. It doesn't even act like it wants to separate.

What is the best way to destructively remove it? I'm going to have to replace the unit anyway I figure. If I drill through the plastic at the bottom of that hole will the tab fall off inside enabling me to remove it?

Those covers can become stubborn with age.

Stubborn isn't the word for it. This thing simply will not come off! Do I insert the blade in the hole or where? How wide does the blade need to be to twist it off?

I'm starting to think the installer glued the thing together so that it couldn't be serviced. This is ridiculous!

Again, is there a simple way to just break the face off?

If you don't care if you break the housing, just take a relatively wide bladed screwdriver and put it in the slot and twist til the two halves separate.

Look carefully at that bottom edge. There is a small set screw that is optional that may have been used.

No set screw I'm afraid--that would explain the difficulty if there were one.

Then you are down to brute force. It's possible someone broke the housing before, and used superglue to put it back together.

Make sure you have a small size straight screwdriver even tho you have to twist it it wont fit a standard size screwdriver. Need about 1/4" or less wide. Just saying...
