Hidden discreetly within the frame of a door, the wireless recessed door transmitter (EV-DW4917) is powered by a replaceable lithium battery that provides uninterrupted supervised security for many years. Once installed, the only visible part of the transmitter is the access cap (available in white or brown). Access caps are either flanged or non-flanged and allow for either a screw-mount or a press-fit installation. A flat head screwdriver is used to change the cap if needed or access the battery. Primarily designed for installation within a door, the transmitter can also be used within the frames of windows. Dimensions: 3/4 Inch Diameter & 2 1/2 Inches Long.

I am confused by some of the negative reviews. I followed the instructions. I used an 11/16" x 6" bit (not a paddle bit) as instructed. Then I carefully put pressure on the drill in a circular motion while moving it in and out (you know reaming it out, not wobbling it out). Testing the hole often by trying to insert the sensor. That quickly gave me a fit that allowed insertion and removal. Yes I had to countersink the magnet slightly, but that kind of adjustment would be normal in any installation of just about anything short of the space program. I have about 25 of these units installed and to date, after 5 years, they are still working perfectly with no failures. I did change the batteries about 6 months ago even though they had not failed. I believe the success was mostly due to the $39.00 bit and patience.

The manufacturer recommends an 11/16" hole, then "routing it out" until you get a snug fit for the body of the sensor. I used a dremel with a sandpaper cylinder to widen it a little. The body got stuck halfway in and I was unable to remove it without destroying it. It might be possible to use the sensor without the plastic body but in trying to wedge it in, a delicately-soldered capacitor on the circuit board came off. So that's $36 in the garbage. I bought another one since I already had a hole in my door. I widened it with a 23/32" drill bit from Amazon and it worked perfectly. A 3/4" bit would work too with some adhesive in the hole. The side with the magnet sticks out a hair due to a flanged top, maybe 1/16" to 1/8". If your door is very tight-fitting, start by drilling a shallow flat hole to set the flange in. I think a 13/16" spade bit would be perfect for that. Then continue with the 23/32". It was a pain. The two stars is for incorrect instructions that led to the product's destruction. The second one is working perfectly and were it not for the installation boondoggle this would be a four-star review.

After installed, it works great. I tested it first before installation in case there was a problem with the sensor or installation. I tested the battery and it was fresh in the package. Similar comments to others. The instructions say to use drill a 11/16" hole and widen it a bit for fit. This only worked with the magnet. For the sensor I first bored a 11/16" hole with a spade bit then had to widen it a little with a 3/4" bit. The sensor fit was then good. It would appear the sensor was incorrectly manufactured a bit wide. Also the magnet sticks out about an 1/8". I had to recess the sensor for the door to close. I suggest not drilling the sensor hole too deep so you can get a good fit. I just installed it so I can't comment on reliability or battery life.

The instructions say bore a 11/16" hole. Don't do what I did and try to force it in; I broke mine. The casing should be made out of metal not plastic. I took the circuit board and battery out and dropped it into the hole. Works fine. Next time I will do what Steven said, use a 3/4" bit.

These are nice in that they are hidden from view once installed. You need both an 11/16 and a 3/4 wood boring spade bit. The instructions say to use an 11/16 one, but you will never be able to fit the sensor in the hole because the sensor is too big. Just use the 3/4 bit to slightly open up the hole made by the 11/16 bit just a tad, and it should be much much easier to install. Don't overdo it with the 3/4 bit, otherwise, the hole will be too large!

A pain to install, as the unit is slightly larger than the 11/16" hole they instruct you to drill. But the sensor is hidden (completely when the door is closed) and works flawlessly.
