EV-DW4917- DSC Wireless Recessed Door/Window Contact

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.

Anonymous User on 9/12/2009, said: Overall I give it a good rating. It disappears nicely and was pretty easy to install. The instructions call for an 11/16" drill bit but I found a 3/4" Auger bit did the best. I installed 3 of these and the 3/4 auger made a perfect size hole for the sensor. For the magnets I had to use some plumbers teflon tape to get it to fit snugly on two of the three. But I found it easer to use the teflon tape than to try to file/sand the 11/16" hole bigger like the manual suggests. You should be very careful with the little circuit board when removing it to change the battery. I think I accidentally broke a leg on one of the little circuits on the board when doing this. Luckily I have a friend who is really good with solder! Was this comment helpful? yes no   (0 people found this comment helpful, 0 did not) 2. Greg on 4/17/2007, said: Works great!

It vanishes after installation, range covered all my doors, very easy to install using a paddle bit. Response is instant to control unit. If battery lasts 3 years (says up to 5 in the manual) that would be awesome too. Was this comment helpful? yes no   (3 people found this comment helpful, 0 did not) Showing comments 1-3 of 3
