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.
