Some of the most vulnerable areas in our homes are our windows and doors. Most home robberies and break-ins involve entry through a window, and while window bars can certainly do the trick when it comes to keeping intruders out, some of us might find them unsightly. These days, there's a wide selection of door and window sensors that detect entry, and Linear's DXT31 door/window transmitter is one of the most reliable on the market.
Measuring a tiny 4 x 2 x 2 inches, Linear's DXT31 door/window transmitter is a sleek and reliable unit that packs a big punch without being an eyesore. The battery powered unit is designed for use with Linear's DX format receivers and uses ingenious magnet-based technology to detect when a window or door is being opened.
How it Works:
A typical installation involves mounting the magnet on the window or door and placing the transmitter on the frame itself. When the window or door is opened, thereby moving the magnet more than 1/2" away from the transmitter, an alarm signal is sent from the transmitter to the receiver. A restore signal is sent when the magnet returns to its proper spot.
External contacts can be wired to the terminal block and will allow the transmitter to send alarms and restores from these contacts. This can include an external glass break detector, which will add an additional layer of security to your home!
