User Manual

The larger part of the sensor is usually placed on the door or window frame, and the smaller magnet placed on
the door or window itself; the two parts must be parallel to each other, and as close to touching as you can
place them, without stopping the moving part from opening smoothly. Each part of the sensor has a pair of
little lines on one side; you should install the sensor with those sides with the little lines next to each other.
This is illustrated in the bottom half of this page. Try to leave at least a centimetre or so of empty space at
either end of the Door/Window Sensor.

If you have UPVC windows or other windows with bevelled or angled edges click here.
You should also try to follow our general Accessory positioning guidelines.
If you are having problems positioning it, try reading our help on positioning.
I can't see a flashing light on it
The light, when flashing, is in the position of the green dot here:
When you first put the battery in, you should expect to see the Door/Window Sensor light blink twice every
few seconds; the light will go out once the Door/Window Sensor is communicating with the Hub. The light will
come on again when this Door/Window Sensor is selected for placement on the website; then, it will flash
regularly once a second (if it is in a good position for the Accessory to be installed), or it will blink twice every
few seconds (if it is not in a good position). If you aren't placing this Door/Window Sensor, it most likely will
not be flashing its light.
How do I stick it up?
Firstly, make sure you know how to use the sticky pads! If you haven't already read the instructions for these,
do so now here.
Peel a sticky pad off the backing sheet, put it onto the back of the Door/Window Sensor and press firmly for a
few seconds. Then, peel off the printed part of the cover sheet off the pad you just stuck down, and press the
Door/Window Sensor against the surface you want to stick it to firmly for a few seconds. If you like, you can
use two sticky pads, one at either end of the sensor.
For the magnet we supply special, small sticky pads, which you use in the same way as the big ones.

What does the flashing light mean whilst I'm installing it?
When this Door/Window Sensor is selected for placement on the website it will flash regularly once a second
(whilst it is in a good position for the Accessory to be installed), or it will blink twice every few seconds (if it is
not in a good position).
