What is it?
The Door/Window Sensor detects whether a door, window, or other thing is Open or Closed, as part of the
AlertMe Intruder Alarm system. As well as alerting you to intruders, this checks that you've shut all your doors
and windows before going out! The Door/Window Sensor is battery powered and looks like this:
The big part is the main sensor, and the little part is a magnet. It works by detecting if the two parts are very
close together (meaning the door, or window, is shut), or far apart (meaning it is open!). There's more info
here.
How do I start it up?
To put in a battery, squeeze the tabs on opposite sides of the big part of the sensor, and lift off the front (see
here for pictures or here for a movie). The battery is supplied by AlertMe in the Door/Window Sensor box. Clip
the back on the sensor again when you have put the battery in. The light should then blink twice every few
seconds for a while; this will stop once the Door/Window Sensor is communicating with the Hub. If the light
does not turn on at all, then click here for help.
If it stops flashing, but does not appear on the website as an icon, wait a few minutes. If that doesn't work, try
taking the battery out for 10 seconds, replacing it, and waiting another few minutes. If it still doesn't appear,
click here.
Where should I put it?
The Door/Window Sensor detects whether a door, window, or other thing is Open or Closed. The sensor has
two parts - a larger part, into which the battery is placed, and a smaller part (which is actually a magnet). The
Door/Window Sensor is designed for use indoors but it can be used on external windows or doors, providing
that the larger part is normally indoors. You can use the Door/Window Sensor to check whether ground floor
exterior doors and large windows are open or closed (especially helpful when combined with AlertMe's
warning if you leave your home set to "Away" without closing everything!).
