    How do window sensors work?

    Security Specialists

    Could you let me know how a window sensor works for an alarm system? How can I ensure it will be well maintained?

    "There are generally two types of window sensors,

    1 - vibration sensor- will trigger an alarm upon breaking the glass

    2- contact sensor - when the window is opened it will trigger an alarm"

    "There are two different types. There are contacts, so they will change state when the window is opened or closed with physical movement. Then there are shock sensors that will sense if the window has been smashed or has been hit with force."

    "Hi Pete,

    So a window sensor works like this:

    Glass break detectors complement door and window sensors by monitoring sound or vibration. When they detect the frequency of shock waves associated with glass shattering, they sound an alarm.

    To make sure it is well maintained, it is recommended by us engineers that we service the system once a year to make sure everything is as it should be. If you have any concerns or issues prior to the service, then, by all means, we can have a look at the system as a problem arises."
