Detectors
Dual Technology Detectors - A combination of infrared and low frequency microwave, where both technologies have to be triggered to cause an alarm. These are used in unstable areas such as factories and garages.
Passive Infrared – detect movement of infrared energy in a room or area, opening a relay sending an alarm condition to the control panel.
Pet Friendly Detectors - Again a combination of infrared and microwave detectors that ignore smaller signals and can distinguish human shape and movement from cats and dogs in the home.
Glass Break Detectors - A microphone that listens for frequencies similar to the sound of breaking glass and are usually mounted on the ceiling close to glass panels.

Reed Switches
A magnetic switch composing of two halves, one fixed to frame of the door or window and the other fixed to the opening door or window panel.
When the magnetic field is broken an alarm will result. There are many types of reed switches available for homes and commercial sites.
Factories and other commercial buildings often use a combination of surface or concealed reed switches, along with more heavy duty switches for their roller doors and factory doors.
Vibration Detectors
Small devices attached to glass door or window frames that detect shock waves created when glass is attacked.
For double the protection a combination of reed switch and vibration detectors can be fitted to glass doors or windows.
