Title:
DOOR/WINDOW MAGNETIC SENSING DEVICE AND METHOD OF INSTALLING
Document Type and Number:
WIPO Patent Application WO/2017/117397
Kind Code:
A3
Abstract:
A door/window magnetic sensing device includes a housing, a magnetic sensor disposed in the housing and configured to sense signal strength of a magnet and output a signal strength value, and a controller for receiving a signal strength value from the magnetic sensor. The controller is configured to compare the signal strength value to an alarm threshold value and output one of a normal state signal and an alarm state signal. Further, a tamper state is detected from the approach of a second magnet. An indicator assists in mounting the door/window magnetic sensing device and mounting a magnet assembly.
