ABSTRACT:
In order to enhance the process of reducing motion-type false alarm of security alarm system, a multiple time-setting adjustment control is employed in the process of reducing motion-type false alarm of security alarm system automatically or manually, wherein a cross zone delaying period during the verification condition for a second detecting signal from another motion sensor is set to have a longer time period than a single zone delaying period during the verification condition for a second detecting signal from the same motion sensor, so as to further effectively reduce the motion-type false alarm possibility without reducing the protection performance of the security alarm system.
