Abstract:
A process of reducing motion-type false alarm of a security alarm system, which comprises a control panel (CPU), a local warning system electrically connected to the control panel, a plurality of motion sensors which are respectively installed at a plurality of motion detecting areas and electrically connected to the control panel, a dialing system being built in the control panel for transmitting signals to a central station for dispatching to a designated police resource when the dialing system is activated, comprising the steps of:(a) activating the local warning system to produce local warning signal for a designated period of time when one of the motion sensors detects a trigger motion within a respective motion detecting area during a standby condition of the security alarm system;(b) delaying to activate the control panel as well as the dialing system for a first preset time period as a single zone delaying period and at least a second preset time period as a cross zone delaying period which is longer than the single zone delaying period, wherein said security alarm system is in a verification condition during said single zone and cross zone delaying periods;(c) activating the control panel to normally respond by activating the local warning system to produce warning signals and the dialing system to transmit digital signals to the central station when the same motion sensor that detected the trigger motion detects another motion in the same motion detecting area within the single zone delaying period during the verification condition;(d) activating the control panel to normally respond by activating the local warning system to produce warning signals and the phone dialing system to transmit digital signals to the central station when another motion sensor detects another motion in another motion detecting area within the cross zone delaying period during the verification condition; and(e) resetting the security alarm system to the original standby condition when there is no other motion is detected by any motion sensors during the verification condition, wherein the standby security alarm system is ready to enter the verification condition again when there is motion detected by any of the motion sensors again.
