Security device with built-in intercommunicated false alarm reduction control

A security device, comprising:

• a control center adapted for connecting to a local warning system;
• a plurality of security detectors, which is electrically connected to said control center to intercommunicate with each other, installed at a plurality of detecting areas respectively, wherein each of said security detectors comprises an intercommunicated false alarm reduction control comprising:
• first means for verifying a single zone verification time of said respective security detector, wherein said single zone verification time is a single senor time delay for delaying an activation of the local warning system while said respective security detector is triggered;
• and
• second means for verifying a multiple zone verification time with another said security detector corresponding to a distance between said two security detectors at two different detecting areas, wherein said multiple zone verification time is a multiple senor time delay for delaying said activation of the local warning system while said two security detectors at two different detecting areas are triggered, wherein said multiple zone verification time is longer than said single zone verification time;
• wherein when one of said security detectors detects at least two triggered signals in said respective detecting area within said single zone verification time, said respective security detector activates the control center for activating said local warning system to produce a local warning signal;
• wherein when said two security detectors are intercommunicated with each other to detect two triggered signals in said detecting areas respectively within said multiple zone verification time, at least one of said security detectors activates said control center for activating said local warning system to produce said local warning signal.
