GUIDELINES ARE GIVEN FOR DESIGNING AN INTRUSION ALARM SYSTEM TO MEET THE NEEDS OF AN INDIVIDUAL FACILITY. SINGLE ZONE AND MULTIPLE ZONE MONITORING ARE EXPLAINED AND PRECAUTIONS AGAINST FALSE ALARMS ARE REVIEWED.
Abstract
SECURITY SYSTEMS ARE HIGHLY INDIVIDUAL AND NO TWO FACILITIES CAN BE PROPERLY PROTECTED BY EXACTLY THE SAME SYSTEM. DESIGN CRITERIA ARE GIVEN WHICH TAKE INTO ACCOUNT POSSIBLE THREATS TO FACILITY SECURITY, TYPE OF ALARM MONITORING SYSTEM, VALUE OF COMMODITIES TO BE PROTECTED, AND DESIGN AND CONSTRUCTION OF THE FACILITY. AREAS WHICH NEED PROTECTION SHOULD BE IDENTIFIED AND THEN SEPARATED INTO ZONES WHICH CAN BE EITHER INDIVIDUALLY OR JOINTLY MONITORED AT SOME CENTRAL POINT. THE SETTING UP OF INDIVIDUAL ZONES AND THE DESIGNING OF AN APPROPRIATE SYSTEM TO MONITOR THESE ZONES IS COVERED BRIEFLY. THE FINAL SECTION COVERS SELECTING AND LOCATING SENSORS. PARTICULAR ATTENTION IS GIVEN TO LOCATIONS FOR MOTION SENSORS, ENERGY SENSORS, AND MICROWAVE DETECTION SYSTEMS WHICH REDUCE RISK OF FALSE ALARMS. THE LIMITATIONS OF A DETECTION SYSTEM ARE POINTED OUT; INTRUSION DETECTORS WILL ONLY DETECT, NOT PREVENT, INTRUSION. FOR PART 1, SEE NCJ-560780. (GLR)
