PERFORMANCE CRITERIA AND TEST METHODS FOR MAGNETICALLYACTUATED ELECTRICAL SWITCHES FOR USE IN PROTECTIVE INTRUSION ALARM CIRCUITS.

Abstract

THIS TECHNICAL PUBLICATION DESCRIBES TEST METHODS AND ESTABLISHES PERFORMANCE CRITERIA FOR MAGNETICALLY ACTUATED ELECTRICAL SWITCHES INTENDED FOR USE IN PROTECTIVE INTURSION ALARM CIRCUITS TO MONITOR THE POSITIONS OF DOORS, WINDOWS, ETC. THE SWITCHES INITIATE A SIGNAL TO CAUSE AUXILIARY EQUIPMENT TO SEND AN ALARM TO A POLICE PANEL, CENTRAL STATION, OR A LOCAL AUDIBLE ALARM DEVICE. THIS DOCUMENT CONTAINS REQUIREMENTS AND METHODS OF TEST FOR MATERIALS, PERFORMANCE, AND ELECTRICAL PROPERTIES. SWITCHES COVERED BY THIS STANDARD ARE CLASSIFIED INTO FOUR TYPES BASED ON THEIR INTENDED OPERATING ENVIRONMENT AND TAMPER RESISTANT FEATURES. THE PERFORMANCE CHARACTERISTICS SELECTED ARE THOSE THAT AFFECT THE FALSE ALARM SUSCEPTIBILITY OF THE DEVICE. THIS STANDARD DOES NOT PROVIDE PERFORMANCE CRITERIA FOR RESISTING ATTEMPTS TO DEFEAT THE DEVICE THROUGH PHYSICAL OR SURREPTITIOUS ATTACK. ADDITIONAL MATERIAL INCLUDES ILLUSTRATIONS OF TEST EQUIPMENT, STATISTICAL TEST SCHEDULES, AND TEST FORMULAS. INCLUDED IS A LISTING OF OTHER PUBLICATIONS OF THE LAW ENFORCEMENT STANDARDS PROGRAM.
