Fixed-site nuclear facilities are required to have a continuously manned central alarm station and a secondary alarm station.
Abstract
All security alarms are required to annunciate at each alarm station such that a single act cannot remove the capability of calling for assistance. This report reviews various types of intrusion detectors, signal transmission methods, and receiver units relative to establishing the required intrusion alarm system's independence and redundancy. Illustrations, a glossary, and a sample data sheet are provided. (Author abstract modified)
