Survey of secure alarm communication systems

Technical Report ·
OSTI ID:7094490

The results of a broad survey of techniques for providing secure communication links for alarm signals are presented. Categories of security techniques are defined and include both protective systems and a number of supervisory techniques ranging from simple DC supervision to digital dialog operation with random encoding. Considerations which are specific to the particular application of installation are also discussed. An extensive annotated bibliography is included.
