Abstract :
The authors discuss concepts used in developing the CSC (Correctional Services Canada) Duress Alarm Location System (DALS). A block diagram and theory of operation for the system are presented. A sample data and test results for an actual test installation are presented and analyzed. It is concluded that the DALS is able to acknowledge and locate a duress alarm within an indoor environment with useful precision and reliability
