Description

PERIFELD-M system stays the best volumetric detection system on the market. It provides a level of security never reached and provides a very low rate of false alarms. PERIFELD-M reliability assigned to a low cost of maintenance makes a logical choice in order to increase the safety level of your sites.

PERIFELD-M system is actually considered as the best perimeter protection alarm system for the installation of high safety worldwide. PERIFELD-M system provides the highest level of security with a very low rate of false alarms compared to other volumetric systems. In France the first test of PERIFELD-M started in 1990 in response to customer security site needs and constraints. The PERIFELD-M has been successfully tested by the Air Force and the CEA (“Commissariat à l’Energie Atomique et aux Energies Alternatives”) during more than 12 months. PERIFELD-M system is referred in United States; it is installed in over 40% of nuclear plants. Preliminary tests were conducted by one of the leading operator’s nuclear reactors in the Midwest. In this study, another microwave detection system has been installed in parallel for comparison by the operator. During the test period, lasting 18 months, PERIFELD-M system underwent harsh weather conditions including two very cold winters with snow.

Test results showed a significant difference between the two systems. During 18 months of operation, PERIFELD-M system had no day of downtime while the other system was available less than 90% of the time and exposed to very high nuisance alarm rates.
