HAVERKAMP fence interface®

The HAVERKAMP fence interface was developed for surveillance and for forwarding alarm signals from all HAVERKAMP quiescent current systems. Alarm signals from the fence are galvanically isolated and transmitted to the overriding system through potential-free contacts. Voltage surges of up to 2 kV are filtered out – thus ensuring reliable fence surveillance.

The evaluation unit is able to monitor and evaluate up to 20 detection lines. Potential-free changeover contacts are available for the transmission of alarm signals.
