N11891 short circuit isolator is a dedicated loop protection module for Consilium Salwico marine fire alarm systems. Installed on each fire detection zone loop, it automatically isolates the faulty circuit segment once a short circuit occurs, ensuring all other normal zones remain functional without full system shutdown. Equipped with transparent sealed enclosure and double cable glands for marine salt fog and moisture resistance, it supports manual zone and address marking on the label plate. Widely deployed on cargo ships, container vessels and offshore platforms to enhance the stability and safety of ship fire detection networks, fully compliant with marine SOLAS fire safety standards
