CONSILIUM MARINE
ZENER BARRIER ISOLATOR
SALWICO ES-2K
PART NO. 46460
The Consilium Salwico ES-2K Zener Barrier Isolator (Part No. 46460) is a precision intrinsic safety component designed to isolate and limit electrical energy within fire alarm system circuits aboard commercial and naval vessels. Zener barriers of this type serve as a critical interface between safe-area control equipment and field-mounted detectors or sensors located in potentially hazardous zones, ensuring that fault currents and voltage spikes cannot propagate across the boundary. As part of the Salwico fire detection infrastructure, this isolator plays a foundational role in maintaining system integrity, crew safety, and regulatory compliance across the vessel’s fire alarm network.
Key Features
✓ Functions as a Zener-diode based barrier to limit voltage and current entering hazardous-area circuits, providing intrinsic safety isolation within fire alarm loops.
✓ Specific electrical ratings including voltage, current, and resistance parameters are subject to confirmation against the original Consilium Salwico ES-2K system documentation and configuration.
✓ Designed for compatibility with the Consilium Salwico ES-2K fire detection and alarm system; suitability for other panels or loop configurations should be verified prior to installation.
✓ Typically installed in the safe-area control cabinet or marshalling panel, providing a fixed mounting point between the fire alarm control panel and field wiring runs throughout the vessel.
✓ Replacement of Zener barrier isolators is a routine service activity during scheduled maintenance or after fault diagnosis; genuine part numbers such as 46460 ensure correct fit and system certification continuity.
Marine Applications
✓ Installed aboard cargo vessels, bulk carriers, and tankers where fire detection loops interface with hazardous or classified zones requiring intrinsic safety separation.
✓ Used within passenger ship fire alarm systems where SOLAS-compliant detection networks demand reliable signal isolation at every field circuit boundary.
✓ Applied in offshore support vessels and platform supply vessels operating fire alarm systems in areas with potential flammable atmosphere exposure.
✓ Suitable for naval auxiliaries and government vessels operating Consilium Salwico fire detection equipment requiring original manufacturer components during refit or repair.
✓ Utilised during drydock refits and planned maintenance periods when fire alarm system components are inspected, tested, and replaced to maintain class certification.
