The Consilium Salwico DOS3 (Part No. N1115) is an optical smoke detector supplied complete with its mounting base, designed for integration into marine fire alarm systems. Operating on a light-scattering detection principle, it identifies the presence of smoke particles in the monitored space and triggers an alarm signal to the connected fire detection panel. Suitable for a wide range of shipboard spaces, this detector plays a critical role in early fire warning, supporting crew safety and regulatory compliance across commercial and passenger vessel applications.
Key Features
✓ Optical smoke detection with a 16–32V DC supply range, monitoring current of 40µA, and alarm current limited to 55mA max, ensuring compatibility with standard marine loop configurations.
✓ Auxiliary output limited to 20mA at 6V, allowing integration with secondary indication or control devices within the fire alarm system where required.
✓ Certified to EN54-7:2000, confirming conformance with the European standard for point-type smoke detectors using scattered light, transmitted light, or ionisation principles.
✓ Rated for ambient temperatures from -25°C to +70°C, making it suitable for installation in a broad range of shipboard environments including accommodation, machinery spaces, and service areas.
✓ Supplied with detector base included, supporting direct replacement or new installation without the need for separate base procurement; mounting configuration is subject to confirmation against the specific panel and loop design.
Marine Applications
✓ Accommodation and cabin areas on passenger ferries, cruise ships, and ro-ro vessels where continuous smoke monitoring is required under SOLAS fire detection regulations.
✓ Engine control rooms and auxiliary machinery spaces on cargo vessels, tankers, and offshore support vessels requiring reliable early warning detection.
✓ Galley surrounds, corridor spaces, and service passages where optical detection is preferred for sensitivity to slow-smouldering fire conditions.
✓ Integration into Consilium Salwico fire alarm and detection systems onboard vessels already equipped with compatible loop-based panels and detection networks.
✓ Refit and maintenance programmes requiring like-for-like replacement of existing DOS3 detectors to maintain system integrity and certification status.
