Description
CONSILIUM
SALWICO NS-AOS
OPTICAL SMOKE DETECTOR HEAD
PART NUMBER: N11111
24V DC
0.2MA NORMAL
2.5MA ALARM
The Consilium Salwico NS-AOS is an optical smoke detector head designed for integration into marine fire alarm systems. Using optical detection technology, it identifies the presence of smoke by measuring changes in light scatter within the sensing chamber, enabling early-stage fire detection before conditions escalate. Mounted at cabin, corridor, machinery space, or accommodation zone level, this detector forms a critical part of a vessel’s fixed fire detection network, contributing directly to onboard life safety and SOLAS compliance requirements.
Key Features
✓ Optical smoke detection principle provides reliable early warning by sensing smoke particulates through light scatter technology, minimising false alarms from dust or steam in typical marine environments.
✓ Operating at 24V DC with a normal standby current of 0.2mA and an alarm current of 2.5mA, the detector is engineered for low-power continuous monitoring within a loop-based fire detection circuit.
✓ Designed for compatibility with Consilium Salwico fire alarm control panels and detection loop systems; specific panel compatibility should be confirmed against the vessel’s installed system configuration.
✓ Suitable for installation in accommodation spaces, corridors, and other protected areas onboard; mounting location and environmental suitability should be verified against the applicable fire detection system design.
✓ As a direct replacement detector head carrying part number N11111, it supports straightforward like-for-like substitution during planned maintenance or emergency repair of the Salwico fire alarm system.
Marine Applications
✓ Accommodation and cabin zones on merchant vessels, passenger ships, and ferries where continuous smoke monitoring is mandated under SOLAS fire safety regulations.
✓ Corridors, stairwells, and public spaces on cruise ships and ro-ro passenger vessels requiring comprehensive fire detection coverage across multiple detection zones.
✓ Control rooms, switchboard rooms, and enclosed operational spaces on offshore platforms, FPSOs, and support vessels where early fire detection is critical to personnel safety.
✓ Replacement and maintenance applications on vessels with existing Consilium Salwico NS-AOS fire detection installations, ensuring continuity of certified system performance.
✓ Naval auxiliaries, research vessels, and specialised marine units operating fire alarm systems requiring low-current, loop-compatible optical detection devices.
