The Consilium Salwico NS-AOHS-IS (Part No. N11250) is an intrinsically safe analogue-addressable optical smoke and heat multisensor detector for Salwico fire alarm systems. It combines independent optical smoke and heat sensing elements and is intended for hazardous areas where Ex/IS-certified fire detection is required.
Key Features
- Combined optical smoke and heat detection in one addressable detector.
- Two independent analogue sensing elements: infrared optical smoke sensor and thermistor heat sensor.
- Intrinsically safe design for hazardous/explosive atmospheres.
- Red LED provides local alarm indication and remains illuminated until the fire alarm panel resets the alarm.
- Detector address is configured using a DIP switch on the rear.
- Connected to the fire detection loop through an ISOLATOR-A (N1790).
- Up to 20 intrinsically safe addressable IS units can be connected to one ISOLATOR-A.
- Individual smoke or heat sensing can be temporarily disabled according to system configuration.
- Remote LED indicator connection is not supported.
Typical Applications
- Marine and shipboard hazardous areas
- Offshore oil & gas installations
- Tankers and cargo vessels
- Engine rooms and machinery spaces requiring intrinsically safe detection
- Fuel and gas-handling areas
- Hazardous-area fire detection systems
- Salwico CS3000, CS4000, NSAC-1 and compatible marine fire alarm systems.
