Salwico NS-AOHS-EXN Multisensor (N11255)

The Consilium Salwico NS-AOHS-EXN (N11255) is an analogue addressable dual optical smoke and heat detector designed for use in wet and challenging environments. With an IP55 protection rating, it provides reliable fire detection in areas where moisture, humidity, or dust may be present while keeping dependable performance.

The detector continuously monitors its surroundings using two independent sensing technologies. An optical smoke sensing element quickly detects smoke particles generated by developing fires, while an integrated heat sensing element monitors temperature changes and responds to higher heat levels. By combining smoke and heat detection in a single device, the NS-AOHS-EXN enhances fire detection reliability and helps identify a wider range of fire conditions.

When the detector identifies an alarm condition, it immediately activates its red LED indicator, enabling personnel to quickly locate the source of the alarm. The LED remains lit until the fire alarm control panel resets the alarm, making sure the activated detectors can be easily identified during emergency response and maintenance activities.
