Consilium Salwico DOS-3 Optical Smoke Detector N1115

The Salwico Dos3 N1115 is a low profile, conventional, optical smoke detector that is designed to combine optimal response to smoke with a strong immunity to false and unwanted alarms.

Consilium Salwico DOS-3 Optical Smoke Detector (N1115)

The Consilium Salwico DOS-3 (N1115) delivers fast and reliable smoke detection while maintaining a high level of immunity to false and unwanted alarms. Designed as a low-profile conventional optical smoke detector, it provides dependable fire detection for marine, offshore, industrial, and commercial applications.

Furthermore, the DOS-3 incorporates an intelligent alarm verification function that requires two successive detection pulses before initiating an alarm. As a result, the detector reduces the risk of nuisance alarms while maintaining a rapid response to genuine fire conditions.

The DOS-3 also offers excellent resistance to air movement, contamination, and electromagnetic interference (EMC). In addition, a specially designed protective mesh allows smoke to enter the sensing chamber freely while preventing insects and airborne contaminants from reaching the detector. Consequently, the detector maintains reliable performance and reduces maintenance requirements.

Engineers can install the N1115 on detector bases suitable for both dry spaces and harsh environmental conditions, providing greater flexibility across a wide range of applications. The DOS-3 is also fully compatible with the Salwico OD-5 smoke detector, simplifying system upgrades and replacements.
