The Servoteknikk DOS3 (N1115) is a low profile conventional optical Smoke Detector designed to combine optimal response to smoke with a strong immunity to false and unwanted alarms. The sensor employs an alarm verification function which requires two successive pulses before an alarm is given.
The Servoteknikk DOS3 Smoke Detector design provides strong immunity to air velocities, contamination and EMC. By means of a special protective mesh it is ensured that smoke can enter the detector easily whilst accessibility to insects and airborne contaminants is eliminated. The DOS3 Smoke Detector can be mounted on Bases for use in both dry spaces and in difficult environments.
