With its patented lint filter, it suppresses even the finest dust particles that would otherwise falsify the detection process. Thanks to its optimised aerodynamic measuring chamber, the smoke sensor is also immune to dust deposits. This means that there is little chance of false alarms. Up to five alarm levels can be programmed within the sensitivity range of 0.002%/m to 10%/m. You can then rest assured that individual measures can be taken for each monitored zone. With dangers and hazards detected this precisely, any necessary alarm response is focused and extremely swift. SEC-ASD-533 One channel Basic Display SEC-ASD-531 • Alarm sensitivity from 0.002%/m (measurement resolution < 0.001%/m) • Scattered light technology with high power LED • As sensitive as a laser – but with a longer service life and a greater temperature range • Up to five alarm levels for environment-based detection • Maximum protection against false alarms SEC-ASD-532 One channel Advanced Display In terms of smoke concentration, the alarm sensitivity of the HD (high dynamic) smoke sensor ranges from 0.002%/m to 10%/m. This is equivalent to the sensitivity spectrum of a laser based detector. In the extra large LVSC (large-volume smoke chamber), the sensor permanently analyses the airflow with a high power LED using tried and tested scattered light technology. It meticulously detects even the slightest increases in smoke concentration. Securi ton ASD – because sensitivity counts: One channel Basic Display
