Aspirating Smoke Detector System
What is Aspirating Smoke Detector System?
ASDs are very early smoke detectors that use a powerful fan to draw air through a network of pipes and into a detection chamber. Smoke particles are detected by this system, and if the concentration reaches a predetermined level, an alarm is triggered. Aspirating smoke detectors are often installed in large buildings, such as airports, office buildings, and hotels, when traditional smoke detectors are not feasible or when fire detection and mitigation are necessary to prevent damage caused by the loss of life and assets involved in a fire. Additionally, they are used in environments prone to smoke contamination, such as cleanrooms and laboratories.
Why ASD?
There are some shortcomings of common smoke detectors that cause alerts when false smoke is detected. Like other smoke detectors, ASD does some smart work and is built differently than other common smoke detectors. For avoiding false alarms, air samples captured by an Aspirating Smoke Detector are filtered and containments are removed.
In contrast to passive smoke detection systems such as spot detectors, smoke is drawn to the detector by bore holes in piping running through the protected area. When a threat is detected to the Aspirating Smoke Detector system’s ability to detect smoke, an alarm can be raised. In contrast, passive devices are usually only electrically monitored, without a way to determine whether smoke reaches the sensor.
