  • Aspirative fire detection and / or air monitoring systems of this type are often used for the earliest detection of fires already in their formation phase. They are then also called, for example, smoke aspiration systems, aspirating smoke detectors or active detectors. Typical areas of application are either rooms with high-quality or important facilities, such as rooms with computer systems in banks, insurance or data centers, or the computer equipment itself. For this purpose, the room air or the device cooling constantly representative subsets are removed and at least one serving as a supply pipe system of the detection unit of the aspirative fire detection and / or air monitoring system for detecting a fire characteristic supplied.
