摘要
The scattered-light system (7-9) and the ionisation system (12, 13) are arranged in the same plane on a common base plate (1). The measurement volumes of the scattered-light system and of the ionisation system are located on both sides of the central axis of the chamber. In addition, a temperature sensor can then be arranged on the central axis. As a result of suitable structural measures, it is achieved that despite the eccentric position of the measurement volumes of the scattered-light system and of the ionisation system the sensitivity of the fire detector remains constant largely independently of the incoming-flow direction of the air.
