ION FIRE ALARM SENSOR AND ITS APPLICATION IN AIRCRAFT FIRE ALARM SIGNALLING SYSTEM

摘要

The ion fire alarm sensor is widely used in aircraft fire alarm system. Its advantages are long service life and stable operating performance. This paper gives the application of ion type fire alarm sensor in aircraft fire alarm signalling system. The first, it introduced the basic operating principle of ion fire alarm sensor. The second, it gave the operating circuit of ion type fire alarm signalling system. At the last, it gave the functions of main elements in the system.
