Detection of fire and true alarm is the first duty of fire equipment. Detection is based on fire specifications such as smoke, heat, flame and emitted gases automatically or by residents manually and alarm will be done through sound, light or recorded voice.
Note1: Some of fire detection and alarm equipment work independently and some are parts of a system and cannot have the necessary function alone.
Note2: Fire detection and alarm system components based on technologies are available in different types:
- Conventional Equipment
- Addressable Equipment
- Addressable Intelligent Equipment.
Fire detection & alarm components (basic):
1- Fire control panels:
