Development of Fire
Flashover
Standard situation in fire science
FlashoverPrimary danger: heatPrimary danger: toxic and corrosive smoke
6Siemens Building Technologies Version 1.0 Fire Safety
Ionization Smoke Detector
Ionization detector requires the use of AM241 (Americium241) radioactive materials
Half life approximately 400 years
Local regulation to store, transport, disposal of radioactive materials -> manpower, resources
Improper handling can cause certain degree of danger to human beings and the environment
Contamination after fire occurrence

Multi-Sensors Smoke Detector - Smoke and Heat
Today’s market there are two main types:
1) Heat or smoke
Similar to install 2 detectors in same location
Each sensor has it’s own setting
2) Heat and smoke with special algorithms
Need combination of heat and smoke to activate alarm
Possible to switch off smoke detection during renovation work
