## 3 Analysis
### Determination of ASET/RSET  
The activation time of the smoke/heat detector in the apartment of fire (AOF) origin is shown in Tables 7 and 8. Other times have been estimated or calculated analytically. ASET results are shown in Table 9. The results correspond to Trial Design 1 (all active systems are turned ON). \begin{table}
\begin{tabular}{c c} \hline
**Parameter** & **Assumption** \\ \hline \hline Egress protection system working & No fatalities (SFPE [43]) \\ \hline Sprinkler system working & No fatalities (SFPE [43]) \\ \hline RSET greater than ASET & All people in the area of analysis (apartment/retail/floor) are considered as fatalities \\ \hline Mobility impaired people & Travel speed for evacuation considered to allow for varying types of occupants \\ \hline Tenability in the stairwell & Infinite \\ \hline Scenarios with fire in the stairwell, when \\ organizational rules governing the allocation of & Not considered \\ combustible materials are fully observed & \\ \hline Fire effects outside the floor of fire origin & Not considered \\ \hline Time for the Fire brigade to secure the building & 1200 s \\ \hline High level of organization & No human and organizational error \\ \hline Middle level of organization & Human and organizational errors are associated with a probability of occurrence \\ \hline Low level of organization & All human and organizational errors occur \\  & at the same time \\ \hline Interactions between safety systems & Fire detection and sprinkler activation systems are \\  & considered as independent one from another \\ \hline Soot yield & 0.1 g/g \\ \hline CO yield & 0.026 g/g \\ \hline Upper layer temperature & \textless\textgreater{}200 \({}^{\circ}\)C \\ \hline Lower layer temperature & \textless\textless{}60 \({}^{\circ}\)C \\ \hline Visibility & \textgreater{}10 m \\ \hline FED\({}_{\text{CO}}\) & \textless{}0.3 \\ \hline FEDth & \textless{}0.3 \\ \hline \hline \end{tabular}
