## 4 Control Scenarios
### Total Flow Chart of Service
#### 4.2.2 **[Service Package #2]** Context Awareness and Actuator Control-Based Fire Detection  
Figure 9 and Table 6 show an actuator control package through detection of fire occurrence. When a fire is detected, the package blocks gas and electricity which cause fire. The following shows each step:  
1. **Fire occurrence situation:** This step blocks the damper when a fire is detected. First, the temperature sensor detects the temperature rise due to fire. Second, the gas sensor detects the gas from the fire. Third, the flame sensor detects whether a fire is caused by a fire, detects the occurrence of a fire, and cuts off the air supply through damper interception;
2. **Gas explosion situation:** This step shuts off the gas valve when detecting the occurrence of fire due to gas explosion. The gas leak detection sensors will discern whether there has been a gas leak. When a fire occurs due to a gas leak, the flame detection sensor and temperature sensor detect this. After transmitting the status information to the server, the server cuts off the gas supply through the gas valve breaker;
3. **Power overload situation:** This step cuts off electricity when detecting the occurrence of fire due to power overload. The flame detection sensor and integrated gas sensor detect and occurrence of a fire, and the electric leakage detection sensor detects a short circuit. The sensor detects whether a fire has occurred, transmits the status information to the server, and then server then cuts off the electricity supply through an electric breaker. \begin{table}
