Answer :
Final answer:
The most appropriate battery configuration for the 24 V fire alarm system would be a single 24 V battery.
Explanation:
To determine the most appropriate battery configuration for the 24 V fire alarm system, we need to consider the quiescent load and the load in alarm. When in quiescent state (not in alarm), the system has a load of 0.5 A. When in alarm, the load increases to 4.0 A.
For the system to work properly, the battery configuration should provide enough voltage to power both the quiescent load and the load in alarm. Based on this requirement, the most appropriate battery configuration would be a single 24 V battery. Since a single 24 V battery can provide the necessary voltage, there is no need for multiple batteries or configurations.
Therefore, the correct answer is option b) Single 24 V battery.
