When a fire detection system is electrically supervised, what does it indicate about the power supply?

1. It will shut down upon overload

2. It will signal a fault during a single outage

3. It requires manual operation

4. It is immune to interruptions

The correct answer is: It will signal a fault during a single outage

When a fire detection system is electrically supervised, it typically means that the system continuously monitors the integrity of its power supply and connections. The correct answer indicates that the system will signal a fault if there is a failure of the power supply during even a single outage. This feature is crucial in safety systems because it ensures that any interruption in power can be promptly detected, allowing for immediate action to ensure safety. In electrically supervised systems, the monitoring capability helps to maintain a high level of reliability and ensures that potential issues can be identified before they lead to complete system failure. This is particularly important in fire detection, where constant functionality is essential for early warning and prevention. The other answer choices do not accurately describe the role of electrical supervision. For example, the notion that the system would shut down upon overload is misleading as the focus is on continuous monitoring of performance rather than simply shutting down. Similarly, manual operation is contrary to the automated nature of most fire detection systems, while the idea that the system is immune to interruptions overlooks the very reason for having electrical supervision—to identify and alert for faults or interruptions.
