Answer :
Final answer:
The primary devices that supervise automatic sprinkler systems are Supervisory devices, which monitor the system's operational status. Waterflow devices are also essential as they detect the flow of water, indicating system activation during a fire. Flame and fire-gas detectors, while important for fire detection, do not supervise sprinkler systems directly.
Explanation:
Devices Supervising Automatic Sprinkler Systems
The primary automatic alarm-initiating devices that supervise automatic sprinkler systems and monitor their conditions are called Supervisory devices. These devices are designed to ensure that the sprinkler system is in proper working condition and to signal any issues that may arise, such as a loss of water pressure, valve tampering, or even a malfunctioning pump.
In addition to supervisory devices, Waterflow devices play a critical role. They detect the flow of water within the sprinkler system to confirm that the system is active and can trigger alarms when water is flowing during an event, indicating that a fire incident may be occurring. This ensures prompt response actions are taken by the firefighting teams.
While Flame detectors and Fire-gas detectors are crucial for identifying the presence of fire or hazardous gases in an environment, they do not specifically monitor the condition of the sprinkler systems as supervisory and waterflow devices do.
