What action is taken when the water level in the tank falls too low?

When the water level in the tank falls too low, pump activation is initiated to address the drop in water levels. This action is crucial for maintaining the operational efficiency of the sprinkler system. The pumps are designed to automatically start when the water level is detected to be below a designated threshold, ensuring that the system can refill the tank. This mechanism prevents potential issues related to insufficient water supply, which could compromise the effectiveness of the fire protection system. By activating the pumps, the system can restore the water level back to acceptable limits, thereby maintaining readiness for any fire suppression needs.

Other actions, such as alarm activation or manual water filling, may also be part of the overall system but are secondary to the primary function of ensuring an adequate water supply through pump activation. Alarm activation typically serves as a notification mechanism rather than a corrective action, while manual water filling is not an automatic response and can introduce delays in addressing the low water level issue. Tank inspection is also not a direct response to low water levels; it would be a follow-up action to identify potential leaks or issues that might have caused the water level to drop.
