What happens if the water level in a pressurized sprinkler tank falls below the required level?

When the water level in a pressurized sprinkler tank falls below the required level, it is critical to send a signal to the monitoring system. This signal indicates that the water supply is insufficient to operate the sprinkler system effectively, which is vital for fire protection. By sending a signal, appropriate action can be taken to address the low water level, such as refilling the tank or investigating possible issues that led to the drop in level. This proactive approach ensures that the fire protection system remains operational and ready to respond in case of an emergency.

While other actions may also follow in response to the low water level, the immediate and necessary step is to relay that information through a signal to ensure safety measures can be maintained.
