What is the required action when an automatic sprinkler system activates?

When an automatic sprinkler system activates, the required action is to notify the fire department. This is essential because the activation of a sprinkler system usually indicates that a fire has been detected, and the sprinklers are responding to combat the flames. Even though the sprinklers may significantly reduce the risk of fire spreading and can control or extinguish the fire, emergency services must be informed to take over the situation, ensure safety, and conduct any necessary rescue operations.

This action aligns with fire safety protocols, which emphasize that immediate notification of emergency services is crucial in the event of a system activation. Emergency personnel can provide professional assistance, assess the situation thoroughly, and respond effectively to any potential hazards that may arise during a fire incident.

While other actions such as manual verification or evacuation might be important in certain contexts, they do not replace the critical need for professional intervention in a fire emergency. Therefore, notifying the fire department is the most appropriate and necessary response in this situation.
