What is the primary function of an alarm valve in a sprinkler system?

The primary function of an alarm valve in a sprinkler system is to signal an alarm when a sprinkler head is activated. When the system detects heat and a sprinkler head opens, water flows through the system, which triggers the alarm valve to activate an alert. This is crucial for notifying occupants and emergency responders about the fire, enabling a timely and effective response.

Understanding this role is essential for grasping how sprinkler systems work in fire protection and alert systems. The alarm valve ensures that any activation of the sprinkler system not only suppresses the fire but also communicates the event to necessary parties, enhancing overall safety.
