Page
5. Sequence of Fire Sprinkler Operation:
Sprinkler head is held closed by a heat-sensitive glass bulb or link.The glass bulb or link applies
pressure to a pip cap which acts as a plug which prevents water from flowing until the ambient
temperature around the sprinkler reaches the rating of the sprinkler head(155 degrees). The
bulb/link breaks as a result of the thermal expansion.Upon activation of a sprinkler head,water
flows through the system,activating the alarm switch which is wired to an alarm panel.Water
continues to flow until a control valve is closed.
6. Testing Criteria:
The sprinkler contractor shall be responsible for arranging all testing of the system,including
notifying the building officials,fire department and engineer.
The testing criteria for the fmal acceptance shall be as defined by NFPA 13 section 25.2.1.4
