Retractable telescoping fire sprinkler |
摘要 |
A retracting telescoping automatic fire sprinkler is disclosed. In a dry system, the sprinkler extends to its operating position under system pressure that is applied in response to a preaction signal. When system pressure is removed, as in after a test is completed, the sprinkler automatically retracts to its original position.
