A 200°F Pendent Bulb, Brass is a key component used in automatic fire sprinkler systems, designed to activate when temperatures reach a specific level. Rated at 200°F, it responds to higher heat conditions, making it suitable for areas where elevated temperatures are expected.

The pendent design allows it to hang downward from the sprinkler head, ensuring effective water distribution when activated. The glass bulb contains a heat-sensitive liquid that expands and breaks at the set temperature, triggering the release of water.
