• Operation: It is a self-activating fire suppression device. It does not require manual intervention to start.
• Mechanism: The top is fitted with a heat-sensitive glass bulb sprinkler head. When an area reaches a specific temperature threshold (typically 68°C), the fluid inside the glass bulb expands and breaks it, automatically releasing the pressurized dry chemical powder underneath to suppress the fire.
• Common Placement: These units are typically suspended or mounted on ceilings directly above high-risk or unstaffed areas like server rooms, fuel storage areas, engine compartments, and electrical switchrooms.
