Product Overview
The LIFEGUARD Sprinkler Upright UL is specifically designed for installations where sprinkler piping is exposed below the ceiling. Mounted in the upright position, the sprinkler remains sealed by a liquid-filled glass bulb under normal conditions.
When the ambient temperature reaches the sprinkler's rated activation point during a fire, the glass bulb breaks, allowing water to flow through the sprinkler body. The upward-facing deflector disperses water into a carefully engineered spray pattern, providing effective coverage over the protected area and helping contain or extinguish the fire before it spreads.
Its UL Listing demonstrates compliance with globally recognized testing standards for reliability, durability, and operational performance, making it a trusted choice for professional fire protection systems.

How the Sprinkler Works
The sprinkler remains sealed during normal operating conditions by a specially designed glass bulb.
In the event of a fire:
Rising temperatures heat the glass bulb.
The liquid inside the bulb expands.
The bulb breaks at its rated activation temperature.
Water flows through the sprinkler body.
The precision deflector distributes water evenly across the protected area.
The fire is suppressed or controlled, helping prevent further spread.
Only sprinklers directly exposed to sufficient heat activate, reducing unnecessary water discharge and minimizing damage to unaffected areas.
