3. PRODUCT DESCRIPTION
Viking Micromatic
®
Special Response
Sprinklers are small thermosensitive
glass bulb sprinklers available in various
finishes, temperature ratings, and orifice
sizes to meet design requirements.
During fire conditions, the heat-sensitive
liquid in the glass bulb expands, causing
the bulb to shatter, releasing the pip cap
and sealing spring assembly. Water
flowing through the sprinkler orifice
strikes the sprinkler deflector forming a
uniform spray pattern to extinguish or
control the fire.
