UL Listed concealed pendant automatic glass bulb fire sprinklers featuring a 5.6 K-factor with flat plate concealed design for discreet ceiling installations.

Suitable for standard coverage applications in commercial and residential settings.
Product Overview
The Series FA019 and FA020 fire sprinklers are designed for discreet ceiling installations and are activated when exposed to heat from a fire. The sprinkler’s soldered cover plate detaches at its rated temperature, exposing the glass bulb to heat. As the bulb heats, internal fluid expands and compresses the air bubble within. Once maximum compression is reached, the pressure breaks the glass bulb, triggering water discharge to suppress the fire.
