Product Description

The F1S5 Series Glass Bulb Sprinkler combines the 

durability of a standard sprinkler with the attractive low profile 
of a decorative sprinkler. Whether installed on exposed piping 
or in an office ceiling, it is functional and attractive. 

Beautifully versatile is the description for the Reliable Model 

F1S5 Series Recessed glass bulb sprinkler. Recessing the 
F1S5 Series enhances its already low profile decorative 
appearance and facilitates a rapid and perfect installation.

Model F1S5 Series Recessed escutcheon is highly 

adjustable. The two piece construction makes field 
installation a very easy and rapid task. This also allows ceiling 
panels to later be removed without shutting down the fire 
protection system, thus facilitating maintenance of above 
ceiling services.
