2.6 Discharge Nozzles
(See Figure 2.6)
Discharge nozzles are used to disperse the FM-200® agent. Available in brass or stainless steel, the nozzles
are performance tested to ensure that the agent is properly distributed throughout the protected area (Brass
nozzles are UL Listed and FM Approved. Stainless steel nozzles are UL Listed; FM Approval pending).
Discharge nozzles are available with three separate port arrangements to accommodate placement in varying
locations around a room or enclosure: 90° (1 port) corner nozzles, 180° (2 port) sidewall nozzles, and 360° (4
port) radial nozzles. Each nozzle is stamped with the nozzle part number and orice diameter.
