The Amerex “Zone Defense” System provides two types of appliance protection; “Zone of Protection” and “Dedicated Appliance Protection.” The following is a list of eligible cooking appliances and their maximum cooking hazard size that may be protected with the “zone of protection” nozzle coverage.

ZONE DEFENSE
Note: Maximum & minimum heights must be measured vertically from the tip of nozzle to the top of the appliance.
14178 Nozzles – 2 F-Point used.
Nozzles are a maximum of 500mm apart on center and max 150mm from each end of the hood.
All nozzles are in a straight line, 1150 – 1275mm above the surface of the appliances, aimed straight down.
The protected rectangular area is 850mm (425mm from centerline of the nozzles) x length of the hood.

ZD LIMITATIONS
The ZD nozzles cannot protect cooking appliances with an enclosed cooking area such as an upright broiler or salamander.
Enclosed appliances must be covered by the standard KP appliance specific protections outlined in section 3 of this manual.
No ZD nozzles are required above the appliance protected by a dedicated nozzle.
The location of appliance specific protection is fixed and the appliance must remain in this location.
