FIRE SUPPRESSION SYSTEM
The MM1 hood may be ordered pre-piped with a fire suppression system. Local codes or a desire
for enhanced fire safety may dictate the inclusion of fire protection in the hood. The hood, if ordered
pre-piped, will come with the detector bracket and fire protection nozzles installed in the exhaust
plenum of both hood pods to cover the requirements of the duct protection and exhaust plenum
protection. The local Ansul fire system installer must supply the distribution piping, Ansul Automan
and suppressant tanks, detector conduit and wire rope runs, fusible links, remote pull station,
Ansulex liquid fire suppressant and all other supplies to complete the fire system installation. If
appliance protection is required the local Ansul installer must also design and install the distribution
piping and nozzles for this requirement. This work must be performed by the Ansul system installer.
The side skirts on the rear of the hood require notches to be cut or holes to be punched to allow
access for the appliance protection distribution piping. Notches would be used if the side skirts
are to be removed for cleaning later. The illustrations below depict the typical layout for an MM1
hood fire system. The pre-pipe components supplied by Halton are shown in solid lines and the
components supplied by others are shown in dashed lines. The complete fire system must satisfy
the requirements of the National Fire Protection Association (NFPA), Underwriters Laboratories
Standard 300 and all local codes and Authorities Having Jurisdiction.
Please note: Maintain all clearances necessary for access, maintenance and cleaning when the oven
is positioned for final assembly and installation of the fire suppression system.
