Fire System
Pollution Control Units often require a fire system to be installed with the PCU. CORE or Ansul R-102
Fire Suppression Systems are available for the PCU. PCU fire systems use fusible links or electric
sensors set at 360°F to activate the fire system. Outdoor Ansul R-102 installations require a climate
controlled cabinet to ensure the fire system does not drop below 32°F and does not exceed 130°F. See
below for more information about outdoor installations. The Pollution Control Unit fire system must be
interlocked with a hood fire system so that if the hood system activates, the PCU system activates.
Reverse activation is required by code, and is recommended for safety. Details of this interlock can be
found in the installation guide provided by the fire system manufacturer.
In the event that the fire system is accidentally activated, all disposable filters must be replaced and the
prefilter cleaned. The water or chemical agent used in the fire system can cause the filters to prematurely
fail.
In the event that a fire occurs in the ductwork leading to the PCU or inside the PCU, the following must be
completed. The unit must be cleaned of all fire suppression chemicals and grease. The filters must be
replaced, this includes the prefilter. If any of the gasketing is damaged, replace the gasketing between
modules and between the doors. If any of the components that make-up the Pollution Control Unit are
damaged by fire, then that component must be replaced and inspected by factory trained service
personnel.
Installation, commissioning, or resetting of the fire system must be done by a
licensed fire system installer, per the guidelines set forth by the fire system
manufacturer.
Climate Controlled Utility Cabinet
For outdoor installations, a climate controlled cabinet is available to house the fire system. This box
contains a heater, an exhaust fan, and thermostats to control the temperature inside the cabinet. The
Utility Cabinet thermostats come preset to heat below 40° F and cool above 90° F. The climate controlled
cabinet requires a dedicated 15 amp, 60 Hz, 115 volt, single phase electrical service.
