NOTE: Firetrace Pre-Engineered ILP Automatic Suppression Units are designed and approved as an automatic unit. Firetrace ILP Units are not designed
to provide simultaneous actuation of two or more units. Under the approval, only one Firetrace Pre-Engineered ILP Automatic Suppression Unit can be
used to protect one enclosure, units shall not be combined to protect a larger enclosure.
Table 20 - Enclosure Size and Nozzle Limitations
4.5 Required Amounts of Agent
4.5.1 Minimum Design Concentrations
The minimum design concentrations to be used with Firetrace FK-5-1-12 units include a minimum safety factor (SF), as specified in NFPA 2001.
Consult the Firetrace website, or contact Firetrace if the hazard you desire to protect is not listed.
For Class B hazards, refer to Annex B of NFPA 2001 for the cup burner extinguishment concentration value for the particular Class B fuel(s) to be
protected. Choose the fuel with the highest cup burner extinguishment value in the hazard and apply a 30% safety factor (multiply this extinguishment
concentration value by 1.3) for the design concentration. The minimum design concentration for the protection of all Class B hazards shall be as per
Table 22 – Class B Minimum Design Concentrations. Contact Firetrace for guidance on hazards deviating from these requirements or for fuels not
listed.

CAUTION
This unit is designed and Listed as an Automatic unit. No Manual or electric means is provided for simultaneous
actuation of multiple units. Only one (1) unit can be used to protect one hazard. These extinguisher units cannot
be combined to protect a larger size hazard since they are not designed to provide for simultaneous actuation of
two (2) or more units.
