Equation 1 to Paragraph (o)(2)(i):
PSUP = PT+PLE+PSP
Where:
PSUP = Pressure required at the fire sprinkler system supply inlet. (Note: This is the pressure which is entered on the Fire Sprinkler System Certificate under "Minimum Water Supply Required.")
PT = Pressure loss in the fire sprinkler system piping.
PLE = Pressure loss from elevation change. (Note: Normally 4.4 psi for single story houses and 8.7 psi for two story houses).
PSP = Maximum pressure required by a sprinkler.

GENERAL INFORMATION
Name of Manufacturer:
Manufactured Home Serial Number:
The residential fire sprinkler system installed in this dwelling unit is in compliance with 24 CFR part 3280.214 Fire Sprinkler System Requirements. The manufactured home installer must ensure that water supply testing is completed by a fire protection technician, as required below at the home site.
Warning: When necessary, replace components only with identical components or those determined to have equivalent performance characteristics with respect to flows and pressures.
Minimum Water Supply Required
Warning: For this system to operate properly, the following minimum supply of water must be available at the point of connection to the residential fire sprinkler system (to be completed by the home manufacturer):
gpm (gallons per minute) at not less than___
psi (pounds per square inch)
The water supply shall have the capacity to provide the above required design flow rate for the sprinklers for a period of time as follows:
Where a water supply tank, a well system or a combination thereof is used, any combination of tank storage or well system shall be permitted to meet the capacity requirement.
An installer shall ensure that a fire protection technician completes and signs this Fire Sprinkler System Certificate and shall maintain a copy of the test report from the onsite testing in accordance with the home manufacturer's instructions and that the above listed required minimum water supply is available.
Company and/or Individual Name of Fire Protection Technician:

Warning: This structure contains a residential fire sprinkler system. Do not alter or make additions to the water supply without first contacting the home manufacturer or a fire protection technician. Any control valve(s) on the water supply to the residential fire sprinkler system must be in the full, open position for the system to operate properly. If the valves must be closed temporarily to service the sprinkler, verify that they are left fully open and secured when service is complete.
Warning, the water supply system supplies fire sprinklers that require specific flows and pressures to fight a fire. Devices that restrict the flow or decrease the pressure or automatically shut off the water to the fire sprinkler system, such as water filtration systems, water softeners and automatic shutoff valves, shall not be added to this system during installation without HUD approval. Later actions that may impact the water supply system should not be completed without first contacting the home manufacturer or a fire protection technician. Please do not remove this sign.
