Part number shown is the base part number. For complete part number, contact Viking.
3.
For areas of coverage smaller than shown, use the "Flow" and "Pressure" for the next larger area listed. Flows and pressures listed are per sprinkler. The distance from
4.
sprinklers to walls shall not exceed one-half the sprinkler spacing indicated for the minimum "Flow" and "Pressure" used. For detailed guidance on obstructions please
refer to the relevant EN16925, NFPA13, 13R or 13D design and installation standards. The minimum flow for each sprinkler shall be selected such that both the actual
width and length dimensions are equal to or less than those given in the table above.
Minimum LPCB approved flow and pressure for each room size.
5.
Flow and pressure required to achieve nominal density, or minimum approved flow and pressure if higher.
6.
The nominal density is that used for design purposes and required by the installation standard. As a proportion of the flow is required to wet the walls the actual density
7.
on the floor will be lower than nominal. Product testing and approvals are carried out at the minimum values given above and so design should be based on the values
given above and does not need to be adjusted to take account of wall-wetting.
