Caution
The above typical spray patterns have been generated with a sprinkler properly installed
below a smooth, level, unvented ceiling. Minor water spray may exceed the pattern
shown. Any deviation to the piping arrangement, deflector distance below the ceiling,
water pressure, obstructions on the ceiling, ventilation, etc., may affect the spray pattern.
Sprinklers are designed and approved to meet specific spray patterns and other criteria
established by the testing agencies. The testing criteria and method has been
established to meet specific installation rules. Deviation from recognized installation
rules must be approved by the Authority Having Jurisdiction. Only full scale fire testing
can establish if reasonable fire protection is being provided when recognized installation
rules are not followed.
