| | REVIEW COMMENTS - FIRE DEPARTMENT |
| | |
| | THE PLANS DO NOT REFERENCE CONFORMANCE WITH NFPA 14. |
| | |
| | THE PLANS ONLY INDICATE CONFORMANCE WITH NFPA 13; |
| | HOWEVER, THE HYDRAULIC CALCULATIONS AND DESIGN INDICATE |
| | A DESIGN DENSITY OF 0.05 FOR 4 SPRINKLERS WHICH IS |
| | ASSOCIATED WITH NFPA 13R. |
| | |
| | IN ORDER TO USE QUICK-RESPONSE SPRINKLERS IN LIEU OF |
| | RESIDENTIAL SPRINKLERS WITHIN THE DWELLING UNIT, THE |
| | WHOLE DWELLING UNIT NEEDS TO BE PROTECTED WITH FOUR OR |
| | FEWER SPRINKLERS, SO THE ROOM DESIGN METHOD MIGHT BE |
| | MORE EFFICIENT. PER NFPA 13R SECTION 6.2.1.3, LISTED |
| | QUICK-RESPONSE SPRINKLERS SHALL BE PERMITTED TO BE |
| | INSTALLED IN DWELLING UNITS MEETING THE DEFINITION OF A |
| | COMPARTMENT, AS DEFINED IN SECTION 3.3, WHERE NO MORE |
| | THAN FOUR SPRINKLERS ARE LOCATED IN THE DWELLING UNIT. |
| | NFPA 13R REQUIRES THE ENTIRE DWELLING UNIT TO BE SMALL |
| | ENOUGH TO BE PROTECTED WITH FOUR SPRINKLERS IN ORDER TO |
| | APPLY 6.2.1.3. THIS REQUIREMENT DOES NOT MEAN THAT EACH |
| | COMPARTMENT NEEDS ONLY FOUR SPRINKLERS, IIT MEANS THAT |
| | THE WHOLE DWELLING UNIT, INCLUDING ALL OF THE SLEEPING |
| | ROOMS, CLOSETS, BATHROOMS, FOYERS, AND NOOKS, HAS TO BE |
| | SMALL ENOUGH TO BE PROTECTED WITH FOUR OR FEWER |
| | SPRINKLERS. IF QUICK-RESPONSE SPRINKLERS ARE USED IN |
| | ACCORDANCE WITH 6.2.1.3, THE SYSTEM MUST BE ABLE TO |
| | PROVIDE A MINIMUM DENSITY OF 0.1 GPM/FT2 (4.1 MM/MIN) |
| | OVER THE DESIGN AREA, WHICH IS THE ENTIRE DWELLING UNIT |
| | IN THIS CASE (USING THE ?ROOM DESIGN METHOD? FROM NFPA |
| | 13, 11.2.3.3). QUICK-RESPONSE SPRINKLERS ARE CURRENTLY |
| | NOT EVALUATED FOR PERFORMANCE AT LOWER DENSITIES SUCH |
| | AS 0.05 GPM/FT2 (2.04 MM/MIN). THE MINIMUM DENSITY |
| | REQUIREMENT HAS ALSO BEEN ADDED TO 6.2.1.4, SINCE |
| | QUICK-RESPONSE SPRINKLERS ARE PERMITTED BY THAT |
| | PARAGRAPH AS WELL. THE MINIMUM DENSITY OF 0.10 GPM/FT2 |
| | (4.1 MM/MIN) IS CONSISTENT WITH THE REQUIREMENTS FOR |
| | THE USE OF QUICK-RESPONSE SPRINKLERS IN NFPA 13. |
| | |
| | NOTE: CHANGING THE QUICK RESPONSE SIDEWALL SPRINKLERS |
| | TO RESIDENTIAL SIDEWALL SPRINKLERS WILL RESULT IN THE |
| | MAJORITY OF THE SIDEWALL SPRINKLERS BEING OBSTRUCTED BY |
| | THE ADJACENT SOFFITS DUE TO THE SPRINKLER LOCATION |
| | DIFFERENCES AND OBSTRUCTION RULE DIFFERENCES. |
| | |
| | PROVIDE LOCKING KNOX CAPS ON FIRE DEPARTMENT |
| | CONNECTION. |
| | |
| | NOTE: A SEPARATE UNDERGROUND FIRELINE (UG FIRELINE) |
| | PERMIT IS NEEDED FOR THE INSTALLING CONTRACTOR. |
