| | CONNECTION. |
| | |
| | THE EXTENDED COVERAGE SPRINKLER LOCATED IN THE SECOND |
| | FLOOR CEILING IS PROTECTING THE FIRST FLOOR'S FLOR AREA |
| | AND SHOULD BE PIPED SO A WATER FLOW ALARM IS ACHIEVED |
| | ON THE FIRST FLOOR AND NOT THE SECOND FLOOR SO ARRIVING |
| | FIREFIGHTERS DO NOT ASSUME THE FIRE IS ON THE SECOND |
| | FLOOR. |
| | |
| | NO HYDRAULIC CALCULATIONS SUBMITTED SUPPORTING THE |
| | WATER CURTAIN DEMAND FOR THE FIRST FLOOR OPENING. UPPER |
| | CEILING HEIGHT MAY EXCEED THE 20 FOOT THRESHOLD FOR THE |
| | AREA REDUCTION METHOD FOR QUICK RESPONSE SPRINKLERS. |
| | PER NFPA 13 SECTION 11.3.3.3 IF A SINGLE FIRE CAN BE |
| | EXPECTED TO OPERATE SPRINKLERS WITHIN THE WATER CURTAIN |
| | AND WITHIN THE DESIGN AREA OF A HYDRAULICALLY |
| | CALCULATED SYSTEM, THE WATER SUPPLY TO THE WATER |
| | CURTAIN SHALL BE ADDED TO THE WATER DEMAND OF THE |
| | HYDRAULIC CALCULATIONS AND SHALL BE BALANCED TO THE |
| | CALCULATED AREA DEMAND. HYDRAULIC DESIGN CALCULATIONS |
| | SHALL INCLUDE A DESIGN AREA SELECTED TO INCLUDE CEILING |
| | SPRINKLERS ADJACENT TO THE WATER CURTAIN. |
| | |
| | THE MAIN CORRIDOR ON THE SECOND FLOOR IS PROTECTED BY |
| | EXTENDED COVERAGE SPRINKLERS; HOWEVER, THERE ARE LOWER |
| | SOFFITS IN THIS CORRIDOR THAT DO NOT APPEAR TO BE |
| | PROPERLY PROTECTED DUE TO SPRAY OBSTRUCTIONS CAUSED BY |
| | CEILING/SOFFIT HEIGHT DIFFERENCES. |
| | |
| | THE HYDRAULIC CALCULATION HAS THE LONG SIDE (1.2 X THE |
| | SQUARE ROOT OF THE AREA OF SPRINKLER OPERATION) OF THE |
| | HYDRAULIC AREA DRAWN PERPENDICULAR TO THE BRANCH LINES |
| | WHEN THE LONG SIDE OF THE HYDRAULIC AREA SHOULD BE RUN |
| | PARALLEL TO THE BRANCH LINES PER NFPA 13 (2010 EDITION) |
| | SECTION 22.4.4.1.1.1. |
| | |
| | PROVIDE A HYDRAULIC CALCULATION FOR THE SOUTHEAST AREA |
| | OF THE SECOND FLOOR (EDUCATIONAL ROOMS) WHERE THE |
