| 2022-11-07 12:16:21 | THIS PLAN WAS REVIEWED AND APPROVED BY PETER LEDUC, |
| | FIRE MARSHAL, WITH THE FOLLOWING COMMENTS: |
| | |
| | PLEASE CONSIDER THE FOLLOWING AS PROVISO: |
| | |
| | THESE PROVISO COMMENTS WILL BE VERIFIED AND CONFIRMED |
| | AT THE TIME OF FIRE INSPECTION. FAILURE TO FOLLOW THESE |
| | PROVISO COMMENTS WILL RESULT IN A FAILED FIRE |
| | INSPECTION. |
| | |
| | 1) RELOCATED DROPS MAY NOT BE ABLE TO BE ISOLATED; |
| | HOWEVER, THE FLOOR AREA MAY AND BE TESTED AT 200PSI FOR |
| | 2HRS. |
| | |
| | IF NOT OR LESS THAN 20 HEADS: |
| | |
| | 2) TEST AT WORKING PRESSURE FOR 2 HOURS PER NFPA 13. |
| | |
| | 3) USE FIRE PUMP TEST PRESSURE FOR WORKING PRESSURE |
| | CALCULATIONS MINUS 5 PSI PER FLOOR FOR ELEVATION |
| | PRESSURE LOSS. |
| | PER NFPA 13 |
| | |
| | 3.3.24 SYSTEM WORKING PRESSURE. THE MAXIMUM ANTICIPATED |
| | STATIC (NONFLOWING) OR FLOWING PRESSURE APPLIED TO |
| | SPRINKLER SYSTEM COMPONENTS EXCLUSIVE OF SURGE |
| | PRESSURES AND EXCLUSIVE OF PRESSURE FROM THE FIRE |
| | DEPARTMENT CONNECTION. |
| | |
| | 25.2 ACCEPTANCE REQUIREMENTS. |
| | |
| | 25.2.1* HYDROSTATIC TESTS. |
| | 25.2.1.1 UNLESS PERMITTED BY 25.2.1.2 THROUGH 25.2.1.5, |
| | ALL PIPING AND ATTACHED APPURTENANCES SUBJECTED TO |
| | SYSTEM WORKING PRESSURE SHALL BE HYDROSTATICALLY TESTED |
| | AT 200 PSI (13.8 BAR) AND SHALL MAINTAIN THAT PRESSURE |
| | WITHOUT LOSS FOR 2 HOURS. |
| | 25.2.1.2 PORTIONS OF SYSTEMS NORMALLY SUBJECTED TO |
| | SYSTEM WORKING PRESSURES IN EXCESS OF 150 PSI (10.3 |
| | BAR) SHALL BE TESTED AS DESCRIBED IN 25.2.1.1, AT A |
| | PRESSURE OF 50 PSI (3.4 BAR) IN EXCESS OF SYSTEM |
| | WORKING PRESSURE. |
| | 25.2.1.3 WHERE COLD WEATHER WILL NOT PERMIT TESTING |
| | WITH WATER, AN INTERIM AIR TEST SHALL BE PERMITTED TO |
| | BE CONDUCTED AS DESCRIBED IN 25.2.2. THIS PROVISION |
| | SHALL NOT REMOVE OR REPLACE THE REQUIREMENT FOR |
| | CONDUCTING THE HYDROSTATIC TEST AS DESCRIBED IN |
| | 25.2.1.1. |
| | 25.2.1.4 MODIFICATIONS TO EXISTING PIPING SYSTEMS SHALL |
| | REQUIRE TESTING AT SYSTEM WORKING PRESSURE. |
| | 25.2.1.4.1 WHERE MODIFICATION IS MADE TO AN EXISTING |
| | SYSTEM AFFECTING MORE THAN 20 SPRINKLERS, THE NEW |
| | PORTION SHALL BE ISOLATED AND TESTED AT NOT LESS THAN |
| | 200 PSI (13.8 BAR) FOR 2 HOURS. |
| | 25.2.1.4.2 MODIFICATIONS THAT CANNOT BE ISOLATED, SUCH |
| | AS RELOCATED DROPS, SHALL REQUIRE TESTING AT SYSTEM |
| | WORKING PRESSURE. |
| | 25.2.1.5* THE TEST PRESSURE SHALL BE READ FROM A GAUGE |
| | LOCATED AT THE LOW ELEVATION POINT OF THE SYSTEM OR |
| | PORTION BEING TESTED. THE PRESSURES IN PIPING AT HIGHER |
| | ELEVATIONS SHALL BE PERMITTED TO BE LESS THAN 200 PSI |
| | (13.8 BAR) WHEN ACCOUNTING FOR ELEVATION LOSSES. |
| | SYSTEMS OR PORTIONS OF SYSTEMS THAT CAN BE ISOLATED |
| | SHALL BE PERMITTED TO BE TESTED SEPARATELY. |
| | |
| | 25.2.1.8* WHEN SYSTEMS ARE BEING HYDROSTATICALLY |
| | TESTED, TESTS SHALL BE PERMITTED TO BE CONDUCTED WITH |
| | PENDENT OR HORIZONTAL SIDEWALL SPRINKLERS OR PLUGS |
| | INSTALLED IN FITTINGS. ANY PLUGS SHALL BE REPLACED WITH |
| | PENDENT OR HORIZONTAL SIDEWALL SPRINKLERS AFTER THE |
| | TEST IS COMPLETED. |
| | |
| | 25.2.1.10 PROVISION SHALL BE MADE FOR THE PROPER |
| | DISPOSAL OF WATER USED FOR FLUSHING OR TESTING |
| | |
| | 4) PLEASE ENSURE THAT A MECHANICAL INSPECTION # 603 - |
| | FIRE SPRINKLER PIPE IS CALLED IN WITH FIRE SPRINKLER |
| | #310 ??? FIRE SPRINKLER HEAD AND # 311 - PRESSURE TEST |
| | INSPECTIONS. |
| | |
| | 5) CONTRACTOR TO PROVIDE FOR WORKING PRESSURE |
| | VERIFICATION (I.E. PRESSURE GAUGE 2HRS) AND/OR SYSTEM |
| | IS CHARGED/DISCHARGED UNDER WORKING PRESSURE. (I.E. |
| | VISUAL FOR LEAKS & INSPECTOR DRAIN AFTER 2 HRS) |
