| 2019-08-05 10:56:26 | 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 TEST AT 200PSI FOR |
| | 2HRS. |
| | |
| | IF NOT: |
| | |
| | 2) TEST AT WORKING PRESSURE FOR 2 HOURS PER NFPA 13. |
| | |
| | 3) USE FIRE PUMP TEST PRESSURE FOR WORKING PRESSURE |
| | CALCULATIONS. |
| | |
| | PER NFPA 13 |
| | |
| | 3.3.23 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 25.2.1.8, |
| | 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 (10.4 |
| | BAR) SHALL BE TESTED AS DESCRIBED IN 25.2.1.1, AT A |
| | PRESSURE OF 50 PSI (3.5 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 AFFECTING 20 OR FEWER SPRINKLERS |
| | SHALL NOT REQUIRE TESTING IN EXCESS OF SYSTEM WORKING |
| | PRESSURE. |
| | 25.2.1.5 WHERE ADDITION OR 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. |
| | 25.2.1.6 MODIFICATIONS THAT CANNOT BE ISOLATED, SUCH AS |
| | RELOCATED DROPS, SHALL NOT REQUIRE TESTING IN EXCESS OF |
| | SYSTEM WORKING PRESSURE. |
| | 25.2.1.7 LOSS SHALL BE DETERMINED BY A DROP IN GAUGE |
| | PRESSURE OR VISUAL LEAKAGE. |
| | 25.2.1.8* 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. |
