| 2017-09-08 10:52:40 | 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) TEST AT WORKING PRESSURE FOR 2 HOURS PER NFPA 13. |
| | |
| | 2) USE FIRE PUMP TEST PRESSURE FOR WORKING PRESSURE |
| | CALCULATIONS. |
| | |
| | 3.3.19 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. |
| | |
| | 24.2.1.2 PORTIONS OF SYSTEMS NORMALLY SUBJECTED TO |
| | SYSTEM WORKING PRESSURES IN EXCESS OF 150 PSI (10.4 |
| | BAR) SHALL BE TESTED AS DESCRIBED IN 24.2.1.1, AT A |
| | PRESSURE OF 50 PSI (3.5 BAR) IN EXCESS OF SYSTEM |
| | WORKING PRESSURE. |
| | 24.2.1.4 MODIFICATIONS AFFECTING 20 OR FEWER SPRINKLERS |
| | SHALL NOT REQUIRE TESTING IN EXCESS OF SYSTEM WORKING |
| | PRESSURE. |
| | 24.2.1.5 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. |
| | 24.2.1.6 MODIFICATIONS THAT CANNOT BE ISOLATED, SUCH AS |
| | RELOCATED DROPS, SHALL NOT REQUIRE TESTING IN EXCESS OF |
| | SYSTEM WORKING PRESSURE. |
| | 24.2.1.7 LOSS SHALL BE DETERMINED BY A DROP IN GAUGE |
| | PRESSURE OR VISUAL LEAKAGE. |
| | 24.2.1.8* 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. |
