AUTOMATIC SPRINKLER PROTECTION General Automatic Sprinkler Protection System Guidelines
1. All sprinklers, valves, devices, and fittings should be FM Approved. 2. A 10 psi safety factor should be included in sprinkler system hydraulic calculations to accommodate for any future deterioration or fluctuations in the public water system. 3. All sprinkler heads should be installed using the appropriate wrench as specified by the sprinkler manufacturer. This will help to insure that the heads are installed properly without damage. 4. All sprinkler piping should be hydrostatically tested at 200 psi and should maintain that pressure without loss for 2 hours. Pressure loss should be determined by drop in gauge pressure or visual leakage. 5. The FM Global Red Tag Permit System should be utilized to supervise any valve closures during this installation. 6. Recommended sprinkler system design criteria for typical areas that will be encountered are listed in Table 1 of the Appendix. Guidance on sprinkler temperature ratings is provided in Table 2 of the Appendix. For any occupancy that does not exactly match that in the table or for guidance on determining what design to use from the table, contact the FM Global Plan Review Department or your FM Global servicing engineer. The densities in the table are presented only as guidelines; other factors may affect the recommended design criteria. 7. Final acceptance will be upon completion of the Contractor’s Material and Test Certificate (Form 85A) and field examination by an FM Global representative.
Automatic Sprinkler Protection Submittals
Automatic sprinkler protection plan submittals should consist of the following items: 1. Fire Protection Drawings of the proposed system(s). At minimum, submitted fire protection drawings should include: a. Piping layout and sizes b. Location and number of sprinklers (with sprinkler identification numbers (SIN) clearly indicated on the drawing). c. Location of remote area used in hydraulic calculations 2. Hydraulic Calculations 3. Specifications for materials being used, including but not limited to:
