GENERAL TEST PROCEDURES
Smoke Management Systems: (continued) (f) Pressurized Stair-Shaft System: Inspect the system for proper status prior to activating system. Activate any fire alarm initiating device to automatically activate the system. Inspect the status panel in the building fire control room/station for proper operation. (g) Airflow Requirement: Determine that the system has the minimum airflow requirement. Measure a typical cross-sectional area in the stair-shaft in square feet and multiply by 50 linear feet per minute. With all doors closed using an approved anemometer at the exhaust point, determine that the system meets 90 percent of the minimum required CFM while maintaining a positive pressure. (h) Door Opening Force: Door opening force is obtained by using an approved door testing device applied in a direct vertical line above the axis of the door knob/lever. [1] Test 1: With the system on and all doors closed, the maximum allowable pressure that is required to open that door should be 30 lbs. That door must close and latch when released. [2] Test 2: With the system on one door open plus one additional door open, the maximum allowable pressure to open the door shall be 15 lbs. Door must close and latch when released. [3] Test 3: In tests 1 and 2, stair-shaft doors that swing outward must close and latch after being opened and released. [4] Test 4: System fans off, exit doors that swing outward (i.e. exit to the roof and a public way) require a door opening force of not more than 30 lbs. [5] Test 5: With the system off all doors in stair-shaft must close and latch after being opened and released. See F-340R Pressurized Stair Shaft Fire Protection Equipment Performance Report for additional procedures M. Sprinkler Systems, Automatic: Wet, Dry, Pre-action, Deluge & Foam Determine that all equipment is in proper operating condition and well maintained in accordance with applicable portions of NFPA-13 and Title 19/NFPA 25California Edition NOTE: 11/2 “ Hose stations connected to automatic sprinkler systems installed under NFPA 13 are not required to meet flow requirements of NFPA 14 or Title 19/NFPA 25 California Edition.

Fire Department Connection: Determine that appropriate inlet connections are provided and are in operable condition. Determine that approved signs have been provided. Incorrect or missing signs shall be noted by the Certified Tester in section V of the F-340R Automatic Fire Sprinkler 5 year Fire Protection Equipment Performance Report for Fire Department follow-up inspection.
