e. Exercising the power disconnect for each individual fan confirmed the fan stops running and a FAULT and OFF condition illuminated at the Fire-fighter's Smoke Control Panel. f. Failure of the smoke control fan's damper to fully open or fully close created a FAULT condition on the Fire-fighter's Smoke Control Panel. g. Exercising the power disconnect for the damper confirmed the damper fails to the OPEN position and a FAULT and OPEN condition illuminated at the Fire-fighter's Smoke Control Panel. 2. Labeling has been provided for the smoke control fans and their associated maintenance disconnects, smoke control dampers, and VFD's. 3. Upon fire alarm activation within the building (smoke detectors, waterflow switches, manual pull stations), the stairway pressurization systems automatically activated- pressurization dampers opened, and the fans energized. 4. Upon fire alarm activation within the building (smoke detectors, waterflow switches, manual pull stations), the opening protectives (HVAC combination fire/smoke dampers) closed, and the elevator lobby doors closed. 5. Upon activation of the pressurization fan duct -detector under an automatic pressurization condition, the smoke control fan was de -energized while illuminating correct LEDs on the Fire- fighter's Smoke Control Panel. Manual re -activation of the fan was achieved at the FSCP panel via the fan control toggle switch. 6. Various initiating devices on each level were activated, resulting in correct posturing and status indication of the stair pressurization systems. Individual fire alarm initiating devices which activate any portion of the smoke control system were verified to provide applicable output functions. A review of the fire alarm control unit programming indicated general alarm initiating devices (smoke detectors, heat detectors, waterflow detectors, and manual pull station) were correctly programmed to result in a general building alarm condition and initiate automatic pressurization sequences. 7. Performance testing of each stairway pressurization system was satisfactorily conducted. All tests were observed and recorded with all stairway pressurization systems operating simultaneously under an automatic fire alarm condition. Specific testing of the stairway pressurization systems was completed per the International Building Code (IBC) Section 909 including the following: a. With all stair doors closed, pressure differences across each pressurized stairway door of each level were measured using nationally recognized methods. b. The measured pressure differentials were observed to be sufficient to provide a minimum of 0.10 inches of water column and a maximum of 0.35 inches of water column in the shaft relative to the corridor of the building, measured with all stairway doors closed. c. Door opening force measurements were taken at all pressurized egress doors and were found to be less than 30 pounds of force to set the door in motion, and less than 15 pounds of force to completely open with the smoke control systems operating. 8. Full testing of the Fire-fighter's Smoke Control Panel proved the following: a. Verification of the status of all fans and dampers through illuminated LED lights, where CLOSED or OFF illuminates a red LED, OPEN or ON illuminates a green LED, and FAULT illuminates yellow or amber LED. Proper indication of initiating devices such as SMOKE DETECTION, ELEVATOR LOBBY SMOKE, WATERFLOW, MANUAL PULL STATION, etc. was observed on the FSCP. The ability to manually turn ON and OFF each smoke control fan, and open and close the associated damper. NOTE: A single switch operates the fan and associated damper of each pressurization fan. The ability to override fans and dampers during a smoke control automatic sequence. E Engineering Your Success
