Dear Mr. Smith:
Zari Consulting Group, Inc. has conducted the special inspection services for the smoke control system for the North Tower and Mid-Rise located at 1000 Market Street. Based on our testing, we have the following findings regarding the performance and functionality of the new smoke control system:
- Fans and dampers functionedappropriately, and accurately.
- Upon fire alarm activation within the building (smoke detectors, duct detectors, waterflow switches), the smoke control system automatically configured to the appropriate event.
- The exhaust airflow data recorded on smoke control exhaust fans was found to meet the requirements of the Acme Associates Smoke Control Rational Analysis.
- The differential pressure data recorded from the vestibules to the corridorswere found to be a minimum of +0.05 inches of water column. The differential pressure data recorded from the stair enclosure to the vestibules were found to be +0.05 inches of water column per the California Building Code (CBC) Section 909 and Acme Associates Smoke Control Rational Analysis.
- The differential pressure data recorded from fire floors to floors above and below was found to be a minimum -0.05 inches of water column.
- Door opening force measurements were taken at all egress doors and were found to be less than 30 pounds of force with the smoke control system operating.
- Full testing of the Firefighters Smoke Control Panel, proved the following:
a) Verification of the true status of all fans and dampers through illuminated LED lights, where NORMAL status illuminates white, CLOSED or OFF illuminates a red, OPEN or ON illuminates green, and FAULT illuminates yellow or amber
b) The ability to turn on and off the smoke control fans
c) The ability to close and open dampers
d) The ability to override fans and dampers during a smoke control automatic sequence
- An emergency power test was conducted at the facility. This test proved that emergency power is provided to all smoke control equipment, and that the smoke control system aligns correctly upon activation of the emergency generator. This test further proved that the generator is capable of smoke control system loads.
- Loss of belt conditions on each smoke control fan created a FAULT condition on the Firefighters Smoke Control Panel, indicating that the fans were running but the air was not being displaced.
- A UUKL weekly self-test was performed to verify that the smoke control system is always operational. If a smoke control system component fails during the UUKL weekly self-test, the Fire Alarm Control Panel recognizes it as a TROUBLE signal and the system prints out a report clearly indicating the failure location.
- Activation of the maintenance disconnects and main breakers verify fans stop running and FAULT conditions illuminate the Firefighters Smoke Control Panel.
- Correct labeling, as indicated on the Firefighters Smoke Control Panel, has been provided for all smoke control fans and their associated maintenance disconnects.
Based on the findings above, at this time Zari Consulting Group finds the smoke control portion of the 37-Story and 24-Story Towers to be substantially complete for the Fire Marshal to issue a Temporary Condition of Occupancy (TCO). The final Smoke Control Commissioning Report will be issued to the Fire Department upon its completion.
