From time to time, we feature frequently asked questions about FARS. This month, we're focusing on air quality and reliability.
Q. How is air quality ensured?
A. FARS are clean, dry, closed breathable air systems. In accordance with 2015 IFC Appendix L, all FARS are equipped with an air monitoring system, which allows the Fire Department to monitor the system's moisture, carbon monoxide and pressure 24/7.
“L104.15 Air monitoring system. An approved air monitoring system shall be provided. The system shall automatically monitor air quality, moisture and pressure on a continual basis. The air monitoring system shall be equipped with not less than two content analyzers capable of detecting carbon monoxide, carbon dioxide, nitrogen, oxygen, moisture and hydrocarbons.”
The system is monitored via the building's fire alarm system and panel as a supervisory signal. FARS can also be monitored around the clock by the private sector via web-based monitoring. Should any air quality readings exceed IFC 2015 Appendix L or NFPA 1989 requirements, signals are immediately sent to the fire alarm panel, activating audible and visual alarms. The AHJ and private sector monitoring companies are notified of the supervisory signal and respond according to the AHJ protocol.
