Where such equipment and ductwork is located within the exit enclosure, the intake air shall be taken. • duct smoke detectors can only detect smoke when smoke laden air is circulating in the ductwork. The international mechanical code (imc) specifies that if the space is air conditioned and the a/c unit is over 2,000 cfm, a duct smoke detector is required to be installed in the return air duct. Current requirements (using no accessories). Not a replacement for a building's regular fire detection system. Duct pressure (and fan loading) optimized to satisfy ahu with greatest demand. Duct smoke detectors are not a substitute for open area smoke detectors; Of exhaust fans, such as those in kitchen vent hoods, there are required not to be shut down, i over the years the duct detector requirements have bounced back and forth from. 606.4.2 duct systems, fan shutdown. Pcfm = power consumption (w). Cfm — cubic feet per minute db — dry bulb ddc — direct digital control dp — dew point ea 1. It basically says how powerful the fan moves if you use foil or corrugated metal ducting, it will reduce performance and it will increase the noise of your stove hood. The fan efficiency is the ratio between power transferred to airflow and the power used by the fan.
Duct pressure (and fan loading) optimized to satisfy ahu with greatest demand. To prevent false alarms the detectors should not be mounted in areas of extreme high or low temperatures, in areas where high humidity exist, or in areas where duct air may contain. Dp = increased pressure head (pa). Where such equipment and ductwork is located within the exit enclosure, the intake air shall be taken. (yes, that's 3000cfm) to find a fan big enough to do this and to determine if the duct can even withstand the pressure i need to know what my static pressure is at the very least, most codes require automatic shutdown at 2000 cfm and larger and those usually are tied to the fire alarm control system.
Smoke Damper Presentantion from image.slidesharecdn.com Since the requirement for tying in l code, shutdown of the respective air handler is only required if the unit has a discharge rate of 2000 cfm tips for using duct smoke detector code requirements effectively. Duct pressure (and fan loading) optimized to satisfy ahu with greatest demand. Dp = increased pressure head (pa). Duct smoke detectors are not a substitute for open area smoke detectors; Not a substitute for early warning detection; Nfpa 90a duct smoke detector requirements. Location requirements duct smoke detector location requirements: According to my understanding of code, duct detectors are required on the return side if the air handling unit is over 2000 cfm, this would detect smoke that is.

Dp = increased pressure head (pa). Dpin = pressure increase (in. Much of the installation will depend on what the duct. The most effective fire protection plans include detection, suppression and automatic fire and/ or smoke dampers and automatic fan shutdown in hvac systems from shafts. Auxiliary contacts for fan shutdown, etc. 6.4.2.2 return system smoke detectors are not required when the entire space served by the air distribution system is protected the capacity of air handling systems are typically rated in cfm (cubic feet per minute). 606.4.2 duct systems, fan shutdown. Minute air exchange chart for commercial and industrial applications. If operational requirements dictate, the engine may be shut down with a one minute cooling period. Current requirements (using no accessories). Duct pressure (and fan loading) optimized to satisfy ahu with greatest demand.
