Description
Description
The FSW800B Seriesair-flow monitorprovides a simplebut reliable alternativeto indicate positive ornegative air flow of fans.When properly installed andconnected in series with an optical(i.e. LED) or audible signalingdevice, a bi-directional switch willactivate an electrical contact if theair flow of the fan falls below 8.2 ft/s,thus either turning the signalingdevice on or off.
