What is Air Sampling Fire Detection?
Air Sampling, also know as aspirating, fire detection utilizes an aspirator, and a supervised sample pipe network to return air samples from an environment that is being protected, back to a detection unit for analysis.  The air sample is drawn into the pipe network through either holes drilled in the pipe, a capillary or extended drop from the pipe, or sample heads which can be either adjustable or non-adjustable.  Each of these methods use flow calculations to determine sample hole sizes, pressure drops and acceptable pipe lengths to be sure the system meets NFPA guidelines.  Below are details for each of these methods.

Networking ProSeries Detectors
ProSeries detectors are easily networked without needing any additional hardware or software.  Any detector on the network with a display can be the network hub.  Free CirrusPro software and a laptop can easily be used to program all the detectors on a network, even if none of the units have a display.
What types of air sampling systems are there?

Low Pressure
"Laser Style" systems utilize a 3/4" sample pipe in either a straight run, serpentine or U-shape pattern.  The sample pipe configuration for the ProSeries low pressure system is identical to those of laser style systems making it a drop in replacement.  Detector coverage is up to 20,000 sqft., and up to four zones.

High Pressure
"Engineered Style" systems utilize a combination of 1/2", 5/8", 3/8", and 1/4" pipe for its air sampling system.  These high pressure systems utilize a powerful centrifugal fan which allows more flexibility in design, greater distances, larger detection areas per unit, and can easily handle extreme pressure differentials.  Up to 43,200 sqft. can be covered from one four zone detector.
