Allied Fire & SafetyEarly Warning Fire Detection Systems
Early warning Fire Detection is a fire alarm system composed of specialized detection which may include air sampling, Laser-view, UV or IR Type detection. This type of detection is designed to detect a fire in its earliest stages and can respond 50-100 times faster than standard Photoelectric or Ionization 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.
Early warning Fire Detection systems should be considered for any area where "down time" is critical and must be avoided.
