Early Warning Smoke Detection

Early Warning Smoke Detectors are equal to and often better than a human in detecting fire. These systems use a highly discriminating detection chamber. Early Warning Smoke Detectors are wall-mounted extra-sensitive smoke detection units that are connected to as many as four zones of sampling pipes in each detector. Holes of pre-determined sizes are drilled into CPVC sampling pipe. An aspirator in the detection unit draws air samples from the holes along each sampling pipe into the detection chamber.

The Early Warning Smoke Detection concept works by continually drawing ambient air through sample points in a pipe network. Upon entering the unit, the sampled air is filtered via the dual-stage filter, then it is passed into the detection chamber where light scattering technology detects the presence of very small amounts of smoke. As the amount of detected smoke increases, the LED graph provides the user with an instant understanding of a smoke event, even from a significant distance. Detector status information is communicated externally via relays or optional interface cards.
