- A fan continuously draws air from the protected area through the detection chamber
- Once inside, particles pass through the laser beam while the photo collector measures reflected light from the particles.
- The collector counts the number of discrete particles to determine the level of smoke concentration. A particle size discriminator prevents large particles, such as dust, from contributing to the smoke concentration.
- Unlike other high-sensitivity smoke detection systems, particle concentration is absolutely critical.
- Because they detect both the number and size of particles, it can actually distinguish particles of combustion form dust and other airborne contaminants that routinely trigger nuisance alarms in traditional spot detectors.
Jim O'Connell, Director of Business Development of ORR Protection sits down with Lee Kaiser to talk about high-tech fire protection systems in industries like telecommunications, his journey at ORR, and the future of mission critical fire protection.
