System Sensor Telecommunications Bell Canada

Case Study Bell Canada Duct Smoke Detectors Canada a company that supplies innovative solutions services had a problem It needed smoke detectors would provide reliable very early warning to protect telecommunications rooms high asset areas with high air Because these areas are very sensitive to particulates small traces of smoke could cause significant damage and disruptions Canada turned to System Sensor which had the product do the job its new laser based model 7251 DH intelligent air smoke detector the company latest addition to its high detection line up The product combines the System high sensitivity laser with its industry leading smoke detection capability detector not only provides early warning it screens false alarms with a set of logic algorithms It created to work in areas like rooms and server rooms which high air flow and several air per hour equipment spaces are frequently tight spot detection or air aspiration tubing in front of air equipment to monitor the air flow often creates issues potential injury and equipment damage It can also create with HVAC equipment maintenance if the narrow become partially obstructed Sensor responded to Bell Canada request for Very Warning Fire Detection performance with the conventional detection configuration Once the new duct detection was listed by Underwriters Laboratories of Canada Canada installed the duct detection system in one of the that had recently been to laser spot detection ceiling mounted detectors installed to comply with NFPA prescriptive requirements The air early detection system was based on NFPA 76 requirements determine how well the new worked Bell Canada the performance based requirements outlined in 76 Annex B types of environments different than a static air where fire generates that rises to the ceiling a concentrated form In a center the air flow causes air mixing smoke dilution That makes by any means other than detection slow less responsive NFPA 76 for the Fire Protection of Facilities requires Very Early Warning Fire to detect small incipient stage malfunctions that could to fire conditions A manual response in this early stage terminates the malfunction early warning fire DNRHS high sensitivity duct detector provides very early of fires to protect high assets and mission critical from fire and the spread damaging smoke through management systems The intelligent laser sensor detect miniscule amounts of at air velocities from 300 to feet per minute ideal for environments with high velocity air changes And its unique pivoting housing fits square and rectangular footprints so you can be sure the will fit your installation more information visit www systemsensor com flex elevated air flows and in some other locations the smoke not have an opportunity to rise to ceiling based detection makes the detection of the air flow at return grilles a very part of the smoke detection system Very Early Warning Detection requirements for return air call for an air aspiration or spot detector for every 4 square feet of return grille area often results in an overabundance of detection technology vulnerable placement areas The 7251 DH has been upgraded to and replaced by the InnovairFlex DNRHS high sensitivity duct detector System Sensor All rights reserved Product specifications subject to change without notice 6 10 2429
