As part of Borg Warner’s development programme a new facility was required in Bradford, West Yorkshire where the design and testing of prototype Turbo Chargers takes place. Tecserv UK was approached to develop an Automatic Fire Detection and Fixed Fire Extinguishing system to this facility to comply with their insurance and operational requirements.
The brief was to develop a reliable and effective system for this challenging environment whilst minimising down time and unwanted alarms. The Test Cells under normal operation provide many of the detectable effects of fire, with the potential for smoke, heat and flame to be present. They are also classified as hazardous, requiring both flameproof and intrinsically safe equipment.
The solution was the use of various innovative detection technologies including Triple Infra Red Exd Flame Detection, Intrinsically Safe Optical Smoke and Fixed Temperature Heat Detectors, operating on a coincidence basis so that the activation of one detectable effect provides a local alarm for operators to act upon, with the second providing automatic shut down of the facility and coincidence operation of the IG541 extinguishing system generating a total flood of the area.
In addition to the Fire Detection System there was also a requirement for a Flammable Gas Detection system to detect any leakage of fuel that would also initiate a safe shut down of the facility.
