Bosch Sicherheitssysteme: updated the fire detection system at Barthels-Feldhoff Textilwerke

Bosch Sicherheitssysteme: updated the fire detection system at Barthels-Feldhoff Textilwerke. Bosch Sicherheitssysteme has updated the fire detection system in use at the Barthels-Feldhoff Textilwerke in Wuppertal, Germany. Around 300 fire detectors and three 2000 Series SRT Universal Fire Panels operating in a loop now ensure the safety of people and property on site.

All machine shops and offices at Barthels-Feldhoff are monitored, and the existing smoke and heat exhaust units, air conditioning and ventilation systems and operating equipment control systems have been integrated into the fire alarm system. The Bosch 500 series fire detectors used in this installation monitor material and yarn production and are virtually unaffected by dust and lint.

Barthels-Feldhoff was founded as a thread mill and dyeing works in 1829 and manufactures narrow and high-tech textiles. The company has been braiding since the middle of the 19th century and ribbon weaving since the Second World War.

Braiding and dyeing, along with milling and ribbon weaving, are today the core competencies of the company in the production of narrow textiles for various industrial applications. A second focal point is supplying insoles and packaged shoestrings to the European market.

Dust in the Wind

When textile materials and yarns are manufactured and processed, small material and dust particles are produced. This poses a particular challenge for reliable fire monitoring using smoke detectors because these particles get everywhere, even into the detection chambers of detectors.

Conventional fire detectors with open detection chambers can only operate reliably in such tough environmental conditions for a very short time. Due to the fine dust particles and the high lint levels in the ambient air, even fire monitoring with smoke extraction systems would only be possible at great cleaning expense.

The 500 series fire detector is the perfect solution for production environments such as these. It detects smoke via two measurement sections outside the housing, meaning that there is only need for a virtual chamber.

Unobtrusively flat, flush mounted and fitted with a smooth, tough upper surface, the detectors are virtually unaffected by dust, fibres and foreign objects. In addition, each detector continuously checks its contamination level and triggers a fault message if any impairment is detected.

Fault-free operation of the fire detector can be ensured by cleaning its surface regularly with a micro fibre cloth. The high reliability of these fire detectors is also due to the intricate optical systems, electrical filters and digital signal processing system that Bosch has developed through years of experience with professional fire detectors.
