Bisson aspirating pipe | grey, ABS | 25mm × 2.5m | EN 54-20

Bisson 25 mm ABS pipe is designed solely for the sampling pipework of aspirating smoke detection systems. The pipe is grey with black printing "FIRE ALARM AIR SAMPLING PIPE – DO NOT CUT OR PAINT" and has been tested by BSI to EN 54-20:2006 clause 5.7. The pipe must not be bent or painted and is not installed in direct sunlight. Pipe clips are fitted every 800 mm (closer at higher temperatures), and expansion joints are used where the ambient temperature is outside 15–25 °C. Cut the pipe with sharp plastic pipe cutters and clean it with soapy water only.
