Any pump enclosures and trunking should be made from materials specially designed for sprinkler boxing,
for example:
FR sprinkler boxings (FRSB) is suitable for use in internal dry conditions as defined in EN622 part 5.
Materials of this type are suitable for use in Hazard Class 1 of EN 335-3. In addition to being manufactured
from FSC® certified 12 mm thick moisture resistant MDF board the material used in our flame retardant
sprinkler boxings is also compliant with Euroclass B standards. The range of dedicated accessories available
for FRSB products are also manufactured from the same Euroclass B compliant material. All paint coatings
used on FRSB products are coated with flame retardant BS EN Class B s1 d0 paint.
