For installing trunking units with fire barriers, the following points
must be observed in addition to correct positioning:
• Horizontally mounted busbar runs must be supported by a
fixing bracket fitted approx. 500 mm before and after the
structural element they pass through.
• The space $ surrounding the busbar trunking unit within the
structural element it passes through must be packed with
mineral-based mortar or ZZ fire barrier sealant TS90.
• The gaps between PROMATECT-H(L) panels, the busbar
trunking unit and the structural element must be sealed with
ZZ fire barrier sealant TS90 (included as standard if panels are
required).
• The mortar or ZZ fire barrier sealant TS90 must conform to the
applicable regulations for establishing fire resistance rating or
the construction of the wall or ceiling (e.g. DIN 1045 and
DIN 1053 Part 1).
• The installation must be carried out according to pertinent
building regulations (included as standard).
