Fire barrier
If the busbar trunking system is routed through a fire wall or
ceiling, a fire barrier must be fitted. Depending on the customers
requirements, Siemens offers fire barriers with a fire resistance
rating of S90 and S120.
Standard lengths, optional lengths and junction units are supplied
with fire protective equipment as specified in the ordering
data (see "fire barrier", page 5/93).
Factory-fitted equipment:
• Internal fire barriers
• External fire barriers, if required
• Documentation (certificate of approval, wall-mounted signs
and declaration of conformity), for Germany as separate kit
BD2-S90-ZUL-D or BD2-S120-ZUL-D
Mineral based mortar or fire barrier sealant (see "fire barrier" on
page 5/100) for sealing joints between the busbar trunking element
and component must be supplied by the customer.
