Maintenance Notes
FSD-C Series fire/smoke dampers are designed for normal dry filtered
air systems. A programme of planned inspections should be carried out
to include full operational checks, correct interface with, and function
of, any control systems, cleaning and light lubrication.
As a guide, this should take annually. Please refer to BSB Operating and
Maintenance instructions.
Reference should be made to BS 5588-12 and BS 9999 for more
information.
Records of damper installation and position shall be kept. Records of
the condition of the dampers and their functionality/repair etc should
be kept as these products come under the requirements of the
Regulatory Reform (Fire safety) Order (RRFSO).
These inspection and maintenance programmes may need to be
repeated more regularly if the dampers are exposed to
inclement/dusty conditions or fresh air intakes and the frequency of
such checks should be developed based on site experience.
