Product maintenance
Smoke control dampers must form part of a professionally designed Smoke and Heat Exhaust Ventilation System (SHEVS) that
will be specially suited to an individual buildings size, usage and structure. SHEVS are Fire Safety Installations and it is essential
they are subject to the routine inspection and maintenance requirements of the country of installation of the SHEV system. For
example, BS7346 part 8, NF S 61-933 and EN 13306. Kamouflage MP dampers are virtually maintenance free, however, they will
require occasional operation and maintenance as part of a system specific routine operational test and maintenance procedure. It
is recommended that as part of the system testing and maintenance procedure that different individual dampers are operated at
each system test such that each damper within a system is inspected, checked and tested at least once in any 6-month period. The
following instructions are a general guide and our recommendations to the procedures required: a) Operate each ventilator at least
once; checking that the unit opens and closes fully. b) Visually observe the control mechanisms ensuring the devices are in place and
are not obviously damaged or obstructed. c) Inspect each ventilator in its open position to check that the intumescent fire seals and
smoke seals between the vent frame and doors are not damaged and are securely attached. Wipe any dirt build up from the seals.
Inspect the door leading and trailing edge seals and lightly lubricate with a machine oil and a silicone grease to the release latch.
