Periodic Maintenance
Manufacturer Recommended Service
Intervals
•
After commissioning and handover (see DW145 check
sheet), in order to remain compliant with 15650:2010,
we recommend that you follow a regular service and
inspection programme to ensure correct operation
of dampers in the event the damper is required to
actuate.
• In addition to regular physical inspections (in
accordance with 15650:2010) we recommend using a
dedicated damper control panel with a digital reporting
mechanism (such as an Actionpac LNS system) to
frequently monitor and report on regular remote
damper testing.
• Ensure maintenance is performed in line with the latest
best practice and relevant local or specialist guidance.
• Our recommended service intervals for life safety
products are as follows:

BS EN 15650:2010 - Ventilation for Buildings
- Fire Dampers
•
Section 8.3 states regular testing/ inspection should
be undertaken to meet regulatory requirements, or at
intervals not exceeding six months.
•
A comprehensive example of the maintenance
procedure is given in Annex D of the standard. Some
automatic systems may allow more frequent testing
(48hr or less) and this may be required by a national
standard.
Approved Document B, Volume 2
• Clause 10.12 states adequate means of access must be
provided to allow inspection, testing and maintenance
of both fire damper and its actuating mechanism.
BS 9999:2017 - Code of Practice for the Fire
Safety in the Design, Management and Use
of Buildings - Annex I
Smoke Control Systems
• For means of escape states actuation of the system
should be simulated once a week. It should be ensured
that any fans and powered exhaust ventilators operate
correctly, smoke dampers close (or open in some
systems), natural exhaust ventilators open, automatic
smoke curtains move into position, etc.
Three Monthly
• In addition to the checks recommended in V.2, V.3 and
V.4, the actuation of all smoke control systems should
be simulated once every three months. All zones should
be separately tested and it should be ensured that any
fans and powered exhaust ventilators operate correctly,
smoke dampers close (or open in some systems) etc.
Yearly
• In addition to the following checks should be made
for annual inspections and tests of the following to
be carried out by competent persons, for any defects
to be logged and the necessary action taken, and for
certificates of testing to be obtained.
–
Fire detection and fire alarm systems;
– Self-contained luminaires with sealed batteries, if more
than 3 years old;
– Sprinkler, drencher and watermist systems;
– Smoke ventilators and smoke control systems;
– Fire dampers
BS 9999:2017 - Code of Practice for the Fire
Safety in the Design, Management and Use
of Buildings - Annex W
• Maintenance of air conditioning and ventilation
equipment including air filters, motors, fire dampers
and their controls, smoke detectors and alarms is
of paramount importance both in preventing fire
and in ensuring that measures taken to mitigate
its consequences are effective when needed.
Arrangements should be made for all fire dampers to
be tested by a competent person on completion of the
installation and at regular intervals not exceeding 2
years. They are to be repaired or replaced immediately
if found to be faulty. Spring operated fire dampers
should be tested annually and fire dampers in dust
laden and similar atmospheres should be tested much
more frequently, at periods suited to the degree of
pollution.
