SmokeCommand MCD
Commissioning and
periodic maintenance
Access for Inspection
• It is imperative that the smoke control damper must
be fitted in a manner that means it is accessible for
maintenance.
Maintenance Procedure
• Smoke control dampers must be inspected prior
to commissioning and tested immediately post-
commissioning.
• Check the actuator wiring, end-switch wiring and check
the conditioning of the blades and seals for any potential
damage.
• The units should be carefully inspected and cleaned of
dust and debris by wiping over exposed surfaces with a
light oil.
• Actuators should be used to check the operation of the
damper to ensure both fully open and closing positions
are reached.
• The open and closed positions can be checked by the
actuator end switches. A visual check should also be done
to confirm the actuator is attached to the damper and the
end switches correspond to the damper blades position.
• Confirm that the damper fulfils its function as part of
the smoke control system and leave the damper in its
standby position.
• Note: Units operating in dusty atmospheres, should be
checked often to suit the severity of the conditions.
Frequency of Operational Checks
• Following EN 12101-8:2011 Section 8.3, regular testing/
inspection should be undertaken to meet regulatory
requirements, or at intervals not exceeding six months.
Some automatic systems may allow more frequent
testing (48hr or less) and this may be required by a
national standard.
• Units associated with systems may be required to be
checked, as part of the system, as often as once per week
or month to ensure ongoing confidence in the life safety
system. This may be seen as analogous to fire alarm
systems.
• In addition to the checks recommended above, 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.
• 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.
• Arrangements should be made for all SmokeCommand
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. SmokeCommand

dampers in dust laden and similar atmospheres should
be tested much more frequently, at periods suited to the
degree of pollution.
Effects of Corrosion
• The effects of corrosion on the damper could prevent it
from operating correctly when required, compromising
the smoke extract system and/or breaching
compartmentation.
• Checks for corrosion must be done during the
maintenance inspection of the dampers by a suitably
competent person, with any observations documented,
the person with responsibility for the building notified
and remedial actions taken if required – this may
include replacement of the damper if the corrosion is
sufficiently advanced that damper performance could be
compromised.
• Should signs of surface corrosion start to appear, increase
the frequency of the inspection and monitor for further
changes, documenting the changes in the inspection log.
Check the rest of the system for further signs of corrosion,
and try and identify and mitigate the root cause.
• Specific areas of concern that should be inspected at each
maintenance interval with regards to damper corrosion
and associated function include:
• Rivets
• Holes
• Clinches
• Failure to follow the maintenance instructions at the
frequency specified could shorten the life span of the
product.
Mode SCHM5-2P PTC and
SCHM6-2P PTC
Overview
• Drive open / Drive closed. 60 seconds operation.
• This new 2 position control mode has been developed
to provide drive open/ drive closed damper operation
and it brings Actionair dampers in line with imminent
European Standardisation for fire and smoke control,
where for a given smoke control philosophy, or smoke
source, a damper may be required to open or close
to vent or contain the smoke. For EN 12101-8:2011
compliance actuators require powered opening and
closing functionality.
• For part EN 12101-8:2011 compliance fail safe close is
not applicable. For smoke control operation the damper
needs to be able to remain under powered control.
• As with all PTC actuators, this series uses the snaplock™
interface. All modes have LSF cables. HOT400/30
classification means SmokeCommand can cycle and
adjust position for 30 minutes at 400°C.
Thermal Enclosure for Hot Modes
• Actionair use a proprietary thermal enclosure that is both
lightweight and offers superior performance over other
thermal enclosures. This enables the SmokeCommand
damper range to perform to HOT 400/30.
