A60 Marine
Fire Damper
With ATEX rated
Electrical
(Schischek) Actuator
1. Description
The actionair Marine Fire Damper is tested and approved for
fitting to class A-0 A-15 A-30 A-60 divisions (bulkheads and
decks), when suitably insulated.
A-0 does not require any insulation to the casing.
2. Tests, approvals and certification
Lloyds Register Approved.
DNV-GL Approved.
ABS Approved
USCG Approved.
Transport Canada approved.
MED Marine Equipment Directive Compliant.
Fire tested to the latest IMO FTP code & in compliance with the
international convention for the safety of life at sea (SOLAS)
Sira certification (Ex) category 2 equipment
Corrosion Tested - EN60068-2-52 severity 2 conditions
Vibration Tested – EN60068-2-6 (5Hz to 350Hz @2g)
3. Health and Safety
Care must be taken when installing and inspecting dampers,
as they are likely to close without warning due to loss of
electrical power, or a temperature rise in the ductwork. This is
their prime function.
Do not introduce any items, fingers or limbs between the
blades.
Larger dampers are heavy and must be handled in accordance
with current local regulations and good practice.
All wiring should be carried out in accordance with the wiring
details provided, to the IEC regulations.
4. General Information
The actionair Marine Fire Damper is suitable for both vertical
and horizontal applications, with airflow in either direction.
The dampers tested to IMO fire test procedures Code, Annex 1
Pt 3, are normally open, and fail-safe to the closed position. The
actionair Marine Fire Dampers are supplied with the blades in
the fully interlocked closed position to avoid damage during
transit and installation. It is recommended that the dampers
remain closed until actual date of commissioning. All fire
dampers are life safety products and must be treated with care
during handling, storage and installation.
Actionair Marine Fire Dampers are designed for applications in
normal dry filtered air systems and should be subjected to a
planned inspection programme.
5. Installation - see below.
6. Maintenance & Cleaning
Dampers are supplied in two casing and blade material
options: -
1/ Galvanised Steel casing and 430 Stainless steel blades, only
suitable for installation in dry filtered systems.
2/ 316 Stainless steel casing and blades and drive - more suited
for corrosive conditions, but even this will rapidly corrode and
fail if not properly maintained, when used in air intake systems
at sea. The addition of a mist eliminator is highly recommended,
and access must be provided for maintenance.
7. Testing
Two levels of testing exist.
Routine testing - Monthly, or in accordance with maintenance
programme, release and reset damper (via control system or
ETR test switch). Check remote indication or visual check of
mechanical pointer as appropriate.
Visual check at damper - At commissioning and at least once
a year, check damper operation by removing and
re-applying power to actuator. (via ETR test switch).
Visually check blades for damper closed and open positions.
Prove remote indication if applicable.
8. Routine Maintenance
Depending upon environmental conditions, each damper will
merit its own cleaning regime. Particularly hostile areas.
‘Frequency of maintenance’ should be determined by
collecting historical data from previous visits, and for this
reason, commence maintenance programmes.
Dampers in ‘Dry Filtered Air’ require very limited maintenance.
When exposed to fresh air intakes and/or inclement conditions
this may require monthly cleaning and lubrication maintenance
to be performed.
9. Cleaning
Using light lubricant, clean all exposed surfaces, using a cloth.
Remove all traces of surface staining, as this will deteriorate
further causing deeper material corrosion.
For 316 stainless steel blades and case, pay specific attention
to the blade rivets where crevice corrosion will cause rapid
failure of blades if not kept in check.
If damper is stiff to operate lubricate blade ends, open and
close damper successively until the damper moves with ease.
(This may necessitate removal of the actuator and operating
the blades manually by the drive shaft).
Refit actuator and re-test.
Clean off excessive lubricant.
