Fire damper ETPR-E-1 - Instructions for Installation, Operation and Maintenance
2
GENERAL
Fire and smoke damper ETPR-E-1 is used as a closing device for pre-
venting the spread of fire and smoke in ventilation ducts between fire
compartments. Fire dampers are equipped with fusible link and spring
mechanism for closing or with electrical actuator.
ETPR-E-1 conforms to fire resistance class E 120 / E 60 S when in-
stalled in vertical ducting and E 90 / E 60 S in horizontal ducting. Fire
damper is tested according to test standard EN 1366-2 and classified
according to EN 13501-3. ETPR-E-1 is approved for installation into buil-
ding elements made of concrete, lightweight concrete, brick or gypsum
plate walls. The damper shaft can be installed in horizontal or vertical
position. An E-classified fire damper requires fire insulation for ducts in
order to comply with the compartmentation requirement (EI).
ETPR-E-1 is CE marked.
INSPECTION
The operation of the fire damper must always be inspected before and
after installation.
Ensure that the casing is circular and that the blade moves and closes
unobstructed. Remove any construction material remains and dust from
the inside of the damper.
Function testing of the damper has to be carried out at least twice a
year.
SETTING THE DAMPER WITH THERMAL FUSE AND
REPLACING THE FUSE
Loosen the fuse screw by approximately 7 mm. By turning the setting
handle, set the blade into the “open” position. Tighten the screw by
hand. ATTENTION! DO NOT USE ANY TOOL. To replace the fuse, unscrew
the fuse screw together with the fuse. Then
install a new fuse and set the fire damper as described above.
BE CAREFUL NOT TO LET THE SPRING-LOADED HANDLE HURT YOUR
HAND.
TESTING MOTORIZED DAMPERS
Motorized dampers can be tested before connecting the electricity by
using the tool delivered with the unit, and when electricity is connected
by operating the thermal switch. Note! If you open the damper using the
tool, do not forget to release the damper back to closed position before
connecting electricity.
Electric installations are only allowed to properly trained electricians
and according to separate drawings and wiring diagrams. Damper mo-
tor wiring diagram is shown in Fig. 2.

INSTALLATION AND MAINTENANCE
INSTALLATION
To secure the performance and operation of the fire damper, it is ne-
cessary to do the installation according to these instructions and local
regulations.
Fire damper ETPR-E-1 can be fitted with either to horizontal or vertical
ducting. Max. velocity of air flow through the damper is 15 m/s, and
operation in not dependent on the air flow direction.
MAINTENANCE
The function testing interval is always determined separately for each
building, but testing must be carried out at least twice a year according
to product standard EN 15650:2010 (see example of check list beside).
WARNING! Never put your hands inside the damper while it is closing.
Clean the fire damper by means of a vacuum cleaner. Avoid chemical
cleaning agents.

The body has to be fixed firmly into building element. Damper has a
factoryfitted installation plate for mounting. Fire damper is installed into
building element according to installation drawings below.
Fire damper has to be fitted into ducting so, that it is easy to inspect
and clean.

MAINTENANCE CHECK LIST
Fire damper reference
Date of inspection
Check actuator wiring for damage (where applicable)
Check end-switch wiring for damage (where applicable)
Check fire damper cleanliness and clean where necessary
Check the condition of blades and seals, rectify and report where neces-
sary
Confirm the safety closure operation of the fire damper according to the
manufacturer’s instructions
Confirm operation of damper to OPEN and CLOSE by use of the control
system and physical observation of the fire damper, rectify and report
where necessary
Confirm operation of OPEN and CLOSED end-switches, rectify and report
where necessary
Confirm that the fire damper fullfills its function as a part of the control
system (where applicable)
Confirm that the fire damper is left in its normal working position
NOTE! A fire damper is usually part of a system. As this is the case, the
whole system should be checked as governed by the operation and
maintenance requirements for the system.
