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.
