SERVICE
CHECKING THE FUNCTION, CLEANING, REPAIR
Installation information
The assembly must be made in a way that the inner viewing,
cleaning and maintenance of the smoke damper is possible. To
this end, suitable inspection openings must be provided in the
connected smoke extraction ducts, if required. The connection
to smoke extraction ducts made of wall boards is done accord-
ing to inspected duct-specific constructions. The connection to
inspected sheet steel ducts or flexible connection pieces is
done via the profiled mounting frame type PAR.
Regulations for use and maintenance
- The operator of the smoke extraction installation must en-
sure that smoke extraction dampers are always kept in a
ready-to-operate state and are maintained.
- Smoke extraction dampers must undergo maintenance at a
six-month interval. If two consecutive inspections do not
show any malfunctions, the maintenance interval of the
smoke extraction dampers can be reduced to once a year.
- An inspection report must be produced, and the documents
must be kept by the operator of the smoke extraction instal-
lation.
o
The smoke extraction dampers must be installed in ac-
cordance with the technical documentation, installa-
tion, mounting and operating instructions.
o
The work must be carried out by specialised compa-
nies only.
o
Observe general accident prevention regulations.
o
The smoke extraction dampers must be installed such
that they are accessible.
o
For internal inspection and cleaning of the smoke ex-
traction dampers, install inspection openings in the
continuation connection lines.
o
The cover of the temperature-resistant actuator hous-
ing can be dismounted for electrical wiring and must
be properly remounted (screwed) once the wiring is
completed; the actuator itself is maintenance-free.
o
The electrical line installation must be at least E30, ac-
cording to DIN 4102-12.
o
All electrical connections between actuator and power
supply must be made according to the valid VDE guide-
lines.
o
Observe the general guidelines for service according to
DIN 31051 and EN 13306.
o
For and after commissioning, the function of the entire
smoke extraction system (interaction of all compo-
nents) must be regularly checked and documented in
writing.
o
The owner or operator must check whether the mini-
mum requirement for his operation is met.
o
The function can be checked from the central unit.
o
Repair work can be carried out only after consultation
with the manufacturer.
1 - Inspection for commissioning on site
o
Check the smoke extraction damper for damage.
o
The smoke extraction damper must be installed in ac-
cordance with the technical documentation, installa-
tion, mounting and operating instructions.
o
Dismount the cover of the temperature-resistant actu-
ator housing.
o
The electrical wiring is done by a skilled electrician. Ca-
ble is inserted via a bore of exact fit = ø E90 or ø E30
cable through the side wall of the temperature-re-
sistant actuator housing.
o
Damper is in closed position, damper blade "CLOSED".
o
Connection to electric circuit
o
*Motors EK10 (SEL 1.90; 24 V AC/DC) / EK11 (SEL 2.90; 230
V AC): 2-point activation of the smoke extraction damper.
o
*Motors EK12 (SEL 1.90 SLC; 24 V AC/DC) / EK14 (EK12
+ SPMa-1SR): activation via 2-wire connection (SLC sys-
tem) only in connection with communication device
e.g. SPLM-4S 0SD Mod / SPMa-1SR (component of
EK14).
o
From the switch cabinet, give pulse for open position
(smoke extraction) or closed position (fire).
o
Damper blade moves to open/closed position; the
movement is controlled by motor.
o
Limit switches integrated in the actuator indicate the
open/closed positions.
o
Open / close running time < 60 sec.
o
*Torque monitoring: SLC system at least 40 Nm.
o
Screw the cover of the temperature-resistant actuator
housing again.
2 - Service for commissioning on site
o
Remove / clean dirt / soiling detected during inspec-
tion.
3 - Inspection after commissioning – every 6 months / once a
year
o
See Inspection for commissioning.
o
Functional test of the smoke extraction damper on
site.
o
Functional test by external monitoring.
4 - Service after commissioning depending on system equip-
ment and operating conditions
o
Internal inspection
o
Remove / clean system-specific dirt / soiling which af-
fects safety function.
Measures to be implemented for service must be docu-
mented in writing and provide proof.
5 - Repair
o
Repair work must be carried out after consultation
with the manufacturer.
