M inten nce / Inspection
Maintenance of the smoke detection device for fire and smoke
dampers must be carried out once a year or after a fault mes-
sage, due to contamination.
Note
Installation and wiring must be carried out by authorised elec-
tricians only. The agreed regulations of the technic, safety and
accident prevention regulations as well as the VDE guidelines,
regulations of the local EVU's and the wiring instructions and
connection plans of the manufacturer, must be adhered to when
installing, wiring and commissioning. When wiring the junction
boxes, make sure to earth the shielding. The smoke detector
must be used according to this brochure description.
M inten nce instructions
The SCHAKO smoke detector type RMS
ΙΙ
-L permanently moni-
tors itself and gives an error warning to the central unit if there
is a mechanical or electrical defect or if it is too heavily soiled.
In case of a power failure of the smoke detector, a fault message
is also sent to the central unit. This permanent self-monitoring
allows a yearly maintenance interval.
M inten nce includes the following ctions:
Inspection instructions
The SCHAKO smoke detector type RMS
ΙΙ
-L permanently moni-
tors itself and gives an error warning to the central unit if there
is a mechanical or electrical defect or if it is too heavily soiled.
When a power failure of the smoke detector occurs, a fault mes-
sage is also sent to the central unit.
1. The type of use and installation situation must be checked
for the first time during commissioning and then after mod-
ification.
2. The electrical connections must be checked for correct con-
nection and perfect condition.
3. Checking whether the diode on the fitted smoke detector or
relay module flashes orange, thus signalling ready operat-
ing state.
. Electrical functionality control
The power supply of the smoke detector must be discon-
nected by removing the 9-pin Sub-D plug or by pressing the
reset button on the relay module. This causes the smoke de-
tector to send an alarm to the connected locking device,
which will close automatically. The diode on the smoke de-
tector or relay module is no longer lit. As soon as the power
supply has been restored and the alarm has been acknowl-
edged by pressing the reset button, the smoke detector
must return to the ready operating state, and the diode on
the smoke detector and / or relay module must flash orange
5. Fault control
On the smoke detector RMS
ΙΙ
-L, the transmitter and receiv-
er sensors must be covered. The diode on the smoke detec-
tor lights up permanently in orange. The fault contact
reports a fault. After that, the cover must be removed again.
The smoke detector must again return to the ready operat-
ing state, and the fault message is reset at the central unit.
6. Functionality control using test aerosols
When the smoke detector is fitted to ducts, a test aerosol
must be applied to the smoke detector through an inspec-
tion opening.. This must be done by applying the test aero-
sol to the smoke detector increasingly in pulsed form for
about 10 sec. When the alarm threshold values is exceeded,
an alarm message will be triggered, and the connected lock-
ing devices must close automatically. The diodes on the
smoke detector and on the relay module must light up in
red. After the test aerosol components in the surrounding
air of the smoke detector have decomposed to such an ex-
tent that the value drops again below the alarm threshold
value, the alarm message is still displayed on the smoke de-
tector and on the relay module. This is why the smoke de-
tector must be activated again by pressing the reset button
on the relay module. As soon as the diode on the smoke de-
tector type RMS
ΙΙ
-L flashes in orange again and the red LED
on the relay module goes out, the smoke detector is ready
to operate again.
7. Elimination of defects
If defects have been detected during maintenance, they
must be eliminated immediately. Defective components
may only be replaced with original parts delivered by SCHA-
KO. Repair of the smoke detector and of the relay module
must be carried out only by the appliance manufacturer.
If any of the connected shut-off devices are not closing,
even when the smoke detector and the relay module operate
faultlessly, then the shut-off devices themselves must be
checked.
8. If the maintenance and inspection instructions of this tech-
nical documentation are used for the annual check of the
functioning of the SCHAKO smoke detection system (RMS),
the smoke detector can remain in use until an inadmissible
deviation is detected.
