Function test
Check if the central unit functions properly after successfully
installing all components (fire pushbuttons, smoke or heat
detector, drives, ventilation pushbuttons, etc).
- Switch the 230 V AC power supply on and slip on the
battery packs.
- The green LED on LAD 9 is lit.
- All other modules must show only green LEDs.
- Push the alarm button (red) on the fire pushbuttons to turn
the system on. The red LEDs in the fire pushbutton and on
the RWA 9 are lit.
- Check if all windows of the corresponding fire group are
opened all the way. Afterwards, close the windows by
pressing the RESET button (black) in the fire pushbutton.
- Use a smoke detector test control unit to trigger the
smoke detector; the (red) LED on the RM 9 will be lit, and
the windows will open.
- When using test gas for checking the smoke detectors,
you must press and hold the RESET button on the RWA 9
module or the fire pushbutton for 10 seconds in order to
set the RM 523 smoke detector to revision mode.
- Check the ventilation pushbuttons by pressing the OPEN,
STOP, and CLOSE buttons.
- Switch off the 230 V AC mains supply; the green LEDs will
turn off, and the yellow malfunction LEDs will start flashing
in the event of a malfunction.
Elimination of fault
functions
Green display LEDs on the load module are not lit
Error source:
- 230 V AC mains supply not connected

- Connection to battery packs is not established
Error message “Mains / battery fault“ does not appear
- monitoring takes place cyclically approx. every 25 minutes
- it is necessary to wait for the appropriate time

Error source:
- Malfunction in the area of the fire pushbutton
- Break or short circuit in wire SHEV “OPEN” or “CLOSE”;
red LED is lit
- Alarm was triggered

is not lit
- 10K terminal resistor not installed in smoke detector
- Break or short circuit in smoke detector wire
- System runs on emergency power
Display in group control module – yellow LED is
lit or flashing
Error source:

Display in wind/rain module – red LED is lit
Error source:
- The wind sensor has triggered a wind alarm
- The rain sensor was triggered
Displays in potential-free output module – green LEDs
are lit
Error source:
- The relays have been actuated by the signals issued by
the smoke and heat exhaust ventilation or ventilation bus
Displays in potential-free input module – green LEDs
are lit
Error source:
- The relays on the module have been actuated by the
signals issued by external devices
Care
Check all devices and cable connections for external
damage and dirt. The operability of smoke outlets, central
control units, fire pushbuttons, ventilation pushbuttons, etc.
must not be affected by, for example, structural measures
or stored goods.
Maintenance
Smoke and heat exhaust ventilation systems must be
serviced at least once a year by a company specialised in
smoke and heat exhaust ventilation and in accordance with
all statutory regulations (building code and state building
regulations).
To guarantee a reliable emergency power supply, have the
used battery packs checked and, if necessary, replaced on
a regular basis. The battery packs must be replaced no later
than every 4 years. Dispose of the battery packs properly as
required by all applicable legal regulations.
The inspection plate on the central unit must be renewed,
and a control book must be kept.
We recommend that you conclude a service contract.
Maintenance
If components have to be checked, repaired or replaced,
please contact the manufacturer. Use only original spare parts.
Modifications of connections are permitted only within the limits
of the connection options.
Disposal
Dispose of this product, when it has reached
the end of its service life, in accordance with
the provisions of the Electrical and Electronic
Equipment Act.
Before working on electrically powered windows and dome
lights, make sure to set them to the desired position. They
must be disconnected via isolating link at all poles and
safeguarded against unintentional re-starting. The isolating
link must be clearly marked. This step allows you to
disable the ventilation function while performing work on
the windows.Observe the maintenance and operating
regulations for power-controlled windows, doors, and gates.
