3 Product description
Functional description
To prevent smoke from spreading in buildings, it is
extremely important that it is detected at an early
stage.
The RM-O-3-D duct smoke detector is used to sig-
nal to and release fire dampers and smoke
protection dampers. The duct smoke detector op-
erates on the principle of light scattering and
detects the smoke regardless of its temperature so
that fire dampers can be closed before the release
temperature is reached.
The duct smoke detector can also be used to
switch off fans in a ventilation system.
Fire dampers and smoke protection dampers close
because the power supply is cut off when smoke is
detected.
The duct smoke detector is suitable for fire damp-
ers and smoke protection dampers that are fitted
with one of the following:
• Electric spring return actuator (power off to close)
•Pneumatic actuator (pressure off to close)
•Electromagnet

commissioning
A functional test should be carried out before com-
missioning, then every 12 months and after any
modification, e.g. repair.
Without smoke
Press the test/reset push button on the duct smoke
detector or in the engineering room (option).
The voltage supply to the smoke detector which is
attached to the fire damper or smoke protection
damper is interrupted, and the damper closes as a
consequence.
Once the push button has been released, the
damper OPENS, either by means of a spring return
actuator or a pneumatic actuator.
Note
Fire dampers whose release mechanism
includes electromagnets can be opened
manually.
With smoke
Spray test gas into the duct through the opening
right next to the duct smoke detector
If the threshold value is exceeded, the voltage sup-
ply to the duct smoke detector which is attached to
the fire damper or smoke protection damper is in-
terrupted, and the damper closes as a
consequence.
To reopen the damper after the sensor head has
become free of smoke, press the test/reset push
button on the duct smoke detector.
Once the push button has been released, the
damper OPENS, either by means of a spring return
actuator or a pneumatic actuator.
Note
Fire dampers whose release mechanism
includes electromagnets can be opened
manually.
All operating, warning and alarm functions are de-
scribed on page 4.

Danger of electric shock! Do not touch any
live components! Electrical equipment
carries a dangerous electrical voltage.
• Do not open the casing for cleaning.
• Do not use any liquids near the duct
smoke detector.
If the contamination is > 70% (yellow LED is illumi-
nated) the duct smoke detector should be cleaned.
• Clean it with compressed air that is free from oil
or water.
Should this not suffice, the sensor head has to be
replaced (order no. M536HC7).
•Remove contamination from the mesh filter on
the air inlets.

• Turn the sensor head on the base to engage it
with the base.
• Turn the sensor head clockwise until it clicks into
place (you should hear this).
Note
A functional test is required when the sen-
sor head has been replaced.

Danger!
Danger of electric shock! Do not touch any
live components! Electrical equipment
carries a dangerous electrical voltage.
•Only skilled qualified electricians are al-
lowed to work on the electrical system.
•Switch off the power supply before work-
ing on any electrical equipment.
Regular care and maintenance ensure operational
readiness, functional reliability and long service life
of the duct smoke detector.
Maintenance must comply with EN 13306 and DIN
31051.
The system owner is responsible for maintenance.
The system owner is responsible for creating a
maintenance plan, for defining the maintenance
goals, and for the functional reliability of the equip-
ment.
Maintenance
The sensor head has to be replaced after 8 years

All the other parts of the RM-O-3-D duct smoke
detector are not subject to wear and hence mainte-
nance-free.
Inspection
Duct smoke detectors must be inspected before
commissioning and after any modification.
After that, the functional reliability of the duct
smoke detector has to be examined with a test gas
or smoke at least every 12 months. Local require-
ments and building regulations must be complied
with.
The test of every duct smoke detector must be doc-
umented and evaluated. If the requirements are not
fully met, suitable remedial action must be taken.
Repair
For safety reasons, repair work must only be car-
ried out by expert qualified personnel or the
manufacturer. Only original replacement parts are
to be used. A functional test is required after any
repair, see "Functional test/
commissioning" on page 11.
