Product description

The retrofittable radio module sends and receives alarm signals in conjunction
with the smoke detector FMR 3026. As soon as the smoke detector emits an
alarm via the network terminal, the radio module sends the alarm via radio to
all radio modules in its radio group. This process involves the radio modules
that are in range forwarding an alarm message within the respective radio
group once. This alarm message even bypasses transmission paths that are
particularly long, such as from the basement to the top floor via the ground
floor, for example. When the alarm is no longer active at the smoke detector,
the radio modules cancel the alarm after a short time (up to approximately 30
seconds). Up to 30 radio modules with smoke detectors can be assigned to a
radio group. Up to eight independent radio groups can be programmed so that
modules do not interfere with each other within blocks of flats, for example.
The radio modules assigned to the same radio group must only be located
within one building. It is not permitted to install some of the radio modules
in neighbouring buildings.

Operation/testing

Each detector/radio module that receives a radio signal directly from the signal
origin in the same radio group forwards this signal forwards once automatically.
To avoid data collision, the signal is forwarded only when the radio channel
is free. Each detector sending a signal acknowledges that the signal has
been forwarded by emitting 3–4 short sounds at intervals of approximately
five seconds. When the channel is free again, the next detector/radio module
forwards the signal and acknowledges it, and so on. When a battery is
drained, this is displayed locally on the smoke detector, as described in the
instructions for the smoke detector. In addition, the radio module automatically
measures the battery approximately every 20 minutes. The drained threshold
value is set to approximately 6.9 V, so that the message will be sent only after
the fault message is displayed by the smoke detector itself. Each detector
sending a battery signal acknowledges that the signal has been forwarded by
emitting 3–4 short sounds at intervals of approximately five seconds. When
the channel is free again, the next detector/radio module forwards the signal
and acknowledges it, and so on.
Note: Follow the instructions for the smoke detector.
Programming/commissioning
Note: We recommend programming the radio modules before installing
the equipment on the ceiling.
At any one time, activate only the two radio modules that are to be programmed
and not every module simultaneously. To ensure that the other radio modules
remain deactivated, remove the three-pin terminal of the radio module (Fig. 1.3)
from the smoke detector or disconnect the battery for all other modules.
• T he radio module and the smoke detector share the same battery, which
is housed inside the smoke detector (see the instructions for the smoke
detector). Sharing the battery means that the battery life of the smoke
detector is reduced. The smoke detector indicates when it is time to change
the battery.
• C lose the battery compartment of the smoke detector. The red LED on the
smoke detector flashes briefly approximately every 45 seconds to indicate
that the battery is fitted correctly.
• C onnect the radio module to the smoke detector. To do this, remove the green
terminal from the smoke detector (Fig. 2) and plug the three-pin terminal of
the radio module (Fig. 1.3) onto the smoke detector. Carefully plug in the
terminal fully by inserting it as far as it will go until it is flush with the housing
of the smoke detector. The radio module acknowledges that the terminal
has been connected correctly with a short flash of the red LED (Fig. 1.1).
