Product description
The retrofittable radio module sends and receives alarm signals in conjunction
with other radio-networking FlammEx products if they also have an FMF 3545.
As soon as an alarm via the network terminal emits, 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 When the alarm is no longer active at the
original triggering device, 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 host device, as described in its instructions. 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 host device 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 host device.
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 host device or disconnect the battery for all other modules.
• The radio module and the host device share the same battery. Sharing the
battery means that the battery life is reduced.
• Close the battery compartment of the host device. The red LED on the host
device flashes briefly approximately every 45 seconds to indicate that the
battery is fitted correctly.
• Connect the radio module to the host device. To do this, plug the three-
pin terminal of the radio module (Fig. 1.3) onto the host device. (For smoke
detectors, you must first disconnect the green terminal from 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 host device. The radio module acknowledges
that the terminal has been connected correctly with a short flash of the red
LED (Fig. 1.1). The host device may emit a short beeping sound when the
terminal is being plugged in. If the terminal is attached incorrectly, smoke
detectors triggers an alarm immediately. Do not close the lid yet, as the radio
module must be programmed first.
