Each wireless module must be taught into a wireless receiver if the receiver is to react to the module. For this, you will require a compatible smoke alarm device that allows wireless module installation.
The smoke alarms can emit different operating or alarm signals. Please refer to the operating instructions to find out what the signal indicates. Examples of operating signals:
a general fault (8 short signal tones in 60s cycle),
a weak battery (2 short signal tones in 60s cycle) or
an EMC fault (short signal tone in 1s cycle).
The operating instructions can be found in the online catalogue or at the following URL:
At temperatures below -20°C, the rain monitor output is activated; above this temperature, snow and rain detection takes place as usual.
The assignments for smoke alarm devices with wireless module remain the same after changing the battery.
In most cases, the unit is past its replacement date; if it is more than 10 years old, it needs to be replaced. The first step is to check the replacement date on the back of the smoke alarm.
However, there are several other factors that can reduce the battery life. A full summary can be found in the operating instructions. Other factors for a weak battery are:
The frequency with which the smoke alarm is triggered: frequent false alarms or test alarms lead to an earlier discharge.
The location of the installation, in particular compliance with the installation instructions according to the operating manual: Excessive temperature fluctuations, e.g. due to environmental influences, lead to reduced battery life.
Networking of smoke alarms via the networking terminal: if several smoke alarms are connected to each other, the battery life can be reduced.
The additional use of modules: The use of additional functions (e.g. KNX signal transmitter) can also lead to a reduction in battery life.

If none of these factors apply to you, contact your local electrician to have the device checked.
