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.
If you do not have an electrical specialist available to carry out the inspection, please contact us. You can find the contact form here: https://partner.gira.com/en/kontakt/international.html
If the smoke alarm device has triggered an alarm, this can be acknowledged by briefly pressing the function button. The alarm trigger must then immediately be found and rectified, otherwise another alarm will be triggered after 15 min.
A local smoke alarm is indicated by a loud intermittent tone and the flashing red light ring. The alarm device that triggers the alarm must always be found and acknowledged.
Smoke alarm devices used individually:
Identify the smoke alarm device that triggered the alarm. The smoke alarm device that detected the fire will have a red flashing LED as well as emitting an audible signal. Remove the battery from the smoke alarm device. This mutes the smoke alarm device.
Networked smoke alarm devices (wired or via wireless module):
Identify the smoke alarm device that triggered the alarm. The smoke alarm device that detected the fire will have a red flashing LED as well as emitting an audible signal. Remove the battery from this smoke alarm device. This mutes both this device and all the smoke alarm devices networked with it.
No, the light ring only flashes if there is an alarm or a fault.
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).
