Battery check - Changing the battery
The smoke detector is supplied with voltage by a 9 V block battery. The
battery test automatically checks the supply voltage in regular intervals. If the
battery voltage drops below a defined point, the smoke detector signals for
30 days that the battery has to be replaced. The smoke detector is completely
functional during this period.
Proceed as follows to replace the battery:
1. Remove the smoke detector from the base (turn counter-clockwise).
2. Remove the old battery from the compartment and disconnect the
connec-tor from the battery connection.
3. Connect the new 9 V block battery to the battery connection and insert
the battery into the battery compartment.
4. Insert the smoke detector back into the base and latch it in by turning it
slightly clockwise.
