In case of improper function of the smoke alarm detector, please contact the manufacturer!

≥ 85dB (A) within 3m
6. Replacing batteries
1. The smoke alarm detector makes a recurring beep sound in 30 to 40 second intervals for 30
days. With this it points out that the battery must be changed. Additionally the LED flashes.
The smoke alarm detector is still fully functional at this time. However, it is recommended to
replace the battery, as soon as the smoke alarm detector is warning about the empty state of
the battery! Please always replace the battery with an identical battery type, which is having
the same technical specifications as the used battery (lithium battery: ER9V). Never use
batteries or power supplies for operation of the smoke alarm detector. These can cause false
alarms or lead to a complete failure of this product.
2. To release the mounting base from the smoke alarm detector you have to turn it
counterclockwise (
see Figure 6
). Then replace the battery with a new battery. Make sure that
it is the identically constructed battery with DC 9V (Lithium battery: ER9V)!
