13. Replacing the batteries
a) General information
Stop a moment! Please read the following pages before you replace the
batteries.
When high-quality alkaline batteries are used, the batteries in the smoke detector can last for
longer than 3 years (if no alarm is set off).
When using conventional devices you normally only notice that their batteries are flat when the
devices no longer work (in the case of a radio or a remote control, for example).
When using an important device such as a smoke detector, however, this could
have fatal consequences!
For this reason, the smoke detector emits a short alarm signal (approx. every 48 seconds)
when the capacity of the battery reaches a specific level. In addition, the red LED blinks three
times every 48 seconds.
The smoke detector’s battery level is evaluated, displayed and stored as a fault
by the ‘HMS 100 Z’.
For this reason, a particular procedure must be followed when replacing the
batteries.
To proceed, please follow the instructions provided on the following pages.
