Domestic smoke alarms (Germany)
A list of checks and obligations with their cadence, ready to add to your agenda.
For anyone who owns, lives in or lets a home in Germany. Covers the two dates that actually matter — the function check at least once a year and the replacement of the unit no later than ten years and six months after it was put into service — together with a check on where alarms are required, the split of responsibility between owner and tenant, and the record of the check, which matters most to landlords. Commercial fire detection systems and carbon monoxide alarms are out of scope.

Clarify who installs and who maintains
Installation and day-to-day upkeep do not always sit with the same person: almost everywhere the owner installs, but several states assign upkeep to the tenant, and others leave it with the owner, who may then delegate it by contract. Writing down in the tenancy agreement who does what avoids the argument after an incident, when whoever was obliged will answer. If upkeep is contracted to an outside company, say so too, along with how the tenant grants access.

Replace the alarm after 10 years and 6 months
The deadline runs from the moment the alarm was put into service, not from the purchase date and not from the date printed on the box: ten years plus six months, and then the unit is replaced, not repaired. The optical chamber ages and loses sensitivity even if the alarm never sounded and the battery still holds. Who replaces it depends on the state building code, as with the annual check. Writing the in-service date on the unit at the time of fitting is what makes this deadline manageable ten years later.

Check where smoke alarms are required
The duty to install exists in all sixteen states, but it is written in each state building code and the wording differs: in general alarms are needed in bedrooms, children rooms and the hallways that serve as escape routes, and some states ask for more. This card does not list the rooms state by state: read the building code of your own state. Installation is normally the owner duty, even for a let flat; the review matters after a change of use of the rooms or a refurbishment.

Test each smoke alarm once a year
At least once a year, with a tolerance of plus or minus three months, every alarm must be tested: test button, smoke inlet free of dust and cobwebs, no new object or piece of furniture within half a metre. Who has to do it depends on the state building code — in many states the tenant keeps it operational, in others it stays with the owner — and in both cases a specialist company may be engaged. The check helps meet the duty to keep the alarm ready for use: it does not replace it and it certifies nothing.

Document the annual check
Someone checking their own home owes nobody a record, but a sheet with date, rooms checked and result costs nothing and helps memory. For landlords it is a different matter: after a fire the insurer question and the court question are the same — who checked, and when — and without a record the answer is one word against another. If a company does the check, its report listing the units and serial numbers is enough on its own.

Never ignore a fault or low-battery signal
A single chirp every thirty or sixty seconds is not a fault of the alarm: it is how it reports a nearly flat battery or a malfunction. On models with a replaceable cell you change the battery; on those with a sealed ten-year cell that signal means the unit has reached end of life and must be replaced. Taking it off the ceiling to silence it is the most common reaction and the fastest way to end up unprotected: if the signal comes at night, change the battery straight away and refit the alarm in the morning.
