Fire Alarms

A fire alarm detects the smoke generated by a fire and warns the resident of danger with a siren. Smoke is more dangerous than fire due to the fact it can fill the entire residence in mere moments and potentially cause grave danger to e.g. a sleeping person.  

When used, placed, and maintained correctly, the fire alarm can save lives.

Maintenance instructions:

  • The fire alarm's functionality must be tested once per month, by pressing the test button on the alarm device.
  • Make sure to also test the fire alarm's functionality at your holiday home, or if you have spent a long time away from home.
  • The batteries on the fire alarm must be replaced once per year.
  • If the fire alarm is beeping occasionally, the batteries must be replaced.
  • If the fire alarm does not function despite a change of batteries, it must be replaced with a new alarm device.
  • If the fire alarm is dusty, the outside should be vacuumed. If dust has built up inside the alarm device, replacing the device is recommended.

The law mandates a fire alarm to be installed every 60 m², on every floor of every residence. Holiday homes such as summer cottages must also be fitted with their own fire alarms.

The fire alarm must be attached to the ceiling, more than 50 centimetres from the wall, between the bedrooms and other areas. If there are multiple floors in the residence, the upper floors require the alarm to be attached to the ceiling above the stairs.

It is advisable to install fire alarms in each bedroom and the hall. For large residences, interconnected alarms are recommended because when one alarm goes off, it also causes all other connected alarms to go off at the same time.
