1. Vacuum all smoke detectors 
– This should be done at least annually. If you live in places with a lot of pollen or particles in the air ( in the city), recommend at least twice a year: After the pollen season and together with the battery change. If you have access to compressed air, this is much more efficient. 

2. False alarm – witch sensor triggers the alarm? (RF only)
– If you have a Cavius HUB it is easy to locate which sensor triggers the alarm. Or, try to set all alarms to different channels, IE program each detector to it-selves . Then you will have “standalone” smoke detectors and it is easy to find the location of the nuisance alarm.

3. Change location with another alarm
– If you know which sensor are causing the nuisance alarm, change location with another alarm that does not give alarms. Give a number to the smoke alarm that causes nuisance alarm and create a log .In this way, one can determine whether it is the alarm or the location that is the problem. Here there may be other things that affect the alarm. Also the nuisance alarm sensor should be moved to another location.
a. Does the problem continue at a new location, i.e. it follows the alarm, contact the place you purchased the alarm.
b. If the problem continues at the same location with another alarm, there is something that affects it. Maybe it should be moved.

4. Error source: Electromagnetic field, EMC Electromagnetic fields can interfere with the electronics of the smoke detector. These fields are often formed around fluorescent lamps, “down lights”, transformers for light, fuse boxes, fan motors etc. – Always install the smoke detector at least 100 cm from this type of equipment. NOTE: EMC does not drain the battery 

5. Error source: Radio noise Other components that contain radio transmitters can cause interference and affect battery life. As such signals are constantly changing, customers may experience problems in installations that are mounted and have worked fine
– Try to locate what has changed, has the customer bought new equipment, development of emergency network / 4G etc?
NOTE: Radio noise also drains the batteries on smoke detectors, as the detector constantly analyzes the signal.   

6. Error source: Steam and damp air Steam from the bathroom, washer / dryer or other sources that emit high humidity can cause the smoke alarm to sound
– Pull the notifier slightly away from the door to the washroom / bathroom. You can also make sure to ventilate well and avoid releasing steam directly into the room where the smoke detector is. If you have an ionic alert placed where water vapor can occur, you may want to switch it to optical. Optical smoke detectors are more tolerant than ionic warnings to roast and water vapor, as well as strong traits. 

7. Error source: Dust and dirt Since air must pass freely through the detection chamber, the smoke detectors will always attract a lot of dust and pollen particles. By entering dust and other particles into the detection chamber, this can lead to false alarms. The alert may also become more sensitive due to this and will give more false alarms, as the smudge causes it to be smaller before it goes into alarm. Dirt will also occur over time as the smoke detector gets older, which causes it to give more alarms
– Vacuum the smoke detectors regularly, but be careful not to damage the electronics. If you clean up a room and this results in grinding or sanding, you should install the warning device while the work is in progress or cover it. The bathing caps lying around in hotels are well suited for this. If the smoke detector approaches 10 years and gives many alarms, it is time to replace it.

8. Error source: Draft In heavy drafts, the wind can drag dust particles with which the smoke detector looks like smoke –  Avoid installing the smoke detector where it is a draft, or make sure that the breakthrough does not occur around the detector. 

9. Error source: Temperature variation When you open the door on cold winter days, rapid temperature changes can occur. Condensation can then form which can cause a false alarm. Can also occur during venting and if the alert is close to open valves on cold days
– Avoid mounting the smoke detector in rooms with large / fast temperature fluctuations. 

10. Fault source: Gases from paint, varnish and strong cleaning agents Gases from paint, varnish and other chemical agents may contain substances on which the smoke detector reacts
– Remove or cover the smoke alarm when refurbishing the room. NB! Remember the fire hazard when using chemicals. All cloths and rags MUST be wetted and thrown into tight containers stored outdoors or burned under controlled conditions.
