Smoke detector false alarm causes and solution

Post by vedard » Wed Jun 19, 2019 1:49 pm

Smoke alarm detector works for 24 hours 365 days to sense smoke before fire happens. When the alarm goes off, it makes screaming noise until the smoke disperses. So, before people see the fire or smell the smoke, the smoke alarm can make warning and make people prevent fire or extinguish fire. But cause of some reasons, the smoke alarm may cause false alarm and keeps making screaming noise. Then, people may remove the smoke alarm directly. Thus, when real fire happens, no alarm and prevention, people will get into disaster.
So, we list the smoke detector false alarm causes and solution to help solve problems.
1. False alarm caused by cooking smoke.
Ion smoke detector is sensitive to cooking smoke particles. So, should remove the ion smoke detector far from cooking place (and upper of air flow). Or, replace the ion smoke detector with photoelectric smoke detector.
2. False alarm caused by Steam or moisture.
If too much steam is gathered on the smoke sensor circuit board, it will make alarm. So, avoid to install smoke detector in bathroom. Replace it with heat detector. If the smoke alarm in bath room can work well before but makes false alarm recently, then it may be out of usage ages. Should replace it with a new one.
3. False alarm caused by cigarette.
Generally smoke alarm will not be triggered by cigarette smoke. If many people smoking in a room and makes large amount of smoke, it may cause smoke alarm. Otherwise, the smoke detector sensitivity is too low and it may be out of usage age. Need to replace a new one.
4. Low power alarm
If the smoke detector is with low battery power, it will make alert of short Di Di sound. So, should replace a new battery.
5. If the smoke detector keeps triggering alarm and no other causes, then too much dust is gathered inside the smoke detector. So, uninstall the smoke detector and clean it with vacuum cleaner. Or replace it with a new one.
