Why smoke alarm beeping when there is no smoke?

To know why the smoke alarm beeps, let's get to know when it alarms. The smoke alarm usually alarms for these 3 situations: when there is a smoke, and it alarms when the smoke level reaches the value; secondly it might be a fault alarm when there is a bug or some dust wents in; thirdly it will also alarms when it's low battery warning. So how can we get to know why it alarms? You can also judge by the LED indicator that tells you the real reason. When the Green indicator flashes once perminute it means it's standby. When the Red indicator flashes once per second it means it has detected the smoke and alarming. When the Red indicator flashes once per minute means the smoke alarm is in fault. When the Red indicator flashesonce per minute that means the smoke alarm is already Low battery. You need to change it.

What is the type of smoke alarm, photoelectric or ionisation?

The smoke alarm uses photoelectric smoke sensor for responding quicker to smouldering fires and the dense smoke given off by foam filled furnishings or over heated PVC.

Should I clean my smoke alarm?

We advise cleaning your smoke alarms at least once every three months. To get rid of any accumulated dust or insects, run your vacuum's brush attachment over the grates on the sides of the alarms. Please avoid using any cleaning agents to clean the alarm and avoid painting the units.To guarantee the smoke alarm can protect you and your house, test it regularly and replace it after 10 years.
