Alarming question

Smoke alarm.
Smoke alarm.

Could someone please explain the different types of smoke that activates the new fire alarms fitted by the Fire Department.

If I burn anything while cooking and there is smoke, the alarm doesn’t go off (my old alarm did).

When I rang the Fire Department I was told there are different types of smoke and there is only one that activates the alarm.

My friend has had a similar experience!
