The Failure Rate Of Ionisation Fire Smoke Alarms
Hero Fire Protection recommends using a photoelectric smoke alarm such as the OmniShield state-of-the-art smoke sensor because it will go off when black smoke is detected.

The most common smoke detectors have an alarming rate of failure. Some can take as much as 30 minutes to activate. Most smoke alarms found in the market are ionization smoke alarms. This type of alarm uses a small amount of radioactive material to ionize air in an internal sensing chamber. When smoke enters the chamber, the conductivity of the chamber air will decrease to a predetermined level, the alarm is set off. However, the ions can still flow through despite the particles in a real fire, such as black smoke, entering the chamber.
