In a typical house fire burning material smoulders and smokes for a long time (possibly a few hours) before flaring into flames. Experts say photoelectric smoke detectors generally won’t cause as many false alarms, but for the ultimate in safety, they recommend opting for a smoke detector with both types of sensors. Photoelectric smoke alarms are usually much faster at detecting smoke from smouldering synthetic material than ionisation alarms. These contain a very small amount of radioactive material, which reacts to particles emitted in a fire and sets off the alarm. There are generally two options, both of which work, but one of option is definitely a safer and more reliable choice. While they all do the same job, they go about it differently. The air … A combination of the two types of alarm (dual sensor smoke alarm) is recommended for maximum protection from both fast flaming and slow smouldering fires.
