These alarms are best for quick fires that produce little smoke, but burn very hot and quickly. The most common household fires are the slow smoldering types that emit a lot of smoke before they erupt into flame. Often ionisation alarms are slow at detecting these types of fires. They are also likely to be activated from steam or cooking fumes, so are generally not used in kitchens, laundries and bathrooms
