The FireAngel SB1 optical smoke alarm is best at detecting slow smouldering fires and is less prone to nuisance alarms. It features a large test and silence button and has an audible low battery warning when the batteries need replacing. The alarm is powered by a 9V battery which is supplied with the alarm and has a 3 year warranty.
In order to achieve the earliest fire warning, we recommend that a smoke alarm is fitted in all rooms where the temperature is normally between 4°C (40°F) and 38°C (100°F).
