The BRK hardwire smoke alarm with photoelectric sensor is designed to reduce common "nuisance" alarms. It's an excellent choice for installations in or near kitchens, near fireplaces, or in hallways directly outside bathrooms, utility rooms, or other areas prone to steam. The alarm has a photoelectric sensor which is more effective at detecting smoldering fires which smolder for hours before bursting into flame.
