The 4-in-1 Smart Alarm uses patented IoPhic Universal Smoke Sensing Technology and protects against 4 deadly household threats: smoke, fire, carbon monoxide and natural gas (methane). NEW Smart Alarm technology makes conventional alarms obsolete. IoPhic alarms respond 87 percent faster to slow smoldering fires and respond quickest to fast flaming fires. The only alarm to virtually eliminate nuisance alarms from sources like every day cooking smoke and steamy showers. The first new smoke alarm technology to launch in more than 30 years and first ever 4-in-1 Smart Alarm. IoPhic is ideal for installation in every room—combining the benefits of both photoelectric and ionization technology in one alarm. Smart Alarm Technology® uses microprocessor intelligence to protect against both fast flaming and slow smoldering fires with a single sensor. IoPhic alarms respond up to 87% faster* than the maximum allowable alarm limit to slow smoldering fires and responds quickest to fast flaming fires.
