When it comes to your family's safety, there's no room for second guessing. The USI Electric 2-in-1 Photoelectric Smoke and Fire + Carbon Monoxide Alarm with 10 Year Sealed Battery uses Smart Alarm Technology so you and your family will be safe. The Photoelectric Technology is generally effective at detecting slow smoldering fires and Smart Alarm Technology virtually eliminates nuisance alarms, so you can trust what you hear. Drift compensation auto-adjusts alarm sensitivity if the chamber becomes dusty or dirty over time, while automatic temperature and humidity compensation adjusts to variations in environmental conditions. A distinctive audible alarm signals the presence of carbon monoxide or smoke alarm hazards, with separate LED visual indicators to distinguish between the two dangers. This reliable alarm can be interconnected with up to 24 compatible USI Electric alarms and devices and Quick Find alarm origination easily locates the first alarm to sound in an interconnected system.
