USI Electric 3-in-1 Smoke & Fire + Carbon Monoxide Detector MIC1509S

Box kinda trashed. Still BRAND NEW.

The Universal Security Instruments hardwired MIC1509S 3-in-1 Smoke, Fire and Carbon Monoxide Smart Alarm will provide up to 10-years of continuous protection against 3 deadly threats within the home. Patented Universal Smoke Sensing Technology provides the benefits of both photoelectric and ionization alarms in one device to protect against fast flaming and slow smoldering fires. This alarm also features protection against the silent killer carbon monoxide, making it a 3-in-1 device. The ideal addition for new or replacement installations, this maintenance-free alarm is suitable for houses, apartments and mobile homes in every room. This alarm utilizes a sealed back-up battery (included) that will never have to be replaced throughout the life of the alarm, giving you a decade’s worth of peace of mind even in the event of a power outage. Permanent power battery backup also saves money from battery replacements (up to $38.00 over the 10-year life of the alarm), eliminates annoying low battery chirps and helps the environment by reducing environmental waste from disposed batteries. This alarm features microprocessor intelligence to completely eliminate nuisance alarms, a single silence/test button to quiet a non-hazardous alarm and an end-of-service life warning that sounds when it’s time to replace the alarm (approximately 10-years from activation).
