USI Sensing Plus Smoke and Fire Detector

No, this specific model is designed exclusively for smoke and fire detection. It does not monitor for carbon monoxide.

It means you never have to change a battery for the entire life of the unit. The battery is permanently sealed inside, which eliminates those annoying low-battery chirps in the middle of the night and saves you the hassle of annual replacements.

This unit uses microprocessor intelligence specifically designed to distinguish between dangerous smoke and common cooking nuisances. While no smoke alarm is completely immune to false alarms, this technology significantly reduces the frequency of accidental triggers.

Yes, this unit is hardwired and interconnectable with up to 24 other compatible devices. When one alarm detects smoke, all connected units will sound, providing an extra layer of safety throughout your home.

Dual sensor technology combines photoelectric and ionization detection to identify both fast-flaming fires and slow-smoldering fires. This provides more comprehensive protection than a single-sensor alarm, which might be better at detecting one type of fire but slower to react to the other.

The device features an end-of-service life warning that will alert you when it is time to replace the unit. Because the sensor and battery are designed to last for 10 years, you should plan to replace the entire device a decade after installation.
