Description

The Kidde 900-CUAR is a hardwired smoke and carbon monoxide detector, with interconnectable AA Battery Backup, which helps protect you and your family from two hazards fire and dangerous carbon monoxide (CO) in one unit. This smoke and carbon monoxide detector combo features self-testing components that are always checking to make sure the alarm is on and working. This is a photoelectric smoke alarm, meaning it may provide better detection of larger, visible fire particles (the kinds associated with slow smoldering fires). Fire safety experts advise using both photoelectric smoke detectors, like this one, and ionization smoke detectors which may be better at detecting small, less-visible fire particles (those that emit from fast-flaming fires). Install both throughout your home for optimal smoke and fire detection.
