Review title: Solid with Easy Installation
Product review: I replaced three smoke detectors with these units. The added Carbon Monoxide detection is a great feature and is coupled with the interconnectable talking between the units. These units have a nice piercing alarm accompanied with voice alarms. The hard-wiring for these units is a basic white, black, red model that anyone with simple wiring knowledge can achieve without bothering with the adapters that are sold separately.
