How Hardwired Smoke Alarms Work. Smoke alarms are designed to detect smoke in two ways. A photoelectric smoke alarm includes a light source, such as an LED light or laser, that sends a beam of light across the inside of the little round smoke alarm chamber from side to side. This beam forms a straight line just above the light sensor in the Carbon Monoxide Detector. Our monitored carbon monoxide detectors help prevent you and your family from being exposed to invisible, odorless, and potentially deadly carbon monoxide (CO) gas. This device comes with PowerG wireless intrusion technology, providing more secure encryption, longer range and reliability, and better battery life. The lifespan of a carbon monoxide (CO) alarm is 5-7 years, with some models lasting up to 10 years, after which time they lose their ability to smell and become inaccurate CO detectors. Due to environmental factors like temperature and humidity, Carbon Monoxide detectors’ actual life span may be shortened. Worse, Carbon Monoxide detectors do Plus, enjoy simple setup and improved wireless range via Z-Wave Plus.

Frequently Asked Questions. How does Professional Monitoring¹ work with a Smoke or CO Alarm? When your smoke alarm sounds in your home, a smoke alarm signal is sent to the monitoring center. CO moves freely through the air, so it is important that the Carbon Monoxide Alarm is not located near vents or ceiling fans, and is not blocked by furniture or curtains. Do not install carbon monoxide detectors in garages, kitchens, furnace rooms, or in any extremely dusty, dirty, humid, or greasy areas. Overview. The ADT Combination Smoke/CO Detector is an easy-to-install, battery-operated safety device that has sensors to detect smoke and carbon monoxide.
