Hardwired with Battery Backup

Hardwired combination smoke alarm and carbon monoxide (CO) alarms connect directly to a building's electrical system and typically include Lithium-ion battery backups in the event of power outages. This dual-power approach enhances reliability and ensures continuous detection for fire or CO gas. The importance of these combination alarms lies in their ability to detect both smoke from potential fires and the presence of carbon monoxide—a colorless, odorless gas that can be lethal if undetected. Early detection of these dangers is crucial, as it provides occupants with the necessary time to evacuate and seek assistance.

Modern combination alarms often feature advanced sensors, such as photoelectric sensors for smoke detection and electrochemical sensors for CO detection, enhancing their accuracy and reducing false alarms. Additionally, hardwired alarms can be interconnected, meaning when one alarm detects smoke, all alarms in the network sound simultaneously throughout the building or house.

While offering heightened safety features, hardwired systems require professional installation and may involve higher initial costs. Choosing between battery-operated and hardwired smoke alarms depends on factors such as building infrastructure, budget, and a facilities specific safety requirements.
