Hardwired Combination Photoelectric Smoke and Carbon Monoxide Alarm with Battery Backup

The Hardwired Combination Smoke and Carbon Monoxide Alarm with Battery Backup delivers both smoke and carbon monoxide detection in a single unit. Equipped with a photoelectric smoke sensor and an electrochemical CO sensor, it accurately detects smoke produced by smoldering fires and carbon monoxide leaks from multiple sources. If a threat is detected, the alarm emits a spread spectrum horn tone that is designed to be heard by people with age-related hearing loss.
