Combination Alarm
Engineered to meet the latest ETL standards (UL217 10th Ed. and UL2034 5th Ed.), this alarm utilizes both photoelectric and electrochemical sensors for highly accurate detection. It features an intelligent bilingual voice warning system (English/French) that clearly announces the specific threat, such as "Fire!" or "Warning, Carbon Monoxide." With multiple smart silence functions—including an 8-minute smoke silence, 5-minute CO silence, and a 10-hour Do Not Disturb mode for low battery warnings—it ensures your peace of mind while minimizing nuisance alarms.
