2-in-1 smoke and carbon monoxide detector with digital display and audible and visual alarms

Smoke and Carbon Monoxide Detectors: Beeps when both gases are detected.

These smoke detectors use high-precision electrochemical sensors to alert you to the dangers of carbon monoxide, and photoelectric sensors to detect smoke while minimizing false alarms. Protect your safety.

Smoke detector powered by 3 AA batteries (batteries not included). Easy to install. When the battery is running low, it emits a continuous beep every 30 seconds to remind you to replace the battery. A flashing low-battery indicator light shows that it is working.

Suitable for any location where smoke and carbon monoxide are generated, such as kitchens, bedrooms, hotels, apartments, and markets. Also suitable for barbecues, charcoal heaters, garages, etc.
