2 In 1 Smoke And Carbon Monoxide Detector Battery Powered With Sound Warning Number Display

This 2-in-1 Smoke and Carbon Monoxide Detector combines advanced sensing technologies to provide reliable protection against two major household hazards. Equipped with an electrochemical carbon monoxide sensor, it offers superior accuracy, lower power consumption, and an extended service life compared to conal electrochemical techniques. The infrared photoelectric smoke sensor ensures precise smoke detection while minimizing false alarms, making it ideal for indoor environments such as villas, factories, shopping malls, warehouses, and office buildings.

Features:
2-in-1 Protection: Detects both smoke and carbon monoxide with high-precision sensors for comprehensive monitoring.
Low Power Consumption: Powered by 3*1.5V AA batteries (not included), it enters normal operation 2 minutes after battery installation with a power-saving design that displays nothing during standby, ensuring ultra-long standby time.
Loud Alarm: Emits a sound of ≥85dB when the test button is pressed, loud ugh to alert you to dangers whether you’re asleep in the bedroom or downstairs.
Easy Installation: Simply drill two marked holes, tap in the plastic grommets, and mount the bracket to the ceiling using the supplied screws.
Flexible Protection Area: When installed in spaces 6-12 meters high, the protection area is generally 80 square meters; for spaces below 6 meters high, it covers 60 square meters.

Installation Steps:
1. Insert batteries into the compartment according to the indicated polarity.
2. Choose the optimal location, typically the center of the ceiling in the detection space (recommended for bedrooms, hallways, basements, cars, or any area where people stay for extended periods).
3. Secure the detector base to the selected position using the mounting screws.

Specifications:
Item Size: 4.7 × 4.7 × 1.8 inches
Item Weight: 6.4 ounces

Package Includes:
1 x Smoke and Carbon Monoxide Detector (Battery not included)
1 x Instructions
2 x Mounting Screws
2 x Rubber Stoppers

Please Notes:
- Install the detector 0.3~1m below the ceiling, as carbon monoxide and smoke are lighter than air and accumulate near the ceiling.
- Avoid spraying air fresheners, hair sprays, paints, or other aerosols around the detector to prevent interference.
- Do not wipe the detector with detergent, as chemicals may permanently damage the sensor.
- Do not install in locations with normal smoke accumulation, relative humidity >95%, heavy water/oil mist pollution, or high wind speeds (>5 m/s).
- This detector helps reduce accidents, but maintaining vigilance and strengthening awareness is still essential.
