JSN-JY-909COM Carbon Monoxide & Smoke Detector with LCD Display and Dual Sensors

JSN-JY-909COM CO & Smoke Detector - Battery-Powered Carbon Monoxide Alarm with LCD Display and Dual Sensors

The JSN-JY-909COM Composite CO Gas & Smoke Detector provides fast, accurate detection of both carbon monoxide and smoke. Equipped with advanced semiconductor and electrochemical sensors, it monitors harmful gases and airborne hazards with high precision, helping protect your home and family around the clock.

Accurate CO Monitoring with Smart Alerts
When carbon monoxide levels reach dangerous thresholds, the device triggers a loud audio alarm of ≥70 dB and flashes the indicator light. Its smart detection system follows safety response times to warn you quickly and reliably.

Clear LCD Display for Real-Time Readings
The built-in HD digital screen shows current CO concentration levels, making it easy to check indoor air safety at any time.

Quick, Wire-Free Installation
Powered by 3 × AA batteries, this alarm requires no wiring or professional installation. Mount it easily on walls or place it in key household locations.

Dual Sensing Technology for Better Protection
Using semiconductor sensors for smoke and electrochemical sensing for carbon monoxide, it ensures stable, sensitive and rapid detection of both threats.
