【ZX-CO20】
Wireless CO Detector

This CO20 detector adopts high-precision sensing module to rapidly capture carbon monoxide from gas leaks, charcoal burning and vehicle exhaust. It triggers alarm within 30 seconds at 100PPM CO concentration to avoid delayed warning risks. The sensor serves a 5-year service life, with yellow indicator light reminding users to replace the sensor timely. Suitable for kitchens, bathrooms, living rooms and vehicle parking areas to eliminate hidden CO poisoning hazards in daily life.

Features a clear LCD screen that real-time displays accurate CO concentration value in PPM for intuitive data reading. Four colored indicator lights distinguish different working states: green for normal monitoring, yellow for sensor expiration or device fault, red for gas alarm. Users can instantly judge equipment status without complex operations, realizing visible safety monitoring all day long.

It outputs standard 85dB alarm volume, loud enough to wake sleeping people while avoiding excessive harsh noise damaging hearing. When CO exceeds safety threshold, the buzzer sounds continuously with red light flashing synchronously to deliver dual audio-visual reminders. Unlike over-loud industrial detectors, its volume design balances warning efficiency and daily comfort for long-term indoor use.

The device conducts automatic self-check every 60 seconds with flashing green light to prove normal operation. A dedicated TEST/SILENCE button supports manual function inspection and temporary alarm mute. It automatically identifies device malfunctions, low battery and expired sensors, triggering corresponding light prompts to remind maintenance, greatly reducing hidden safety risks caused by detector failure.

Operated by 3 AA batteries without wired power supply, supporting quick wall mounting with matched 3M adhesive, no drilling required. It adapts to working temperature of 0℃-55℃ and humidity below 95%RH, stable for long-term indoor use. The flame-retardant shell improves fire resistance, ideal for gas kitchens, shower rooms, hot pot restaurants and indoor parking spaces to guard family safety round the clock.
