• CO Lowest Level: 70 ppm • Self Test Period: 10 min. • Meets Underwriter’s Laboratories’ (UL) 2034 Standard, C-UL (Canada) and CE (Europe) • Loud 85-decibel horn pulsating LED warn of presence of carbon monoxide • Low-battery warning “Chirps” and LED double flashes • Energy-saving design extends battery life to more than one year under normal use • Warning “beeps” Notify you of mechanical failure • Test/Reset button in the Test mode, pressing the button makes the unit test all alarm functions. During an alarm, pressing the button temporarily quiets the alarm. • Installs quickly on wall or ceiling mount bracket, screws and 9-volt alkaline battery included. No wiring or electrical outlets needed. • Provides protection even when household electricity fails (when used as directed) Fewest false alarms Carbon monoxide (CO) facts. • The only biotechnology-based infrared-gas sensor that mimics the human response to carbon monoxide. • Detects low levels of carbon monoxide (70 parts per million) • Quick recovery. Rapidly returns to its original state when carbon monoxide is eliminated from the environment. • Every unit is 100% gas-tested to ensure accurate, timely response. • Maintenance-free. Proven circuit design, microprocessor and software. Solid-state infrared sensor uses a reservoir that never needs replacement. • Microprocessor intelligence. Self-tests every 10 minutes. Supervises sensor and alarm circuit status to ensure protection • One-year warranty and long product life
