Battery Powered Smoke and CO Alarm with LCD Display and Voice Alert

This advanced gas alarm effectively detects both carbon monoxide and smoke. When smoke reaches a specific concentration, the detector promptly outputs an alarm signal.

Key Features:

• CO & Smoke Detection: A composite system equipped with a photoelectric smoke sensor and an electrochemical carbon monoxide sensor, ensuring reliable detection of both smoke and carbon monoxide simultaneously.
• LCD Display: Features an LCD screen that clearly shows carbon monoxide levels. An 85 dB alarm provides a loud and clear warning upon detection.
• Infrared Photoelectric Sensor: Utilizes the refraction principle of infrared light by smoke particles. The circuit comprises an infrared transmitter and receiver, discreetly placed in an optical maze to prevent interference from external stray light while allowing smoke entry.
• Unique Structural Design: Designed with advanced structural and photoelectric signal processing technology, offering dust-proof, insect-proof, and light interference-resistant features, ensuring reliable performance.
• Wide Applicability: Effectively responds to smoke from slow smoldering or open flames, making it ideal for use in hotels, office buildings, teaching facilities, banks, libraries, and computer rooms.

Important Notes:

• Avoid installation in environments that are extremely cold, hot, experience high wind speeds, or have excessive smoke and dust.
• Test the device monthly to ensure proper operation.
• To maintain optimal smoke sensitivity, clean the detector's surface with a soft brush every six months and disconnect power before cleaning.
• If both smoke and carbon monoxide are detected at alarm levels, the carbon monoxide alarm state takes precedence.
• Allow for minor size variations due to manual measurements.
• Colors shown in photos may slightly vary due to lighting and monitor settings.
