1. Dual Sensor Technology for Comprehensive Protection: Equipped with both a photoelectric smoke sensor and an electrochemical carbon monoxide sensor, this alarm detector provides comprehensive protection against both smoke and CO. The dual sensors ensure reliable detection of both visible smoke from smoldering fires and toxic carbon monoxide gas, offering enhanced safety in various environments.
2. Clear and Loud Alarm (≥ 80dB): The alarm volume is at least 80 decibels, ensuring that it is loud enough to be heard even in noisy environments. The high-volume alarm provides a clear and immediate warning, helping to quickly alert occupants and prevent potential hazards.
3. LCD Display for Real-Time Monitoring: The device features an LCD display screen that shows the current CO concentration levels. The LCD display allows users to monitor CO levels in real-time, providing valuable information and peace of mind. It helps in identifying and addressing potential issues before they become critical.
4. Precision Response to Different CO Levels: The alarm has different response times based on CO concentration levels: no alarms below 50 PPM, alarms within 120 minutes for levels between 70 PPM and 190 PPM, and immediate alarms above 190 PPM. This precise response mechanism ensures that the alarm only sounds when necessary, reducing false alarms and increasing reliability.
5. Suitable for Multiple Environments: Designed for use in hotels, office buildings, teaching buildings, banks, libraries, and computer rooms, this alarm detector is versatile and suitable for a wide range of settings. The device is effective in detecting both slow-burning and open flames, making it ideal for protecting various indoor spaces where smoke and CO monitoring is crucial.
