Description
The DL-C201B is a round residential carbon monoxide alarm designed for continuous life-safety monitoring in homes, apartments, boiler rooms, hotels, and recreational vehicles. Powered by three replaceable 1.5V AA alkaline batteries, the device incorporates a high-precision electrochemical CO sensor engineered for exceptional stability and immunity against false triggers. In contrast to display-equipped variants, the DL-C201B utilizes a clean, non-LCD enclosure design to optimize circuit efficiency and maximize standby battery life. When hazardous levels of carbon monoxide are detected, the detector triggers a loud 85dB piezo horn alongside a rapid flashing red LED. It features periodic automatic self-testing, low-battery warning chirps, a combined Test/Hush button, and full compliance with the EN 50291 European safety standard.
Features
- High-Precision Electrochemical Sensor: Utilizes advanced electrochemical sensing technology to continuously detect invisible carbon monoxide gas with rapid response and stability.
- Compact Round Housing with Digital Display: Features a round form factor equipped with an LCD digital screen that displays real-time carbon monoxide levels in PPM, ambient temperature, and battery state.
- Loud Sounder and Flashing Warning LED: Emits a high-volume 85 dB alarm alongside flashing red visual indicators when dangerous carbon monoxide concentrations are detected.
- Dynamic Readout Rotation: Alternates between displaying current room temperature and 0 PPM every 22 seconds under normal ambient conditions.
- Front-Mounted Test and Silence Button: Allows easy manual testing of internal alarm circuitry and quick silencing of non-emergency alert sounds.
- Low Voltage Indication: Produces visual and acoustic low-battery warnings when supply voltage drops below 3.5V, providing 30 days of backup alert capacity.
