Description
The DL-C501 is an advanced residential carbon monoxide alarm engineered for long-term life-safety monitoring in homes, apartments, boiler rooms, hotels, and recreational vehicles. Powered by three replaceable 1.5V AA alkaline batteries, the device utilizes a high-precision electrochemical CO sensor with an operational service life of up to 10 years. It features an integrated backlit digital LCD display that alternates between real-time carbon monoxide concentrations (25–600 PPM) and ambient room temperature (°C), along with continuous battery level status. Upon detecting dangerous CO gas accumulation, the detector activates a loud 85dB piezo horn alongside visual red LED indicators. The unit incorporates automatic sensor self-diagnostics every two minutes, low-battery warning alerts, end-of-life replacement notifications, and full certification under the EN 50291 standard.
Features
- Long-Life Electrochemical Sensor: Built with an advanced electrochemical sensor that provides precise, continuous monitoring for up to 10 years.
- Multi-Function Digital LCD Display: Shows real-time carbon monoxide levels in PPM, ambient temperature, and a 4-level battery status indicator.
- High-Decibel Audible and Visual Alarm: Triggers a loud 85 dB horn along with a flashing LED indicator upon detecting hazardous carbon monoxide gas.
- Alternating Display Readout: Alternates between displaying current room temperature and 0 PPM every 22 seconds under normal ambient conditions.
- Automatic Self-Test Function: Performs periodic internal diagnostic checks every two minutes to ensure full system health and sensor accuracy.
- Integrated Test and Silence Control: Features an easy-access front button for routine manual functional checks and temporary silencing of non-emergency alerts.
- Low Battery and End-of-Life Warning: Emits audible chirps and visual prompts when batteries drop below 3.5V or when the sensor approaches the end of its service life.
