HY-ASD420B

Aspirating Smoke Detector

> Precise detection: immune to moisture or dirt particles thanks to infrared and blue light dual-wave length laser particle identification technology
> 24/7 self-learning: environment dynamic self-learning algorithm enables the environment adaptation in the monitored region
> Intelligent monitoring: advanced MEMS airflow sensing technology is capable of monitoring pipe fault and blockage
> Dual detection: verifying smoke and gas (supports standard Figaro CO sensor and other customized smoke)
> Test function: one-click button to test key components
> User-friendly interaction: a 7-inch color touch panel for displaying smoke concentration. Configuring parameters directly from the user interface without physical access to the device
> Detection chamber self-cleaning: continuous airflow allows the self-cleaning in laser detection chamber
> Large monitoring area: Max. length of a sampling pipe is 120, the maximum number of sampling holes is 30, and the monitoring area surpasses 2000 ㎡
> Easy maintenance: intelligently monitoring sensor life, conveniently replacing the old sensor
> United calibration: based on smoke concentration detection, the smoke chamber is 100% calibrated
> Smart IoT: connect to the IoT platform via the Ethernet port, RS-485, 4G, and CAT1
> Diversified operation modes: supports the independent operation and connection to remote CRT software or IoT platform through RS-485
> Customized events: support customized events covering alarm and fault. Conveniently integrated into the third-party devices
> Records query: supports a total of 200,000 records
> Remote control: remotely reset through the switch interface or IoT platform to quickly address the alarm
