ASD-VT2 serise
Inspiratory smoke detector is a new generation of laser detection technology, which can provide early alarm before the fire is brewing. It is not affected by low temperature, and has excellent alarm performance. Based on the application of nano detection technology, VT series detectors reduce false alarms and improve the accuracy and detection performance.
Micro-nano Detection technology
The air passes through the ultrasonic airway and reduces the cross section step by step, which makes the air accelerate to move and then intercepts the flow through the isolation and continuous curve, effectively restraining the interference of larger particles, ensuring that only less than 2 μ m of air soluble colloidal particles enter the laser cavity, improving the discrimination ability of particles and effectively reducing false alarms.
LTR-Low temperature resistant technology
The technology of "paraboloid focusing" with high sensitive lens is used to gather multi angle light points in the center, and the lens is treated with nano coating technology to prevent the influence of condensation caused by rapid temperature difference and break through the limitation of low temperature environment. It makes the low temperature limit reach - 60 ℃, ensures its reliable sensitivity and the system is more stable, and upgrades the laser application technology.
ASD-MMS networking
MMS system is based on ASD family detector connected by LAN or Ethernet as standard configuration. Through network, V-TEC system software asdnet can realize central control and monitoring. Powerful asdnet can realize online concentration, airflow, partition, event information and fault detection, fire source location and voice broadcast management functions.
