The AS01 is a stand-alone laser cavity aspirating smoke detector designed for early smoke detection in protected spaces and equipment areas. Unlike traditional point smoke detectors, AS01 actively draws air through a sampling pipe network and continuously analyzes smoke concentration inside the detector.
The detector uses laser scattering technology to identify minute smoke particles during the earliest combustion stage. When the smoke concentration exceeds preset alarm thresholds, the system can trigger different alarm levels and output signals through relay contacts or RS485 communication.
This product is suitable for applications where early warning is important, especially in areas where smoke may not quickly reach a conventional detector, or where fire risk must be identified before visible flame or heavy smoke develops.
Very Early Smoke Detection
Detects minute smoke particles at the early combustion stage, helping users identify fire risks before serious smoke spread.
Laser-Based Detection Chamber
Uses laser scattering technology to measure smoke concentration with high sensitivity and stable detection performance.
Active Air Sampling Design
Continuously draws air samples from the protected area through a pipe network for centralized smoke analysis.
Five Alarm Levels
Supports Warning, Pre-alarm, Patrol, Fire Alarm 1 and Fire Alarm 2 levels for flexible fire warning and response.
Touchscreen Real-Time Display
Provides visual smoke concentration display and easier local operation through the touchscreen interface.
Adjustable Sensitivity and Thresholds
Sensitivity and alarm thresholds can be configured according to the site environment and application requirements.
Self-Learning Function
Supports automatic environmental adaptation to help reduce unwanted alarms caused by normal environmental changes.
RS485 Communication
Built-in RS485 interface allows connection with monitoring systems for centralized management and visualization.
Multiple Relay Outputs
Provides alarm relay outputs and fault signal output for connection with fire alarm panels, extinguishing control panels, BMS or other monitoring systems.
Event Record Storage
Stores alarm and event records for operation review and maintenance analysis.
Low Maintenance Design
Includes self-cleaning function and filter maintenance guidance to support long-term system operation.

The AS01 can be integrated with a fire alarm control panel, extinguishing control panel, BMS, remote monitoring system or centralized management software through relay outputs and RS485 communication.
For extinguishing system applications, the detector should normally provide alarm signals to a releasing control panel or fire alarm control panel. The control panel should handle delay, sounder beacon activation, manual/automatic mode, emergency stop, release confirmation and other safety logic.
