It actively analyzes particulate matter concentration, characteristic gas concentration (H₂, CO, CH₄, VOC), and ambient temperature/humidity in sampled air and triggers an alarm when preset thresholds are exceeded.
Key Features
This system can professionally and reliably solve early fire hazard detection challenges in multiple scenarios and has the following advantages:
Sensitive: TheAT-AS04 detector is highly sensitive, capable of detecting small particles, characteristic gases, and temperature in the early stages of combustion, providing early warning for fire hazards.
Accurate, No False Alarms: The AT-AS04 detector uses multi-parameter analysis principles, making early fire warnings extremely accurate.
Locates Small Spaces: Protects a space of 2 cubic meters.
Multi-Parameter Visualization: Real-time display of particulate matter concentration, characteristic gas concentration, and target air temperature/humidity.
Easy Operation: Can be operated and set via smart terminal display, eliminating the need for button operation, providing great convenience for users.
Multi-Level Alarm Function: Supports multi-level alarms: Alert, Pre-Alarm, Patrol Alarm, Fire Alarm 1, Fire Alarm 2, configurable by the user.
Self-Learning Function: Periodically collects and automatically analyzes ambient conditions, automatically adjusting appropriate parameters for customer convenience.
Historical Alarm Query Function: Can save up to 30,000 historical alarm records.
Event Logging Function: Can save on-site operation records for background query.
The detector is suitable for installation in:
Internal compartments of communication equipment cabinets
Power system equipment and power distribution cabinets
Internet data-center racks and cabinets
Box-type substations
Other confined electrical enclosures that require early fire-warning protection
