Why Early Warning matters
Most high-loss incidents don’t start with open flames. They begin with early-stage combustion, overheating, and invisible smoke particles inside equipment and cabinets—long before conventional detection reacts.
ANWETECH’s early warning product line (AS01–AS04) is built to detect risk earlier, reduce downtime, and enable faster response across multiple facility types.
Product Line Positioning (How to choose)
AT-AS01 – Aspirating Smoke Detector (General-purpose ASD)
Early-warning air-sampling smoke detection for mission-critical spaces, with flexible pipe network and continuous airflow monitoring.
EN 54-20 compliant, optional 2-zone / 4-zone versions; five alarm levels (Warning / Pre-alarm / Patrol / Fire 1 / Fire 2); RS485 + multiple relay outputs; up to 30,000 event/alarm records.
AT-AS02 – High-Sensitivity ASD (Data Centers & Cabinets)
Air-sampling technology for very-early smoke detection; EN 54-20 compliant with optional 1-zone / 2-zone / 4-zone versions.
High sensitivity, five alarm levels, RS485 + multiple relay outputs, 30,000 records (alarm/event)
AT-AS03 – Electrical Cabinet Early-Warning Detector
Designed for early fire hazard detection using multi-parameter analysis (particles + characteristic gases + temperature/humidity display), optimized for small/localized spaces.
AT-AS04 Electrical Micro-Environment Fire-Warning Detector (Confined Electrical Spaces)
Early fire-warning device for confined electrical spaces; analyzes particulate matter + characteristic gases (H₂ / CO / CH₄ / VOC) + temperature/humidity and alarms on preset thresholds.
Multi-level alarms + self-learning + history/event logging (up to 30,000).
Practical project integration commonly uses 24VDC supply, RS485 and relay outputs (refer to AT-AS04 manual).
2Facilities Covered (Complete List)
A) Data & Telecom Critical Areas
Data Centers, Server Rooms, Network/Telecom Rooms, NOC/Control Rooms, MDF/IDF rooms

E) High-Value Asset Protection
Libraries, archives, museums and other high-value asset rooms
Recommended: Very-early warning ASD (AS01/AS02) to detect minute smoke particles at the earliest combustion stage
Standard Solution Architecture (One logic for all facilities)
Layer 1 — Early Warning Detection (Core)
Room/area-level: aspirating smoke detection (AS01 / AS02) with sampling pipe networks and continuous airflow monitoring.
Equipment/cabinet-level: micro-environment early warning (AS03 / AS04) close to the source of risk in confined electrical spaces
Layer 2 — Alarm Integration (Project-dependent)
- Multi-level alarms enable “early action” (inspection/maintenance) before escalation.
- RS485 + relay outputs support linkage to fire alarm panels, monitoring platforms, or site logic controls.
Layer 3 — Expansion for Suppression & Leak Protection (Optional)
- After early warning is confirmed, projects commonly add clean agent suppression and leak detection as the next layer (you can create separate articles for each facility later).
