PAIN POINTS

Industry Pain Points

01
🔥

Electrical-Fire Hazards Hard to Detect in Time

Rising leakage, poor contact and overload heating are hidden hazards; conventional inspection rarely finds them before a fire breaks out, missing the optimal handling window.

02
💨

Smoke Detectors Cannot Warn of Electrical Faults in Advance

Conventional smoke detectors only alarm after smoke appears and cannot sense abnormal electrical parameters, providing no advance warning for electrical fires with severely lagging response.

03
🌡️

No Online Monitoring of Switchgear Temperature

Oxidized joints and rising contact resistance heat up switchgear interiors, but cabinet temperature cannot be monitored online; infrared inspection cycles are long with limited coverage, letting hazards accumulate.

04

Arc Faults Cannot Be Recognized

Arc faults from aging insulation are a major cause of electrical fires; conventional breakers cannot recognize them, leaving hazards until a fire ignites.

FAQ

FAQ

Conventional systems rely on smoke/heat detectors that only alarm after fire produces smoke or heat - a reactive response. FEXLINK's smart fire protection senses electrical parameters through ESF leakage monitoring, EST temperature monitoring and FA arc-fault monitoring, detecting rising leakage, abnormal temperature and arc generation hours or even days before ignition, achieving a fundamental shift from reactive alarming to proactive prevention and reducing electrical-fire risk by over 80%.
The FA Arc-Fault Monitoring Module complies with UL 1699B and captures arc current waveforms through high-frequency sampling. The current waveforms of fault arcs (series/parallel) differ significantly from normal load currents; the Wanxiang AI engine performs multi-dimensional feature extraction and pattern recognition to distinguish fault arcs from normal ones (such as motor start/stop and switching operations), achieving 97.2% recognition accuracy with an extremely low false-alarm rate.
The system supports multi-level linkage: level one is on-site audible/visual alarming via the CW gateway's siren/beacon; level two is remote notification through SMS, phone and APP push; level three is fire-system linkage with fire-fighting hosts; level four is automatic tripping where FECB Smart Breakers cut the faulty circuit on command. Alarm rules are flexibly configurable, triggering different linkage levels by hazard severity.
The system suits any site with electrical-fire risk: public buildings such as commercial complexes, offices, hotels, hospitals, schools and nursing homes; industrial sites including factory workshops, warehouses and substations; high-value facilities such as data centers and computer rooms; special sites including heritage buildings and historic districts; and densely populated areas such as residential communities and urban villages. Sensing terminals and alarm strategies can be configured by site risk level and protection needs.
