How Electrical Fire Monitoring Systems Are Detecting Fires Before They Start
Electrical Fire Monitoring System (EFPS) is a dedicated early-warning arrangement that continuously tracks residual current (leakage) and temperature parameters in electrical circuits and equipment. When any measured value exceeds a preset threshold the system issues an alarm signal, generates a control output, and indicates the precise location of the anomaly.
ABB – The Precision Watcher
- ABB brings Swiss-rooted engineering to electrical fire prevention with its dedicated EFPS Elite series and arc-fault detection devices that continuously scan for residual currents and overheating.
- A single wall-mounted CME unit can handle up to 512 monitoring points and expand to 1,024, covering temperature, residual current, and full electrical parameters on circuits up to 2,000 A.
- In a recent high-profile project, ABB’s AFDD technology was installed during the full electrical renovation of Germany’s 1,200-year-old Aachen Cathedral to stop dangerous arcs before they start.
- The company employs around 110,000-112,000 people across roughly 100 countries, with its Electrification business alone generating $17.4 billion in 2025 revenue and supporting tens of thousands of installations in buildings, utilities, data centers, and transport.

Siemens – The Smart Infrastructure Sentinel
Siemens integrates residual-current monitoring devices (such as SENTRON 5SV8 COM) and arc-fault detection units into broader building and power systems so faults are flagged long before they become fires. The devices support early pre-alarms without unnecessary shutdowns and pair with digital tools like Fire Digital Twin and Fire Install Suite.
At the 2026 NFPA Conference in Las Vegas, Siemens highlighted these advances alongside new semiconductor-based protection and residual-current functions for high-availability sites such as data centers. The group employs more than 300,000 people worldwide, with Smart Infrastructure contributing around €23 billion in turnover and tens of thousands of specialists focused on buildings, electrification, and fire safety across dozens of countries.
