IEC 62642-2-3:2010

Overview - IEC 62642-2-3:2010 (Microwave detectors)

IEC 62642-2-3:2010 specifies requirements and tests for microwave intrusion detectors used inside buildings as part of intrusion and hold‑up alarm systems. It defines how detectors must detect intruders by emitting microwave radiation and analysing returned signals, and it covers detectors for security grades 1 to 4 and environmental classes I to IV (see IEC 62642-1 and IEC 62599-1). This part applies to specific or non‑specific wired or wire‑free detectors and excludes outdoor detectors and system interconnections.

Key topics and technical requirements

• Security grades & environmental classes
  • Support for Grades 1–4 (increasing functional and signalling requirements).
  • Environmental classification per IEC 62599‑1 (Classes I–IV).
• Core functions and event processing
  • Mandatory/optional event handling (Table summary): intrusion, tamper, masking, significant range reduction, low supply voltage, total loss of power, local/remote self tests.
  • Signal/message generation rules and recommended prioritisation (e.g., intrusion, fault, masking).
• Detection and testing
  • Requirements for basic detection tests, walk tests (standard walk‑test target and simulated targets), and masking tests.
  • Annexes providing walk‑test diagrams, test magnets, masking materials and test matrices.
• Operational and immunity requirements
  • Tests for immunity to incorrect operation, electrical requirements (power, low‑voltage behaviour), EMC considerations (see IEC 62599‑2), and tamper security.
• Marking, documentation and self‑test
  • Mandatory identification, documentation and provisions for local and remote self‑testing and fault signalling.

Practical applications - who uses this standard

• Manufacturers designing and certifying indoor microwave detectors.
• System integrators and security installers selecting detectors for building intrusion systems.
• Test laboratories and certification bodies performing compliance and performance testing.
• Security consultants and facility managers specifying detectors by required security grade and environmental class.
• Typical use cases: perimeter-free interior detection zones, retail and office intrusion detection, integration with control and indicating equipment (CIE), wired or wireless alarm subsystems.
