Overview
IEC 60839-5-3:2016 defines minimum equipment requirements for the Receiving Centre Transceiver (RCT) used in alarm transmission systems. Part of the IEC 60839 series, this standard focuses on the performance, reliability, resilience, security and safety characteristics of RCTs installed in an Alarm Receiving Centre (ARC). The RCT’s role is to monitor alarm transmission paths (ATPs), receive alarm and status messages from supervised premises, forward messages to annunciation equipment (AEs), and send acknowledgements to supervised premises transceivers (SPTs). IEC 60839-5-3 complements the general ATS requirements given in IEC 60839-5-1.
Key Topics
The standard addresses functional and test requirements for RCTs, including:
- RCT classification and scope - minimum equipment features needed whether the RCT is stand‑alone or integrated into AE.
- Access levels and remote access - definitions and tests for logical access, user roles and secure remote management.
- Software management - controlled uploading/downloading of firmware and software, and related test procedures.
- Data and parameter storage - requirements for reliable storage of configuration, logs and events.
- Monitoring and fault notification - detection and reporting of ATP/ATS failures for single and dual path systems.
- Interfaces to annunciation equipment (AE) - interoperability and message forwarding requirements.
- Event recording and logging - required events to be recorded, clock resolution, log endurance and user identification.
- Modes of operation - store‑and‑forward and pass‑through operation constraints and tests.
- Information and substitution security - protection against message tampering, substitution and denial-of-service.
- Redundancy and resilience - RCT redundancy requirements to ensure continuity of alarm reception.
- Test methods - laboratory, functional and environmental tests (referenced IEC 62599 series).
Applications / Who Uses It
IEC 60839-5-3 is intended for:
- Alarm transmission service providers and Alarm Receiving Centre operators (ARCs)
- Alarm system manufacturers and integrators designing or supplying RCTs
- Telecommunication and internet service providers supporting ATS
- Fire departments, insurers, and end users specifying reliability and security requirements
- Certification bodies evaluating RCT compliance
Practical applications include selecting compliant RCT hardware/software, specifying ARC acceptance criteria, and ensuring interoperability between SPTs, RCTs and annunciation equipment for monitored security and fire alarm systems.
