Compliance overview
Scope and applicability
This standard applies to user information transmission devices used in urban fire remote-monitoring systems installed in general industrial and civil buildings. It is specifically designed for devices that transmit fire alarm and facility status information to a monitoring center. It does not cover the monitoring center software or network protocols themselves, which are addressed in other parts of the GB 26875 series.
Technical requirements
This standard specifies the technical requirements for user information transmission devices used in urban fire remote-monitoring systems. The standard mandates that devices must be capable of receiving and transmitting fire alarm information and building fire facility status to a monitoring center within 10 seconds. Devices must prioritize fire alarm and manual alarm signals over other operational data. Key requirements include manual alarm functionality, self-check capabilities, and power supply redundancy with automatic switchover between main and backup power. The standard also defines strict electromagnetic compatibility (EMC) and environmental endurance criteria, ensuring reliable operation under electrical interference, temperature extremes, and mechanical vibration. Software must be stored in non-volatile memory and protected against unauthorized modifications. Compliance with these requirements is mandatory for market access.
Testing methods
The standard outlines a comprehensive testing protocol to verify compliance, including functional tests for alarm transmission, power supply switchover, and fault alarm mechanisms. It mandates insulation resistance and electrical strength tests to ensure safety. Environmental reliability is assessed through low temperature and damp heat tests, while mechanical robustness is verified via vibration and collision tests. Electromagnetic compatibility is evaluated using methods aligned with the GB/T 17626 series for immunity to electrostatic discharge, radiated electromagnetic fields, and electrical fast transients.
FAQs
What products are covered under GB 26875.1-2011?
It applies to user information transmission devices installed in general industrial and civil buildings as part of an urban fire remote-monitoring system. It does not apply to other system components like communication servers or management software.
