Compliance overview
Scope and applicability
This standard applies to the design, manufacturing, and inspection of user information transmission devices used in urban fire protection remote-monitoring systems installed in general industrial and civil buildings. It is mandatory for manufacturers producing transmission devices for the Chinese market. The standard categorizes these devices into general-purpose types (with local display and query functions) and gateway types (without local display). It does not apply to the monitoring center software or the fire alarm systems themselves, which are covered by other parts of the GB 26875 series.
Technical requirements
The standard specifies comprehensive technical requirements for transmission devices, focusing on appearance, main components, and operational functionality. Devices must feature clear indicator lights and displays, with specific requirements for sound pressure levels and visibility under certain lighting conditions. Manufacturers must ensure devices can receive and transmit fire facility status information within 10 seconds. The standard mandates features like manual alarm, self-inspection, breakpoint continuation, and time synchronization reception. Regarding electrical and power requirements, the standard outlines criteria for main and backup power supplies, including automatic conversion and backup battery capacity. Devices must withstand specified power parameter fluctuations and maintain insulation performance and electrical strength. Compliance with strict electromagnetic compatibility (EMC) performance is required to ensure stability under various interference conditions. Environmental durability is also a core requirement. The devices must endure climatic environmental tolerance tests, including low-temperature operation and constant damp heat, as well as mechanical environmental tolerance tests for vibration and impact. Additionally, the standard sets forth software requirements, mandating that programs be stored in non-volatile memory and protected against unauthorized modifications. Operation levels must be clearly defined and protected through identity verification.
Testing methods
The standard details rigorous testing methodologies to verify compliance. Key tests include the fire facility status information reception and transmission test, which measures response times and prioritization of fire alarms. Other critical evaluations involve power parameter fluctuation tests, insulation resistance tests, and electrical strength tests. Electromagnetic compatibility is assessed through various immunity tests, such as radio-frequency electromagnetic field radiation and electrostatic discharge tests, referencing standards like GB/T 17626.2. Environmental resilience is verified through low-temperature operation, constant damp heat, and vibration (sine) tests in accordance with GB/T 16838.
FAQs
