Compliance overview
Scope and applicability
This standard applies to power supply monitoring systems for fire protection equipments installed in general industrial and civil buildings. It is mandatory for all manufacturers producing fire equipment power monitoring systems for the Chinese market. It covers the monitoring of AC/DC main and backup power supplies for fire protection devices, ensuring they operate correctly during overvoltage, undervoltage, overcurrent, and phase loss conditions. Systems installed in other environments may also refer to this standard.
Technical requirements
The standard specifies comprehensive requirements for the system's basic functions and main component performance. The monitoring system must consist of a fire equipment power status monitor, voltage sensors, and current sensors. The monitor must provide real-time status of both main and backup power supplies and issue audible and visual alarms within 100 seconds upon detecting faults such as power interruptions, circuit breaks, or voltage anomalies exceeding 110% or falling below 85% of the rated voltage. Key component requirements include strict specifications for indicator lights (yellow for faults, green for normal), audible devices (sound pressure level between 65dB and 115dB), and backup power capacity. The backup power must sustain the monitor in normal surveillance mode for at least 8 hours after a 24-hour charge. The system must also maintain a log of at least 999 fault records, retained for 14 days even after power loss. The standard mandates rigorous insulation resistance (minimum 20MΩ for terminals, 50MΩ for 220V AC inputs) and electrical strength (withstanding 1250V AC for 1 minute) to ensure safety. It also outlines specific requirements for electromagnetic compatibility, ensuring the system withstands electrostatic discharge, electrical fast transients, and surges as per GB/T 17626 series standards.
Testing methods
Testing procedures evaluate the system's resilience and reliability under various conditions. Key tests include the Basic Function Test for monitors and sensors, Insulation Resistance and Electrical Strength Tests for safety compliance, and a comprehensive suite of Electromagnetic Compatibility (EMC) Tests. Environmental endurance is verified through Low Temperature (Operating) Tests and Constant Damp Heat Tests, while mechanical stability is assessed via Vibration (Sine) Tests and Collision Tests. All tests follow the methodologies outlined in the GB 16838 and GB/T 17626 series standards.
FAQs
What products are regulated under GB 28184-2011?
GB 28184-2011 regulates power supply monitoring systems for fire protection equipments, including the main monitor, voltage sensors, and current sensors used in general industrial and civil buildings.
