Compliance overview
Scope and applicability
This standard specifies the requirements and testing methods for household fire safety systems installed in residential environments. It applies to four types of systems (Type A, B, C, and D) ranging from centrally managed systems for residential communities to standalone systems for individual homes. It is mandatory for manufacturers producing fire alarm equipment intended for domestic use in China. The standard covers controllers, detectors, manual switches, and monitoring devices.
Technical requirements
The standard outlines comprehensive general requirements for system components, including specifications for indicator lights, fuses, wiring terminals, and backup power supplies. Equipment must meet an enclosure protection rating of IP30 as per GB 4208. Manufacturers must ensure that all components use standard communication protocols and maintain system compatibility. For household fire alarm controllers, the standard mandates specific functionalities such as fire alarm reception, monitoring, and fault alarm capabilities. Controllers must display information in Chinese, provide audible and visual alarms with a minimum sound pressure level, and support automatic dialing of at least two phone numbers. Controllers must also seamlessly switch between main and backup power without causing false alarms. The requirements for fire detectors (smoke, heat, and combustible gas) and manual alarm switches dictate that they must emit audible signals and transmit data to the controller. Combustible gas detectors must be capable of controlling specialized electric valves for gas pipelines. Additionally, control center monitoring equipment must synchronize information with household controllers and maintain detailed alarm logs.
Testing methods
The standard defines a rigorous testing protocol to verify compliance. Key tests include functional tests for all system components, insulation resistance and electrical strength tests, and EMC (Electromagnetic Compatibility) tests such as electrostatic discharge and surge immunity. Environmental reliability is assessed through low-temperature operation, constant damp heat, vibration, and collision tests.
