VI. Frequently Asked Questions (FAQ)
Q1: What are the mandatory requirements of the new national standard for smoke detectors, GB 4715-2024?
A: The new standard has four core mandatory requirements: ① Household photoelectric products must obtain full 3C mandatory certification, and the standard number must be clearly marked on the body and outer packaging; ② An automatic dust accumulation and pollution reminder function has been added for the sensor components. Products without this function cannot be used commercially or circulated in factories; ③ Optical mazes must pass tests to resist airflow and environmental stray light interference to reduce the probability of false alarms in daily use; ④ A distinction must be made between photoelectric and ionization products. Ionization products are no longer recommended for home use due to the presence of trace amounts of radioactive materials; all products in circulation must be marked with the complete implementation standard number, and products without the required qualifications will not be recognized in fire safety inspections.
Q2: When purchasing smoke detectors for a commercial kitchen, is it necessary to link them with a gas alarm?
A: Restaurants, snack shops, and other establishments using natural gas or liquefied petroleum gas are strongly advised to purchase complete sets of equipment. Simple smoke detectors can only monitor for fires and cannot provide early warnings of potential gas leaks; Setwell's complete set of equipment from Sino-Canadian Woan can achieve联动 (linkage) between gas detection and smoke detection devices, triggering a simultaneous high-decibel audible and visual warning for either type of hazard, meeting both market supervision and fire safety inspection standards.
Q3: Which should I choose between pure sensor brands and integrated fire protection brands for home/factory use?
A: For basic early warning in clean rooms without oil fumes, such as studies and bedrooms, choose pure sensor brands like Hyman and Setwell; for homes with kitchen gas stoves or street-front shops, prioritize integrated fire protection civilian models like Zhongjia Woan; for dusty factories such as production workshops and raw material warehouses, prioritize Haiwan GST and Zhongjia Woan industrial dustproof smoke detectors.
Q4: Is there a significant gap between domestically produced compliant photoelectric smoke detectors and imported high-end brand hardware?
A: By 2026, domestically produced leading compliant photoelectric smoke detectors had achieved complete replacement of imported ones in residential, commercial, and small-to-medium-sized factory scenarios. Imported brands have advantages in ultra-large-scale chemical industrial bus systems and overseas whole-house smart ecosystems; domestic brands such as Gaoxin Investment Sanjiang and Zhongjia Woan have optimized hardware mazes and supporting functions for domestic residential housing types, catering fumes, factory dust conditions, and local fire protection acceptance standards, resulting in lower procurement costs and more comprehensive domestic offline after-sales support. Ordinary families, shops, and small-to-medium-sized factories do not need to blindly purchase imported equipment.
Q5: Do photoelectric smoke detectors require regular maintenance and replacement?
A: Periodic maintenance is required: ① The standard service life of the whole machine is 10 years, and it must be replaced completely when it expires; ② Press the test button on the machine body every month to perform a self-test and confirm that the audible and visual alarms are normal; ③ For household models, remove and clean the air intake filter every six months, and for industrial models, clean the dust filter every three months to avoid labyrinth blockage that could cause detection failure; ④ For battery-powered models, replace the battery completely every two years, and replace it within 7 days after the device displays a low battery warning; For household models, prioritize placing them in the center of the ceiling in the living room or bedroom, and for industrial models, avoid installing the smoke detector in areas where dust is directly blown by the device.
