Technical Parameters & Compliance Specifications (WL-SM604)

The WL-SM604 4G standalone smoke detector meets all 14 mandatory technical parameters required for CCCF certification under GB 20517-2006. These parameters ensure comprehensive fire detection capability, fault resilience, communication reliability, and regulatory compliance:

• Multi-Alarm Functions: The device is equipped with multiple alarm functions including under-voltage alarm, tamper/removal alarm, sensor fault alarm, product contamination alarm, network connection abnormal alarm, and platform connection abnormal alarm — ensuring comprehensive fault detection and real-time notification for continuous fire safety monitoring.

• Dual-Barrier Maze Sensor Structure: The sensor adopts a maze-type structure as the main protection design, combined with a stainless steel metal protective mesh at the smoke inlet, forming a dual barrier system. The maze structure effectively blocks solid objects with diameter exceeding 1.0mm from entering the device interior. A stainless steel metal filter mesh with aperture no greater than 0.6mm provides both insect-proof and dust-proof functionality while maintaining ventilation requirements and preventing fine particulate matter from entering.

• Manual Self-Test Function: The device features a manual self-test function that checks whether all device components are operating normally — including sensor response, communication module, battery status, and alarm output — enabling users to verify device integrity at any time without professional tools.

• Dual Light Path Photoelectric Technology: The device utilizes dual light path photoelectric sensing technology combined with 4G Cat.1 cellular communication. Power supply: DC6V battery with a service life of 3 years. The dual wavelength detection approach significantly reduces false alarms caused by steam, dust, and cooking fumes while improving detection accuracy for different types of smoke.

• Ultra-Low Power Consumption: Static current: no more than 10 microamps (10uA). Standby current: no more than 30 microamps (30uA). The ultra-low power consumption design ensures the 3-year battery life is achieved under normal operating conditions, minimizing maintenance frequency and battery replacement costs.

• Protection Area & Ingress Protection: Protection area: no less than 60 square meters per detector. Ingress protection rating: no less than IP31. The device provides reliable fire detection coverage for standard residential rooms, hotel guest rooms, office spaces, and small commercial premises while resisting dust and solid object ingress.

• High-Intensity Alarm Sound Pressure: Alarm sound pressure level: measured at 3 meters directly in front of the alarm, the fire alarm signal sound pressure level is no less than 95dB — ensuring the alarm is clearly audible throughout the protected area, including through closed doors in residential and commercial environments.

• GB 20517-2006 Standard & CCCF Certification: The device fully complies with the GB 20517-2006 national standard for standalone smoke fire detection alarms and carries the CCCF (China Compulsory Certification for Fire products) certification. Supports both screw mounting and adhesive backing mounting for flexible installation on ceilings or walls.

• Network Status Indication: The device provides comprehensive network status indication including at minimum: network connection failure, registration failure, and activation success prompts — enabling users and platform administrators to immediately identify communication issues and take corrective action.

• Network Access Licenses: The device holds a valid network access license certificate and a radio transmission equipment type approval certificate — ensuring legal compliance for cellular communication operation in regulated markets and facilitating customs clearance for export.

• Flame-Retardant Housing: The product housing, base, and all external components are manufactured from flame-retardant materials. When tested with flame applied 5 times, each application lasting 5 seconds, the housing shall not ignite or sustain combustion — preventing the detector itself from becoming a fire hazard source.

• National Type Test Report: The device complies with all requirements of GB 20517-2006 'Standalone Smoke Fire Detection Alarm' and has obtained a type test report issued by the National Fire Electronic Products Quality Supervision and Inspection Center — providing authoritative third-party verification of product quality and performance.

• CCC Mandatory Certification (3C): The device has obtained the China Compulsory Certification (3C/CCC) certificate issued by the Ministry of Emergency Management Fire Product Conformity Assessment Center, executing the national standard GB 20517-2006 'Standalone Smoke Fire Detection Alarm' — the mandatory product certification required for legal sale and installation in the Chinese market.

• CMA/CNAS Third-Party Test Report: The device carries a third-party inspection report bearing the CMA (China Metrology Accreditation) or CNAS (China National Accreditation Service) mark — demonstrating that all testing was conducted by an accredited laboratory meeting national standards for testing competence and measurement traceability.

All 14 parameters are verified by the National Fire Electronic Products Quality Supervision and Inspection Center type test report, CCC (3C) mandatory certification from the Ministry of Emergency Management Fire Product Conformity Assessment Center, and CMA/CNAS accredited third-party test report — providing full regulatory compliance for sale, installation, and fire code acceptance in regulated markets.

4G Smoke Detection Pain Points Addressed by Wanlin WL-SM604

International buyers in Los Angeles face common challenges when sourcing 4G standalone smoke detector products:

• Sensor Contamination & Insect Intrusion: Smoke detector sensors are vulnerable to dust, insects, and debris contamination, causing sensitivity drift and false alarms. Wanlin's maze-type sensor structure with stainless steel metal protective mesh forms a dual barrier — blocking solid objects >1.0mm and filtering particles through 0.6mm aperture mesh — providing insect-proof and dust-proof protection while maintaining ventilation.

• Incomplete Certification for Market Access: Most Chinese smoke detector factories provide no international certification. International distributors need CCCF/GB 20517-2006, CE, UL 217, EN 14604, network access license, radio type approval, CMA/CNAS third-party test reports, and flame-retardant housing certification. Wanlin provides complete certification packages from accredited laboratories with full compliance documentation.

• No Multi-Alarm Fault Detection: Most smoke detectors only alarm for smoke — no indication of sensor faults, battery issues, tamper, or communication failures. Wanlin's detectors feature comprehensive multi-alarm functions: under-voltage alarm, tamper/removal alarm, sensor fault alarm, product contamination alarm, network connection abnormal alarm, and platform connection abnormal alarm — ensuring all fault conditions are immediately detected and reported.

• Short Battery Life & Frequent Maintenance: Traditional smoke detectors require annual battery replacement, creating maintenance burden and risk of non-functional detectors when batteries die. Wanlin's 4G standalone smoke detectors feature DC6V battery with 3-year service life, ultra-low power consumption (static <=10uA, standby <=30uA), and low battery warning alarms — reducing maintenance frequency by 70% and ensuring continuous protection.

• High False Alarm Rate from Cooking & Steam: Standard photoelectric smoke detectors trigger false alarms from cooking fumes, shower steam, and dust — causing nuisance and alarm fatigue. Wanlin's WL-SM604/WL-SM606/WL-SM607 models feature dual light path photoelectric sensing, dual wavelength detection, and AI false alarm reduction algorithms — reducing false alarms by up to 90% while maintaining detection sensitivity.

Wanlin Fire Protection's WL-SM604 directly addresses these pain points with factory-direct quality, complete multi-certification packages (CCCF/GB 20517-2006/CE/UL 217/EN 14604), 4G Cat.1 cellular communication with cloud platform, dual light path photoelectric sensing, maze sensor with stainless steel mesh dual barrier, DC6V 3-year battery, multi-alarm fault detection, manual self-test, network status indication, network access license, CMA/CNAS test reports, AI false alarm reduction (select models), and full OEM/ODM customization including white-label cloud platform — all at 50-70% lower cost than Honeywell/Kidde/Nest.
