Frequently Asked Questions About Wanlin 4G Smart Gas Alarm with Auto Shutoff


Q1: What certifications does the WL-GA200 carry for international import?


A: The WL-GA200 is certified to CE (EMC/LVD/RED), EN54 (fire detection), EN50291 (gas detection), FCC Part 15, RoHS 2.0, and REACH. Additional certifications (UL 1480, ATEX, IECEx, SASO, EAC, INMETRO) are available for specific product variants and target markets. Full certification documentation packages are provided with every shipment for customs clearance and regulatory compliance.


Q2: What is the minimum order quantity and lead time for export?


A: Standard MOQ is 100 sets for stock products with standard specifications. OEM/ODM customization (custom branding, packaging, firmware, sensor type) starts from 1000 sets. Standard lead time is 20-25 working days. Urgent orders can be expedited to 7-10 working days. We support FOB Shenzhen, CIF, and DDP delivery terms.


Q3: How does the 4G cloud platform work? Is there a recurring fee?


A: The WL-GA200 connects directly to 4G LTE cellular networks — no WiFi or gateway required. Each device includes a built-in 4G SIM slot. The cloud platform provides real-time gas concentration monitoring, alarm history, device status, multi-channel alerts (APP push, SMS, phone call, WeChat), and remote configuration. The cloud platform is included free with device purchase — no recurring software licensing fees. 4G data costs are minimal (approximately $0.50-1.00 USD per device per year for standard alarm reporting).


Q4: Can the WL-GA200 automatically shut off gas supply?


A: Yes. The WL-GA200 supports solenoid valve linkage for automatic gas shutoff. When gas concentration exceeds the alarm threshold, the device triggers the solenoid valve to close within 1 second, cutting off gas supply to prevent explosion. Compatible with DN15-DN50 solenoid valves (pulse-driven or motor-driven). The valve can also be manually controlled via APP. Valve shutoff confirmation is sent to the cloud platform.


Q5: Can Wanlin products integrate with existing building management systems and gas utility platforms?


A: Yes. The WL-GA200 supports integration via 4G LTE Cat.1 + WiFi, RS485 Modbus protocol, and open API. For institutional deployments, our system integrates with major BMS/SCADA platforms, gas utility monitoring systems, and fire alarm control panels. Our technical team provides full integration documentation, SDK, and API support. Custom protocol adaptation is available for OEM/ODM customers.


Q6: What warranty and after-sales support do you offer for international buyers?


A: Standard warranty is 2 years from shipment date, covering manufacturing defects (sensor lifespan: 5-10 years depending on type). We provide remote technical support (English/Spanish/Arabic/French), online training sessions, spare parts availability (1% free spare parts with orders), and annual maintenance training. Extended warranty (3-5 years) and on-site support are available for large projects. Our international service team responds within 24 hours.


Q7: How can I request samples and get a quotation?


A: Sample requests can be sent to wanlinfirecontrol@163.com with your target market, required certifications, gas type (methane/LPG/natural gas), and estimated annual quantity. Samples are typically shipped within 3-5 working days via DHL/FedEx. Formal quotations include unit price, MOQ, lead time, certification documentation, and shipping options. We welcome factory visits — our Shenzhen facility is open for audits by appointment.
