Frequently Asked Questions

Q: Are Wanlin Fire combination smoke and CO detectors certified and safe?

A: Yes. All detectors carry UL 217, UL 2034, EN 14604, CE, and RoHS certifications. Safety features include 10-year sealed battery, low battery warning, end-of-life signal, tamper-resistant design, and silence button.

Q: What sensor technology does the WL-SC-500 use?

A: The WL-SC-500 uses a dual-sensor approach: photoelectric smoke sensor for fast response to smoldering fires, and electrochemical CO sensor for accurate carbon monoxide detection from 0-999 ppm. This combination reduces false alarms by 40-60% compared to ionization-only detectors and provides superior fire and CO protection.

Q: Can the detectors be interconnected?

A: Yes. The WL-SC-500 supports both hardwired interconnect (compatible with existing Kidde and BRK systems) and wireless interconnect via 433MHz or Wi-Fi. When one alarm triggers, all interconnected units sound simultaneously and the voice alert announces the location.

Q: What combination smoke and CO detectors does Wanlin Fire manufacture?

A: Wanlin Fire manufactures a complete 6-model combination smoke and CO detector line: WL-SC-100 (basic battery-operated combination smoke and CO detector); WL-SC-200 (photoelectric combination smoke and CO detector with test and silence); WL-SC-300 (voice alert combination smoke and CO detector with digital display); WL-SC-500 (10-year sealed battery smart combination smoke and CO detector); WL-SC-700 (Wi-Fi interconnected smart combination smoke and CO detector); WL-SC-900 (commercial grade combination smoke and CO detector with relay output). All UL 217, UL 2034, EN 14604, CE, and RoHS certified.

Q: What is the MOQ and delivery time for Utrecht buyers?

A: MOQ starts at 100 units for wholesale, 500 units for OEM/ODM customization. Standard delivery: 12-15 days. Samples: 5-7 days. FBA-ready packaging, multi-language documentation, and certification test reports included. Dropshipping available for e-commerce partners in Utrecht and Netherlands.
