We are not a middleman. We are the source factory. We offer complete export solutions for dual sensor smoke detectors, dual technology smoke alarms, multi-criteria smoke sensors, combined photoelectric and ionization detectors, and dual sensing fire detectors. Our philosophy is simple: win-win cooperation, quality assurance, and exceptional service for every global partner.

Our Core Product Line – Dual Sensor Smoke Detection Deepened

Dual sensor smoke detectors combine two different detection technologies in a single unit, providing comprehensive fire protection for both fast-flaming and slow-smoldering fires. All products are designed to meet CE, RoHS, EN14604, UL217, and UKCA certifications.

1. Dual Sensor Smoke Detector

• Combines photoelectric and ionization sensors in one housing

• Detects both slow-smoldering fires (photoelectric) and fast-flaming fires (ionization)

• Reduced false alarms compared to single-sensor detectors

• Available in 9V battery, 10-year sealed battery, and hardwired with battery backup

• Interconnectable version available (wireless or hardwired up to 24 units)

2. Dual Technology Smoke Alarm

• Smart algorithms to analyze signals from both sensors

• Minimizes nuisance alarms from cooking, steam, and dust

• Self-diagnostics and drift compensation

• 85dB alarm with red LED flash pattern indicating alarm source (photoelectric or ionization)

• Hush button with enhanced false alarm rejection logic

3. Multi-Criteria Smoke Sensor

• Advanced detection combining photoelectric, ionization, temperature, and optional CO sensing

• Intelligent fire discrimination reduces false alarms by up to 70%

• Suitable for high-value environments (data centers, museums, hospitals)

• Addressable communication for building management system integration

• Real-time environmental monitoring and fault reporting

4. Combined Photoelectric & Ionization Detector

• Dual chamber design with independent calibration for each sensor

• Photoelectric chamber optimized for smoldering fires (large smoke particles)

• Ionization chamber optimized for flaming fires (small combustion particles)

• Automatic selection of fastest response technology

• Meets NFPA 72 requirements for residential and commercial applications

5. Dual Sensing Fire Detector

• Integrated sensor fusion technology

• Continuous self-checking of both sensing elements

• Remote test and silence capability (for professional systems)

• Low current consumption for extended battery life (up to 10 years)

• Tamper-resistant design with childproof locking mechanism

All products undergo 100% pre-shipment quality control including dual-sensor calibration verification, environmental chamber testing, and battery life validation. Multi-language user manuals available.

Technical Advantages of Dual Sensor Technology

Why Dual Sensor? Single technology detectors have limitations. Photoelectric detectors excel at smoldering fires but may respond slower to fast-flaming fires. Ionization detectors respond quickly to flaming fires but are more prone to nuisance alarms. Dual sensor combines both for comprehensive protection.

Photoelectric Technology

• Uses light-scattering principle

• Best for smoldering fires (upholstery, bedding, electrical insulation)

• Lower false alarm rate from cooking

Ionization Technology

• Uses radioactive material (Americium-241) within strict safety limits

• Best for fast-flaming fires (paper, wood, flammable liquids)

• Responds to smaller combustion particles

Multi-Criteria Enhancement

• Some models add temperature and carbon monoxide sensing

• Smart algorithms analyze multiple inputs before triggering alarm

• Dramatically reduces false alarms in challenging environments

Wanlin's dual sensor smoke detectors are factory calibrated to ensure both sensors work harmoniously. The detection algorithm prioritizes the faster response while cross-validating to prevent false triggers.
