Every year, fires cause significant loss of life and property damage globally. Early detection is the most effective way to prevent catastrophic outcomes. A properly installed Smoke and CO composite detector can detect smoke particles at the earliest stage of a fire, providing critical time for evacuation and response.
Wanlin Fire Control is committed to advancing fire detection technology. Our Smoke and CO composite detector products incorporate the latest sensing innovations, including dual-wavelength photoelectric chambers, advanced algorithms to distinguish real smoke from dust and steam, and intelligent self-diagnostic features that ensure the detector is always operational.

Yes, our Smoke and CO composite detector is ideal for residential applications. Battery-powered models are perfect for existing homes where wiring is impractical, while hardwired models with battery backup meet new construction code requirements. All residential models feature easy-test buttons and low-battery warnings for homeowner convenience.
An addressable Smoke and CO composite detector has a unique digital address on the fire alarm loop, allowing the control panel to identify exactly which detector has activated. This enables precise location identification, individual detector sensitivity adjustment, and detailed event logging. Conventional detectors group multiple units on a zone circuit with zone-level identification only.
The maximum number depends on the fire alarm control panel specifications — typically 127 to 250 addressable devices per loop. Our detectors have low current consumption, maximizing the practical device count. We can provide loop-loading calculations for your specific panel model to ensure compliance.
For kitchen applications, we recommend heat detectors or multisensor detectors with heat-priority algorithms rather than smoke-only detectors, as cooking fumes can cause nuisance alarms. For bathrooms, moisture-resistant models should be selected. Contact our technical team for application-specific recommendations.
Wireless Smoke and CO composite detector systems use radio frequency communication (LoRa, Zigbee, or proprietary protocols) to connect detectors to a central gateway or control panel. They are ideal for heritage buildings, temporary installations, and situations where cabling is difficult. Battery life typically exceeds 3-5 years with regular status monitoring.
Our after-sales service includes: technical support by phone, email, and video call; warranty claim processing; spare parts supply; product replacement for defective units; and ongoing technical consultation. Response time for support inquiries is within 24 hours during business days.
Yes, our Smoke and CO composite detector products are ROHS compliant, meaning they are free from hazardous substances including lead, mercury, cadmium, and other restricted materials. We use recyclable packaging materials where possible and continuously work to reduce the environmental footprint of our manufacturing operations.
