Honeywell 5800COMBO Wireless Smoke/Carbon Monoxide Detector
The Honeywell 5800COMBO Wireless Smoke/Carbon Monoxide Detector is a combination life-safety sensor designed to help protect people and property from smoke, fire, and carbon monoxide hazards. Instead of installing separate smoke and CO sensors, this device combines multiple detection technologies into one wireless detector for compatible Honeywell Home and Resideo 5800 Series alarm systems.
This detector is commonly used in residential and light commercial alarm systems where monitored smoke and carbon monoxide protection is needed. When properly programmed into a compatible alarm panel, the 5800COMBO can send alarm signals for smoke, heat, and carbon monoxide conditions based on the system setup.
Compatible Alarm Systems
The Honeywell 5800COMBO is designed for compatible Honeywell Home and Resideo alarm panels that support 5800 Series wireless life-safety devices. Compatibility should always be confirmed before ordering, especially when adding the detector to an existing system or replacing an older smoke or CO sensor.
Combination Smoke and Carbon Monoxide Detection
This detector provides both smoke and carbon monoxide detection in a single wireless device. The smoke detection helps monitor for airborne smoke particles, while the carbon monoxide sensor helps detect dangerous CO gas that may be produced by fuel-burning appliances, vehicles, fireplaces, or other sources.
Multi-Threat Detection Technology
The 5800COMBO uses multiple sensing elements to help detect real fire and carbon monoxide conditions while reducing nuisance alarms. This makes it a strong option for life-safety applications where reliable detection and alarm communication are important.
Wireless Installation
The wireless design makes the Honeywell 5800COMBO a practical option for adding smoke and CO protection without running new alarm wiring. It can be installed in approved locations based on manufacturer instructions, property layout, and applicable safety guidelines.

Important Compatibility Notice
Before purchasing, please confirm that your alarm panel supports Honeywell Home or Resideo 5800 Series wireless smoke and carbon monoxide detectors and is compatible with the Honeywell 5800COMBO.
This detector is not a universal smoke or carbon monoxide alarm. It is intended for compatible 5800 Series wireless alarm systems and may not work with 2GIG, Qolsys, DSC, PowerG, or other alarm systems unless the specific panel configuration supports this device.
Programming may require installer access to your alarm panel. Smoke, heat, carbon monoxide reporting, zone programming, monitoring response, and notification features may vary based on panel model, firmware, service provider, and monitoring plan.
Smoke and carbon monoxide detectors must be installed, tested, and maintained according to the manufacturer instructions and applicable safety guidelines. For monitored fire or CO dispatch, the detector must be properly programmed and connected to an active monitoring service that supports those alarm signals.
