Honeywell 5800CMBOV Wireless Smoke & CO Detector

The Honeywell Home Resideo 5800CMBOV is a 345 MHz wireless combination smoke, heat, and carbon monoxide detector designed for compatible 5800 Series alarm systems. Featuring photoelectric smoke sensing, electrochemical CO detection, and 135 F fixed-temperature heat detection, it provides monitored fire and carbon monoxide protection through three dedicated alarm panel zones. The detector includes an 85 dB sounder, English/Spanish voice announcements, 360-degree visual alarm indicators, and a 10-year CO sensor. Powered by four CR123A lithium batteries, it supports supervised wireless communication, maintenance alerts, and low-temperature reporting.

Honeywell Resideo 5800CMBOV Wireless Smoke, Heat and CO Detector

The Honeywell Home Resideo 5800CMBOV Wireless Smoke and Carbon Monoxide Detector is a multi-criteria life safety device designed to provide smoke, heat, and carbon monoxide detection through a single wireless unit. Part of Resideo's 5800 Series wireless security product family, the 5800CMBOV combines photoelectric smoke detection, electrochemical carbon monoxide sensing, and fixed-temperature heat detection to identify hazardous conditions in residential and compatible monitored security installations. The detector also incorporates infrared sensing technology as part of its manufacturer's multi-criteria detection design, helping its processing algorithms distinguish potential fire conditions from environmental disturbances. Operating at 345 MHz, the device communicates with compatible Honeywell Home and Resideo control panels, supporting monitored alarm reporting without dedicated detector wiring. Its combination design reduces the number of separate life safety devices required for installations needing both smoke and carbon monoxide monitoring.

The 5800CMBOV features a photoelectric smoke sensor with a sensitivity range of 1.33% to 2.60% obscuration per foot, an electrochemical CO sensor with a manufacturer-rated 10-year service life, and a 135 F (57 C) fixed-temperature heat sensor. Advanced signal-processing algorithms and automatic sensor drift compensation help maintain smoke detection performance as environmental conditions change or dust accumulates. The detector provides separate smoke, heat, and CO reporting through three individually enrolled control panel zones, allowing the security system to distinguish between emergency conditions. An additional low-temperature warning function reports when the surrounding temperature drops below 41 F (5 C). The device also transmits supervised status messages approximately every 60-70 minutes and reports tamper, low-battery, maintenance, trouble, and CO sensor end-of-life conditions to compatible alarm panels.

Designed for audible and visual fire and carbon monoxide emergency notification, the Honeywell 5800CMBOV incorporates an 85 dB piezoelectric sounder and integrated voice speaker with selectable English or Spanish announcements. Smoke and heat alarm conditions activate a Temporal 3 audible warning pattern, while carbon monoxide detection produces a Temporal 4 pattern with a voice instruction directing occupants to move to fresh air. A 360-degree visual indication system uses red illumination for smoke and heat emergencies and blue illumination for CO alarms, while a multicolor status LED indicates normal operation, testing, maintenance, and trouble conditions. Separate smoke and CO Test/Hush buttons allow technicians to perform local functional checks and temporarily silence qualifying alarms according to the manufacturer's instructions. These features help occupants distinguish between different emergency conditions while providing installers with convenient system testing and diagnostic capabilities.

The Resideo 5800CMBOV operates from a 6VDC battery supply using four Panasonic CR123A lithium batteries, eliminating the need for hardwired power connections. Its universal mounting plate supports installation on approved ceilings, walls, drywall surfaces, and common electrical backboxes, simplifying both new installations and wireless security system upgrades. The detector measures approximately 6.2 inches (157.5 mm) in diameter and 1.99 inches (50.5 mm) high, with a weight of 14.3 ounces (406 grams). Designed for ordinary indoor residential environments, it operates between 32 F and 100 F (0 C to 38 C) and supports relative humidity from 20% to 95%. The US model complies with ANSI/UL 268 and UL 2075, with CO sensitivity evaluated to UL 2034. The 5800CMBOV replaces the earlier Honeywell 5800COMBO detector and requires a compatible 5800 Series wireless receiver and alarm control panel supporting separate smoke, heat, and carbon monoxide zone programming. Its combination of supervised wireless operation, multi-threat sensing, voice notifications, and long-life CO detection provides a practical life safety solution for compatible Honeywell and Resideo security systems.
