Honeywell Home 5800COA ULC Listed - Carbon Monoxide Detector Overview

5800 Series smoke, heat, or CO wireless life-safety transmitter — supervised fire/CO zone on compatible panels (5800CO, 5800COMBO, smoke SKUs).

Life-safety devices have stricter placement and testing requirements than burglary sensors. Follow NFPA/local code, use professional monitoring where required, and never substitute takeover modules for fire or CO hardwire.

What This Device Does Well

Before You Service or Replace One

• Device age — smoke/CO sensors expire; replace per label date.
• Zone type — fire vs burglary programming differs; do not bypass without authority.
• FireFighter placement — acoustic path to standalone smoke alarms.
• Monitoring — central station fire test procedures for monitored accounts.
