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

Provides reliable supervised status at the panel and Total Connect 2.0 when installed, enrolled, and range-tested correctly.

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.

Use official Resideo install PDFs and install guides for exact wiring, enrollment, and firmware — specifications vary by SKU and region.

FAQs

Why does my zone show trouble?

Most common: low battery, tamper open, out of range, or wrong sensor type for the panel receiver (5800 Series vs SiX wireless).

How do I replace a sensor?

Delete old zone in installer programming, enroll replacement using Learn mode, and test walk test at final location.

Will Total Connect 2.0 show this device?

When the panel has active interactive service, enrolled zones appear in the Total Connect 2.0 app with status matching the panel.

How do I test after installation?

Use panel walk test, zone status, and (if monitored) central station test per dealer procedure.

Can I mix 5800 and SiX sensors?

SiX sensors require ProSeries or Lyric; 5800 needs a 5800 receiver transceiver hardware — they do not enroll on the standard 345 MHz receiver alone.
