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.

- 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.
