Overview
2GIG smoke, heat, freeze, or CO detector — life-safety wireless initiating device; requires code-compliant placement and monitoring where applicable.
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.
