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.

How do I test after installation?
Use panel walk test, zone status, and (if monitored) central station test per dealer procedure.
Can I mix 345 MHz and ePlus sensors?
ePlus 900 MHz sensors require XCVR2 transceiver hardware — they do not enroll on the standard 345 MHz receiver alone.
