Overview
2GIG outdoor wireless contact — weather-rated magnetic contact for gates, sheds, and exterior openings (including encrypted DW30 / ePlus outdoor SKUs).
On 2GIG systems, wireless devices are supervised zones on the panel — tamper, low battery, and missing signals appear as trouble conditions that may block arming depending on panel programming.

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.
