Overview
RAS arming station or alphanumeric keypad — Challenger/Tecom area arming station with LED or LCD status (CA111x, 4/8/16-area RAS).
On Interlogix 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 TX-E and Challenger wired devices?
TX-E needs Simon (or 319.5 MHz host); Challenger DGP needs wired or listed wireless paths transceiver hardware — they do not enroll on the standard 345 MHz receiver alone.
