ELK ELK-AEXRFA Control Panel Receiver

Easily add wireless RF sensors and two‑way transceivers to ELK control systems for reliable security and monitoring. The ELK Products ELK-AEXRFA control panel receiver adapter connects an Alarm Engine RF receiver/transceiver to the Alarm Engine RS-485 data bus (E27 control board), enabling secure, bus‑controlled wireless integration for intrusion, surveillance, and remote monitoring applications. It accepts either the ELK-AERF3 319.5MHz receiver or the ELK-AERF9 two‑way transceiver, drawing 27mA (board only) and up to 112mA with an AERF9 installed, while operating at standard 12 VDC. Installers benefit from a compact housing and straightforward bus connection that lets you deploy up to four AEXRFA adapters for expanded wireless coverage without additional control panels. Built for professional security and commercial surveillance projects, this adapter minimizes wiring time and simplifies system architecture. Add the ELK-AEXRFA to retrofit projects or new builds to extend sensor reach and improve monitoring reliability — order now to streamline your next security installation.
