BEA 10TD900HH1U Universal Hi-Accessability Transmitter 900 MHz works with the BEA 10BR2-900 | 2 Relay Logic Module w/Built-In 900 Series Receiver and is a keyring single-button door/gate opener remote. One-step programing, out-of-the-box functionality when paired with Universal Receiver. These universal transmitters all broadcast through the same hard-coded protocol over the 900 MHz frequency. *Because of same signal protocol, this transmitter is intended for accessibility* and for lower-security settings as enclosed/interior systems, gates, portals; or institutional needs.
