Access your commercial doors is as easy as the push of a button with the Allstar 831T transmitter. Made for use with a single commercial door or gate, this control transmitter features three simple pushbuttons for Open, Close and Stop functions. In addition, the Stop function is colored red for easy identification in case of an emergency. There is also a slight beveling around each of the pushbuttons, which will help to avoid accidentally triggering the transmitter if something touches or leans on the device. The Allstar 190-107483 831T one-channel door transmitter is compatible with these receivers: 831R, 831RJ, MVP-3CH-24V-3T-4W, MVP-3CH-12V-8W-FC, MVP-3CH-24V-8W-FC, MVP-RE-24V-8W-FC, and MVP-MR.
