The Linear® act 31b transmitter is small enough to be carried on a key ring in a pocket or purse. The Linear® act 31b is a single-channel model used where only one remote control function is needed, such as an entrance gate that utilizes a free exit loop.
Programming Linear® act 31b transmitter into system memory is as simple as entering the first and last number of the coding block into the controller. Depending upon which type of controller, transmitters can be enrolled either by user-friendly programming software or manually at the controller keypad.
Compatible with Linear® 318MHz receivers and systems
