Linear's ACT-31B and ACT-34B offer a cost effective means of incorporating the security and convenience of block coded transmitters into nearly any access control application. Both models are sequentially precoded at the factory with unique ID codes, as well as facility codes. This coding combination represents the same level of security as a traditional Wiegand card.
ACT series transmitters are small enough to be carried on a key ring in a pocket or purse. The 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. The ACT-34B is a four-channel model that sends a unique signal from each of its four buttons. It is ideal for applications that require access control for both entry and exit, as well as when multiple remote control functions are needed, such as gate and multiple garage access.
Programming ACT-31B or ACT-34B series transmitters 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.
