Baseline’s biCoders work with Baseline’s biLine™ two-wire technology to create the only true bi-directional two-wire devices in the industry. Baseline’s biCoders not only receive commands from the controller, they also send real-time information back to the controller. Plus, Baseline’s biCoders have built-in diagnostic LED lights that tell you at a glance whether the device is working. This smart technology also enables you to assign any biCoder to a zone or function from the controller after the biCoder has been installed in the field. With a multi-station biCoder, you can assign any station to any zone, in any order.
