LEF Series
Audio Only Intercom
The LEF Series is a selective calling, open-voice audio intercom system designed for push-to-talk communication between door and master stations. With a push of a button from the master station, it triggers a simple door release activation unlocking the door controlling access and entry. This basic, but rugged audio intercom system is designed to meet a wide variety of configurations. Mix and match components, as well as integrate with CCTV and paging systems. Audio door stations are weather resistant, tamper proof, and backed by our superior service. Integrate with the AC Series for a more comprehensive access and entry control security solution.
