LDF Loudspeaker Master Station with External Control Capability
The LDF Loudspeaker Intercom and External Control System is designed for communication between a central master station and remote intercom stations. The LDF is an expanded feature version of the LAF-C/CA system. All information regarding installation other than the external control functions is included in the LAF-C/CA instructions. In addition to communication to remote locations, external devices can be activated, such as activating a CCTV camera when the associated sub station is selected, selectively controlling the corresponding door strike or maglock, or both.
