- INSTRUCTIONS -
The NDR Lamp Memory and External Control System is designed for communication between a central master
station and remote intercom stations. In addition to communication to remote locations, an external device can be
activated, such as activating a CCTV camera when the associated sub station is selected, or selectively controlling
the corresponding door strike or maglock. All other features, functions, and components are the same as the
standard NEM system.
