NDR Lamp Memory Master Station with External Control Capability
NDR-10 NDR-20 NDR-30 NDR-40 NDR-10A NDR-20A NDR-30A NDR-40A
- 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.
