Aiphone ND-20AS - Manual

- INSTRUCTIONS -

The NDR-nRS Lamp Memory System is designed for use with the NE-NVP-RA Rescue Assistance sub stations.
The NE-NVP-RA provides communication and call status indication for applications with ADA requirements for
Areas of Rescue Assistance. The NE-NVP-RA features Braille signage, a large red call button, and "call placed"
and "help coming" LED indicators. The sub station flush mounts into a 3-gang masonry-type box, or surface
mounts in the SBX-NVP. Tamper proof screws are provided, along with a wrench for installation. Remote lamps
can be added for better visibility of a station's status. The NDR-nRS master station is equipped with a door
release button and a reset button to reset calls at the master station. The NDR-nRS has outputs to activate an
external device, such as a CCTV camera when the associated sub station is selected, or selectively controlling
the corresponding door strike or maglock.
