DESCRIPTION:
The NDRM Rack Mount Intercom System provides
a convenient and reliable means to communicate
and confirm access to secured areas from one
central control office. The master station is equipped
with communication and selective control of
external devices for up to 20 locations. The add-
on panel can accommodate up to 40 locations with
selective control. Each panel occupies three rack
spaces in a standard EIA 19” rack.
All of the controls for the system are located on the
front of the master panel for easy access. A jack is
provided for the modular handset (or telephone
headset) for more private communication.
