7.1 Corridor Display (NICD)
The NICD is a supplemental IP based corridor display suitable for use in teleCARE IP, and
contains a LAN interface for connection to the teleCARE IP LAN network.
The NICD has a large character, 3-color (Red/Green/Amber) message display and a signaling
buzzer. It is available as a single or double sided unit with a 6-character or a 12-character
display.
Figure 159. 6 and 12 character Corridor Display (NICD)
WARNING: The NICD equipment described in this section is for supplementary purposes only, is
not evaluated to UL 2560 and is not part of the teleCARE IP system UL listing.
From the built-in web interface the basic configuration of the NICD can be adjusted, for example the
IP address, host name and communication port.
General text display settings can be set in the NISM2. Up to 50 NICDs can be added to a
single NISM2.
The NISM2 is used to define such things as message display time, number of stored messages, the
color of the displayed message depending on message priority and buzzer options. The NICD display
mode can be constant or scrolling.
The display mode can be set to constant (with short blank period in between) or to scrolling
(from bottom to top) when there are two or more active calls to be displayed. The NICD can
display up to 30 different messages. If the maximum number of messages is reached, the
oldest message with the lowest priority will be cleared first. When the display is not
showing any messages (idle), it can be configured to show the time/date or any other type
of welcome message.
