L748 Corridor LED Display Unit.
The L748 Corridor LED Display is ideal for where calls need to be easily and clearly seen by staff on the move. It may
be used in several applications including hospitals, doctors’ surgeries and larger nursing homes. Call information is
very clearly displayed on the illuminated 16 character display. The integral alarm is adjustable for day and night
volumes The display may be configured to show a standing message or appear “off” when no calls are active on the
system.
The unit is compatible with the INTERCALL 700 protocol only and shows the same text as the LCD display units.
The unit can either operate as the only type of display on the system or can be used in conjunction with the standard
LCD units. Operation of the unit is similar to the standard LCD units, with all calls numbered in queue order.
Emergency and Attack calls are “flashed” on the display to show the higher priority while normal, assistance and
priority calls are stored in memory but not displayed until the higher priority calls are dealt with. There are no user
controls on the unit, however, the display menus controls are available and the unit has a unique display menu structure
for configuration. These menus are configured using the two buttons in a similar manor to the standard display. For
more information on the L748 Display Menus, please refer to page 61
