The LED/switch user interface consists of a variety of modules, mounted to the front of
an expansion bay, which are configured via the 4100U Programmer. Each display module
contains between 8 and 24 switches and LEDs, each one separately configurable.
User interface functionality is driven by the 64/64 LED/Switch Controller Card, which
mounts behind two of the display modules (in positions 1 and 2). The types of modules
typically used in 4100U-S1 are as follows:
• 4100-1288 LED/Switch Controller Card with mounting plate.
• 4100-1289 LED/Switch Controller Card (no mounting plate; it mounts on the
expansion space of 4100-1288).
• 4100-1282 Display Card. With one red and one yellow LED per switch, this is
used for Alarm Zone Facility displays.
• 4100-1294 Slide-In Label Kit - one per 4100U-S1 cabinet
• ME0456 Fan Control Module
Each 4100-1288 or 4100-1289 LED/switch controller supports up to 64 LED indicators
and 64 switch controls. Using the 4100-1282 Display Card for zone displays, this
corresponds to 32 zones per controller.
Other display cards are available for special display functions. Special configuration is
required to use other display cards. Contact your Simplex dealer for guidance.
