Chapter 1 Introduction to the 4100ES Fire Alarm System
MINIPLEX configuration
Overview The MINIPLEX version of the 4100ES Fire Alarm System, which is designed for moderately
larger applications than the standalone configuration, allows up to 2000 monitor and/or control
points and 2000 annunciator points to be controlled by a single FACP.
Like the standalone system, only one CPU is used. Remote Unit Interface (RUI) data and
power is distributed from the host panel to remote boxes called transponder cabinets. The exact
system design varies, depending on whether the system is a 4100 or a 4100ES:
• 4100ES: Transponder interface cards (TICs), located in transponder cabinets, take the RUI
data and power directly from the CPU motherboard and distribute it to modules nearby,
thereby expanding the system’s status from standalone to MINIPLEX.
• 4100: Remote interface cards (RICs), located in transponder cabinets, take the RUI data
and power from the remote unit interface (RUI) card in the host panel and distribute it to
modules nearby, thereby expanding the system’s status from standalone to MINIPLEX.
System design The MINIPLEX 4100ES FACP must contain the following:
•CPU
• System Power Supply for the 4100ES (Universal Power Supply for 4100 Legacy Upgrade)
• 4100 only (non-4100ES/4100U): Remote unit interface (RUI) Card
• Optional slave cards
Each transponder cabinet, meanwhile, must contain a Transponder Interface Card (TIC) and
any number of optional slave cards.
