The MINIPLEX version of the 4100 Fire Alarm System, which is designed for
moderately larger applications than the standalone configuration, allows up to 1000
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
optionally 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
4100U:
• 4100U: Transponder interface cards (TICs), located in transponder cabinets, take
the RUI data 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 optionally 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.
The MINIPLEX 4100 FACP must contain the following:
• CPU
• System Power Supply for the 4100U (Universal Power Supply for the 4100)
• 4100 only (non-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.
