The rules on this page apply exclusively to MINIPLEX systems. Review each guideline
before installing a MINIPLEX 4100U system.
• All wiring is 18 AWG (0.8231 mm
2
) (minimum) and 12 AWG (3.309 mm
2
)
(maximum).
• All wiring is supervised and power-limited.
• All wiring that leaves the building requires overvoltage protection. Install
module
inside an UL-Listed electrical box wherever wire enters or exits the building. A
maximum of four 2081-9044 Modules may be connected to one channel. The
2081-9044 is rated for 200 mA (maximum).
• AS1670 allows the loss of a maximum of 40 detectors/addressable devices to be
caused by a single fault.
• For Style 4 operation:
- The maximum distance to any device is 2,500 feet (762 m).
- “T” taps are allowed.
- The total maximum distance (including all “T” taps) is 10,000 feet (3,048 m).
- Maximum allowed line-to-line capacitance (“+” to “-” terminals) is 0.58 uF.
For applications with shielded wire, be sure that the total capacitance from line
to line plus the shield to either line is no more than 0.58 uF.
• For Style 6 or Style 7 operation, the maximum loop distance is 2,500 feet (762
m). “T” taps are not allowed.
• RUI comms are wired to remote cabinets from the CPU motherboard to one of
the following transponder interface cards: 4100-0620 (566-093) or 4100-0625
(566-094).
• Annunciators and transponder interface cards support Style 7 operation when the
system is wired Class A.
• The master control panel must be a 4100U Fire Alarm Control Panel.
• The Style 4 RUI card supports MINIPLEX transponders and 4602/4603 serial
annunciators on the same signaling line circuit.
• Up to 4 RUI cards in the 4100U Control Panel can be used for distributing
transponder wiring in different directions or for supporting different wiring
requirements (such as using a Style 7 RUI for serial annunciators).
• Up to 31 transponders can be controlled from the 4100U Control Panel, and can be
distributed as required among the RUI cards.
