The rules on this page apply exclusively to MINIPLEX systems. Review each guideline
before installing a MINIPLEX 4100ES system.
All wiring is between 0.75mm
2
(minimum) and 2.5mm
2
(maximum).
All wiring is supervised and power-limited.
All wiring that leaves the building requires overvoltage protection. Install the
protection module inside an electrical box wherever the wiring enters or leaves
the building. A maximum of four 2081-9044 protection modules may be
connected to one RUI channel. The 2081-9044 is rated for 200mA (maximum).
AS 1670 allows no more than 40 detectors/addressable devices to be lost by a
single fault. This is particularly relevant for Class B (spur) configurations.
For Class B (spur) operation:
- The maximum direct cable distance from the host panel to any transponder is
760m.
- “T” spurs are allowed.
- The sum of all the cable lengths (including all “T” spurs) must be less than
3,000m.
- 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 (this is usually only a
problem when using MIMS cables).
For Class A (loop) operation, the maximum cable distance around the loop is
760m. “T” spurs are not allowed.
Annunciators and transponder interface cards support loop operation when the
system is wired Class A.
The master control panel must be a 4100ES Fire Alarm Control Panel.
Up to 4 RUI cards in the 4100ES Control Panel can be used for distributing
transponder wiring in different directions or for supporting different wiring
requirements (such as using a Style 7 (Class A) RUI for serial annunciators).
Up to a total of 31 transponders can be controlled from the 4100ES Control Panel,
and can be distributed as required among the RUI cards.
