The
MX1
provides a number of options for interfacing to fire brigade
Alarm Routing Equipment (alarm signalling equipment).
J12 - Integrated relays and ELD resistors for signalling alarm,
fault, and disable to the FAS input of a Centaur ASE. Note that the
Centaur ASE resistor network FP0740 ELD device is not required.
Clean contact changeover relay for each of alarm, fault and
disable on J9, J10 and J11 respectively.
SGD interface on J8 provides power and alarm and fault signals to
a compatible SGD. Currently no suitable devices are available for
use in Australia.
The routing signals on the J8 SGD interface, J12 Centaur
ASE interface and the J9, J10, and J11 relays operate
together. They cannot be used independently.
If the J8 SGD interface, J12 Centaur ASE interface and the J9, J10 and
J11 relays are not required for alarm and fault routing equipment, the
relays can be used as general purpose unsupervised relay outputs by
suitably programming the site-specific configuration.
Up to eight Remote Display Units or Alarm Display Units (Nurse Station
Annunciator or Compact FF) can be connected to the RZDU interface on
the MX1. Other RZDU protocol devices (e.g. T-Gen2, IO-NET or QE90
EWIS) can also be connected to the MX1 via the RZDU bus.
RZDU devices that are separately powered should not be connected to
the +VRZDU line, but must be connected to the 0V line.
The TXRZDU and RXRZDU signals m
ust “cross-over” between the MX1
panel and the first RZDU device, as shown in Figure 11-18A. There
must not be any wiring crossover between subsequent RZDU devices.
Wiring between RZDU devices can be a daisy chain or a star format.
The cable can be a single four core type or a pair of twin core types.
If a Master T-Gen2 is added this changes the wiring arrangement.
The Master T-Gen2 is connected to the RZDU bus as the first device
using the FP1143 High Level Interface (HLI) board. All field RZDU
devices along with other RZDU protocol devices such as IO-NET
controllers must be connected to the RZDU Field connection (J4) on the
HLI board.
Power +V and 0V is to be connected from the
MX1
to the RZDU FIP
connection on the FP1143 HLI Module. The TX and RX signals must
“cross-over” between the MX1 panel and the HLI Module. The RZDU
FIELD connection to the first RZDU device must cross-over too, as
shown in Figure 11-18B. The FP1143 HLI Module is connected to the T-
Gen2 using a 10-way ribbon cable from J2 of the HLI board to J29 on the
T-Gen2.
