Suitable cabinets for Mimic Displays include:
ME0073 PICTURE FRAME DISPLAY,F/S, EMPTY,003 LOCK,C/W INDEX
ME0074 PICTURE FRAME DISPLAY,F/S,EMPTY,60124 LOCK,C/W INDEX
ME0076 PICTURE FRAME DISPLAY,R/S,EMPTY,60124 LOCK,C/W INDEX
or various FP1600/OMEGA 64 empty cabinets and the PA0787 FP1600 Mimic Display
Board provide an alternative format.
At the display panel there are two possibilities:
(i) Geographic Plan Mimic - the FRCs from the NDU are connected to Termination
boards (PA0483). Individual LEDs with series resistors are mounted on the display
panel and wired to these Termination boards. Figure 12.8.1 shows this arrangement.
Alternatively, the PA0769 Termination Board has 3k3 resistors already fitted (gives
7mA LED current which is adequate for interior use).
(ii) Column Format - where arrangement of zone alarms into columns is acceptable,
LED Mimic Display boards can be used. This simplifies the wiring considerably.
The Picture Frame Display (ME0074 or ME0073 Front Service, or ME0076 Rear
Service) is a suitable cabinet, and also has mounting hardware for four 16 zone
Display mimic boards (PA0753), plus one Common Indicator and Index Lamp Mimic
board (PA0760). Figure 12.8.2 shows this arrangement.
Note that a special 3-way FRC is required for the Display Extender board, so that the
miscellaneous inputs are accessible in the NDU cabinet. This is not a standard part,
and will need to be made up to suit the application.
12.8.3 ACTIVE DISPLAY
An active display is driven from the NDU display chain and is economical for large mimics.
The Picture Frame Display (PFD) cabinet is suitable for housing an active display with a 12
way shielded cable linking it to the NDU (ref. Figures 12.8.3 and 12.8.4). No supervision
requirements for this cable are specified in NZS 4512, but because some individual wires in
the cable are not supervised (though the cable as a whole is), good fire alarm practice
dictates that the distance between the panel and indicating unit should be limited for
principal brigade mimics. The wiring should also be well protected by conduit, trunking or
equivalent. An electrical limit of 30 metres applies to this connection.
The following parts are available for constructing displays of this type:
PA0742 PFD NZ DISPLAY EXTENDER BOARD,24V
PA0741 PFD DISPLAY 16 ALARM LED,24V (ALARM LEDS ONLY)
PA0754 PFD 16 ZONE,FULL STATUS,24V (ALL LEDS)
FP0646 16 ZONE ALARM KIT (PA0741,FRC LOOM,POWER LEADS)
