RDU
8.1.1 CABINET INSTALLATION
The location of the RDU is chosen by the Fire Authority and building owner (or owner's
representative) in accordance with the appropriate installation standard.
The cabinet is normally fixed to a wall with four 6 mm screws or bolts. The drilling details are
shown in Figure 8.1.1 for the 15U cabinet, in Figure 8.1.2 for the slim line RDU, and in
Figure 8.1.3 for the flush mounting version.
The following conditions are required:
1.
Dry Area.
2.
Moderate ambient temperature, 45°C absolute maximum.
3.
Not exposed to direct sunlight.
4.
Not subject to outdoor conditions without suitable protection.
5.
The LCD should be at average eye level and must not be higher than 1850 mm or
lower than 750 mm above finished floor level.
6.
Clear access and viewing for Fire-Fighters and operators.
7.
At least 1 metre free space should be provided in front of and on sides of the RDU for
installation and maintenance.
8.
Must not be installed in hazardous areas as defined in AS3000.
9.
If recessed into a wall:
i. Allow for the door to open at least 145°.
ii. Prevent water entering the cabinet - seal unused knockouts and any top cable
entries. Preferably use bottom cable entry, with cables going down 100 mm
below cabinet before rising.
It should not be necessary to drill within the cabinet, but if drilling or filing is
required, remove the PCBs first. Clean out all swarf before replacing the PCBs.
Use antistatic precautions when handling the PCBs.
