PMM800 Power Monitoring
Module
Input
– The 230
V AC mains supply is connected to the
input of the power supply unit (BAQ60T24). The
28.6
VDC output from the power supply unit is fed to
the input of the PMM800.
Output
Table
7 shows the 3 DC output rails voltage ranges:
The PMM800 provides four 24
V outputs. Each output is
fitted with fuse. These are F1AL 250VAC 20x5mm fast
blow glass fuses.
There is a battery fuse fitted. This is a T8AH 250VAC
20x5
mm ceramic anti-surge fuse.
2.4.7
Siting Considerations
The fastenings are not included in the kit, so they will need
to be externally sourced. When specifying the fastenings
(such as the screw size), take into account the type of wall
and the weight of the assembled housing. The size of the
batteries will have a large bearing on the weight of the units
(see 2.4 “Collected Specifications” on page
The control panel is designed for wall mounting. Typically
screws and rawlplugs in drilled holes will be used. The
screw hole positions are shown in Fig. 1: “Overall and Fixing
Dimensions – FireClass Lite” on page
.
2.4.8
Environmental Stipulations
The control panel is not weatherproof. Check that the loca-
tion is indoors, dry and free from excessive dust. Also check
that location fulfils the temperature and humidity stipula-
tions shown in Table 8: “Temperature and Humidity Stipu-
lations”.
2.4.9
EMC
Product family standard EN50130-4 in respect of Con-
ducted Disturbances, Radiated Immunity, Electrostatic Dis-
charge, Fast Transients and Slow High Energy
EN 61000-6-3 for Emissions.

Component Module
Descriptions
The following sections detail the standard modules fitted to
an FireClass Lite control panel or repeater.
2.5.1
Central Processing Unit
The Central Processing Unit (CPU800 board) contains the
main processor and memory. It is mounted to the FIM801
Lite board.
2.5.2
Field Interface Module (FIM)
The FIM801 Lite provides all the inputs and outputs of the
control panel. Refer to Fig

(I(28)) in either condition, may be calculated from
the following formula:-
I(28)=I(max)-0.211*I(5)-1.568*I(40)
