Design Considerations
3.1
Main Power Supply Input
The FP-08450 Fire Control Panel provide a single power supply input that is compatible with
12 / 24vDC. If adequate power is not supplied, the LEDs will not be illuminated, and the
control panel will not operate. The main power supply should be connected directly to a battery
or power source, not through a distribution board. The main power must not be interrupted if
the vessel is powered down. The FirePro Battery Lead (P/N FP-14016) may be used to connect
power to the control panel.
The recommended configuration i
s to use the vessel’s emergency batteries, provided that the
vessel has an automatic changeover for its power supply.
3.2
Backup Power Supply Input
A secondary power supply is required for marine installations. Where the vessel’s emergency
batteries are not suitable, the control panel will need to be connected to a secondary power
supply or the FP-08870/08871 Power Control Module will be required.
The secondary power
supply should be connected directly to a battery or power source, not through a distribution
board. The secondary power supply must not be interrupted if the vessel or main power supply
is powered down.
Note: The secondary power supply must be the same voltage as the main
power source.
3.3
Siren/Strobe Output
A siren is required for all marine installations. The recommended siren/strobe is the Flashni
Xenon Sounder Beacon. In a typical install, the maximum number of supported sirens/strobes
that can be installed is 5. When installed, Siren/Strobes are to be clearly visible and audible
at all points around the risk area.
The siren/strobe output is a monitored circuit. The supplied end-of-line diode (1N4004) must
be installed on the last siren/strobe in the circuit, otherwise the fire control panel will display
a fault.
3.4
Discharge Output
The maximum number of FirePro generators able to be discharged by the FP-08450 Fire
Control Panel is limited by the voltage of the main power supply. That is:
Voltage 12vDC Max = 2 Units Voltage 24vDC Max = 4 Units
If a risk area requires a greater number of FirePro generators to be discharged than the
standard panel can provide, the FP-08850 Discharge Delay module can be used. The module
will discharge generators in multiples up to the maximum as above.
If the number of FirePro generators connected to each output is greater than the
maximum, the fire system will not operate.
When multiple FirePro generators are connected to a single output, they must be connected
using the FP-08919 Splitter Lead (see 3.9 Connecting Multiple FirePro Generators).
If a suppression system is not used, the supplied end-of-
line resistor (3k3Ω) must be connected
to the Discharge output using the supplied deutsch plugs.
