COMMISSIONING (continued)
Remote power supply
If required, the supply to the control panel can be derived from a remote power supply and battery
unit. Input terminals are provided in the control panel on the main pcb for the 28V supply, charger
and battery fault conditions. The clock and data lines must be maintained. For connections see the
Terminal Block 4 diagram .
In the event of remote supply failure the LCD shows 'Power Supply Fault'.
CPU reset
The 'CPU Reset' pushbutton on the main pcb is provided to manually restart the system following
the failure of the software to execute a command. The effect is the same as disconnecting and
reconnecting power to the panel.
Checking the system
Any fault conditions indicated at this stage should be investigated and cleared before putting the
system into operation.
Check that the system operates in accordance with the operation described in the following pages.
Clear SYSTEM FAULT
Following an incident where the panel failed to execute software or crashed during operation a
’SYSTEM FAULT ’ previously known as 'ARW' (Automatic Reset Warning) indication is present.
This must be cleared by operating the RESET switch on the front panel.
If SYSTEM FAULT warnings occur during normal system operation, there may be 'interference' or
a software problem. The source of the problem must be investigated. Contact the manufacturer for
further advice.
Operation of the control panel in the event of a system fault.
In the event of a system fault where the memory contents of a loop card may not be relied upon
the panel will enter a ‘safe’ state utilising a set of default parameters for that loop (unless the loop
is completely inoperable). In this case devices will report as belonging to zone 1 and in the case of
an alarm condition outputs will revert to a common fire operation (i.e. any special programmed
cause and effects will not apply). The device loop and address will be displayed in the event of a
fault or fire condition.
In the Fusion panel each loop or 4 way radial card is controlled by it’s own independent micro-
controller, so no more than 126 devices would be affected by a system fault on a single processor.
In the event of a system fault affecting the display PCB, fire events are indicated via a pure
hardware link which operates the ‘General Fire’ LED, panel buzzer and the four sounder circuits /
remote signal (if programmed)
Note
If sounder circuit 4 is ‘not’ programmed for use as ‘Fire alarm routing’ output
A diode ‘D53’ located above the supply healthy LED can be snipped from the PCB to prevent the
‘Fire alarm routing active’ LED being lit in the case of a Fire alarm whilst the display PCB is in
‘system fault’ condition. If sounder 4 is in use as a ‘Fire alarm routing output’ leave the diode D53
intact.
