Fault Condition - ABB Eurofire EN54 User And Engineers Instructions

Fault Condition

In a fault condition, the internal buzzer will sound and the 'GENERAL FAULT' LED will be illuminated.
LED's specific to the fault will be made flash. Devices connected to the fault relays will be triggered e.g.
digital communicator.
Eg. Shown below is a fault with the power supply and zones 1 & 4 are in fault also.
FAULT 1of 3
zone 1 Short Circuit
Last Fault =
Zn missing/open/EoL
Faults detected and displayed by the Eurofire are:-
- Zn X missing/open/EoL
Indicates that the zone X (1 to 16) is in fault with either a missing detector, a break in the wiring or
the End of Line device is missing.
- Zn X Short Circuit
Indicates that the zone X (1 to 16) has a short circuit on the wiring.
- Zn X Det Missing
Detected only on zones set as Two Wire. Indicates that a detector has been removed from zone X.
- Pnl X AL Y Short Circuit
Indicates that the panel at address X (1 to 32) has a short circuit on the Alarm Y (1 to 4) wiring.
- Pnl X EoL AL Y msng
Indicates that the panel at address X (1 to 32), Alarm Y (1 to 4) has either the End of Line device
missing or the wiring is open circuit.
- Mains Failed
Indicates that the 230V AC mains supply to the panel has become disconnected.
The fire panel installation will have the capability to run the fire alarm system for nominally
48 hours in the event of a mains failure. After this period, fire monitoring by the system will be
lost. The cause of failure will need investigating and rectifying to prevent loss of cover.
- Battery Missing
The standby battery system has become disconnected. The cause of failure will need investigating
and rectifying.
- Temp Sensor Fail
Indicates that the temperature sensor used as part of the battery charging has failed.
However, the battery is still charged, but at a nominal rate of 20
investigating and rectifying.
Line 1- - Shows which fault is being
displayed on line 2 and the total number
3
of faults detected.
Line 2- Alternates between the zone
number and details of the fault.
Using buttons 4&5 you can scroll and
display all faults individually on this line
Line 3- Shows the last fault to have
occurred – which is also the total number
of faults.
Line 4- Gives details of the last fault
showing the fault and zone number.
