FAULT CONDITIONS
When a fault occurs on a critical part of the fire alarm system, the panel responds by activating its internal
sounder and illuminating the general fault light and any other fault light(s) relating to the fault. The panel’s
fault output will also activate (provided it hasn’t been disabled). The type of faults typically indicated at the
fire alarm panel are described below:
CFP 2/4/8 ZONE CONVENTIONAL FIRE ALARM PANEL
CFP USER MANUAL • Approved Document No. DFU7001010 Rev 1 • Page 9 of 20
In the event of a fault condition:
• Mute the panel’s internal sounder by pressing the Silence Internal Sounder button (the panel does not
have to be in access level two to do this).
• Record the fault(s) in the Fire Alarm Log Book (page 14) and take appropriate action to correct it/them.
See User Responsibilities (page 5).
When a fault has been rectified the indicator light for that fault is automatically turned off. If all faults are
cleared, the general fault light will go out, and the panel’s internal sounder will be silent (if not already
muted). If the fire alarm panel is reset any existing fault(s) will reappear as before and the silencing process
will have to be repeated.
Zone Faults
The relevant zone fault light flashes when there is a wiring
problem on a zone or a detector has been removed from its base.
Note: Any alarms raised on the faulty zone(s) may not be
recognised by the fire alarm panel until the fault condition has
been cleared.
Power Supply Fault
Flashes when the mains supply
has failed, or the standby
batteries or its charger are
faulty.
If the mains supply fails, the
panel will only operate for the
standby period determined by
the size of the batteries fitted.
If the batteries or charger fail
at the same time as the mains,
the panel will not operate
.
Fault Output, Remote
Output or Auxiliary
Output Fault
The relevant light
flashes when there is a
fault on the relevant
output’s auxiliary 24V
supply.
System Fault
Flashes when the panel’s
microprocessor has reset,
typically after excessive
electrical interference, or if
the contents of its memory
have been corrupted. This
fault can only be cleared by
pressing the Control Panel
Reset button. If the fault
re-occurs within two
minutes, this indicates
corrupt memory and expert
advice should be sought.
Repeater Fault
(CFP model dependent
- see page 3)
Flashes when the
connection between
a repeater fire alarm
panel (if fitted) and
the master fire alarm
panel fails.
Depending on where
the fault has
occurred, some or all
of the repeaters may
not operate.
Sounder Status
Flashes when there is a
wiring fault on the
sounder circuits.
Depending on where
the fault has occurred,
one or all of the alarm
sounders may not
operate.
