9.2.4 Power Supply Problems
Fault Description Solution
BATTERY FAULT
xxx
Battery not present or Battery volts
low
Note: This indication should be expected
during recharge -after a mains failure.
BAT LOAD FAIL Battery Load Test has failed Only displays if option selected. Battery
uncharged or capacity below specification –
then it may need replacing.
BAT CRITICAL Battery being disconnected Protects the battery from deep discharge
damage during extended mains failure.
Note: The system is about to be powered
down!
MAINS FAIL xxx Mains supply failed System detects that the mains frequency is
out of specification, as well as voltage. Note:
‘AC FAIL’ timer operative
LOW VOLTS xxx Power supply volts low Battery volts below normal ‘battery fault’
level during a mains failure
9.2.5 Engineer Indications
Fault Description Solution
Engineer Access
Denied
Access to Engineer menu NOT
possible, as system is not fully
disarmed.
Ensure that ALL areas are disarmed, using
suitable user codes / tags at the appropriate
keypads / readers.
Check Failed Input
xxx
Input in fault on attempting to exit
Engineer mode.
Applies to 24-hour tamper, or other input
types that would generate an alarm condition
if the system were returned to disarmed
mode. This also applies to tamper faults on
other input types. Check for the fault on
input, or omit it in programming.
Error input Areas
not accessible
An input has been programmed to
an area for which no arming point is
valid to disarm.
It would therefore be impossible to fully
disarm the system after a tamper alarm on
that input. Programming must be adjusted
before exiting Engineer mode.
Error some Areas
cannot be
disarmed
Arming points have been
programmed so it's possible to arm
an area, but not disarm it.
Programming must be adjusted before
exiting Engineer mode.
