11.0 Fault Analysis Mode

If a fault occurs, the FAULT or MAINS indicators
flash and the codepad beeps once every minute.
11.1

AC Fail

If the AC mains supply fails, the MAINS indicator
flashes until the AC mains supply is restored.
Pressing [#] once acknowledges the fault and stops
the codepad from beeping once every minute.
11.2

System Faults

To determine all system faults other than the AC
mains supply, enter Fault Analysis Mode:
1. Hold down [5] until two beeps sound.
The FAULT indicator lights steadily and the
STAY and AWAY indicators flash in unison.
Any lit zone indicators indicate the type of fault
that occurred. See Table 9 for the list of system
faults that can occur.
2. To further determine the type of fault condition,
hold down the key that corresponds to the lit
zone indicator.
3. To exit Fault Analysis Mode and return to the
disarmed state, press [#].
The FAULT indicator remains lit and the
codepad stops beeping once per minute.

Table 9: Fault Condition Indicators
Zone LED FAULT Condition
1 Battery Fail
2 Date/Time
3 Sensor Watch
4 Horn Speaker Fail
5 Telephone Line Fail

7 Fuse Fail
8 Communication Fail
Battery Fail
A battery fail fault registers when the system detects a
low capacity backup battery. The system
automatically performs a Battery Test every 4 hours
and every time the system is armed.
Date and Time
The date and time fault registers every time the
system powers down. This type of fault does not
cause the FAULT indicator to display on the
codepad unless your installer programmed the
automatic arming time. Refer to Section 10.0 Setting
the Date and Time to program the date and time.

Sensor Watch Fail
A sensor watch fault registers because one or more
detection devices failed to notice any movement
during the disarmed state for the time period
programmed by your installer. The fault clears when
the zone in question detects movement and is reset.
While in Fault Analysis Mode, hold down [5] until
two beeps sound.
The indicator corresponding to the faulted zone
lights.
Horn Speaker Fail
A horn speaker failure fault registers when the system
detects the horn speaker is disconnected. This fault
clears once the horn speaker is reconnected. Your
installer must program the system for this feature to
operate.
Telephone Line Fail
A telephone line failure fault registers when the
system detects the telephone line is disconnected
from the control panel. Your installer must program
the system for this feature to operate.
E2 Fault
An E2 failure fault registers when the system detects
an internal checksum error. Contact your installer if
this fault occurs.
Fuse Fail
A fuse failure fault occurs when either of the two 1 A
fuses are blown. Contact your installer if this fault
occurs.
Communication Fail
A communication fail fault registers when the control
panel fails to communicate with the receiving party
(for example, a monitoring company, mobile phone,
pocket pager, and so on). The communication fault
clears after the control panel successfully reports to
the receiving party.
