Errors and faults

Communication BUS (I-BUS)
The control panel monitors the I-BUS continuously.
If no signals (control panel and peripheral signals) are detected on the I-BUS for over
40 seconds, the keypad displays will show the warning opposite. The display will show:
1. Keypad model
2. Keypad firmware version
3. Error type
4. Keypad address and built-in reader address (Joy/MAX only)
First check that cable “D” of the I-BUS is connected properly. Then check the proper
operating capacity of the I-BUS and the general integrity of the entire system.
If the message opposite appears on the keypad display, it means that I-BUS is
operating properly but cannot communicate with the keypad in question.
Therefore, the keypad is not present in the system configuration.
Note
One of the two messages shown in the figures may also appear during the control panel firmware
updates.
If you are using an Alien user interface, the above-mentioned information will be shown
on the bottom bar on the home page.

LED activity
The blue and yellow LEDs on the control panel motherboard (refer to
Table 4: Control
panels - description of parts, X
) may help in providing information regarding the proper
operating capacity of the control panel firmware and I-BUS, as follows.
Blue LED
If the control panel is operating properly, the blue LED on the motherboard will blink
rapidly. At the end of a programming session via PC, during restoral of factory default
settings and during re-programming operations on the control panel and peripheral
firmware, the LED may be either On solid or Off or the entire time. However, once the
operation is complete it will start to blink again as previously described.
If the LED is On or Off permanently for no apparent reason (see above), it means that
all the system functions are blocked.
Shut the system down and contact your dealer immediately.
Yellow LED
If the control panel is operating properly, the yellow LED on the motherboard should
flicker. At the end of a programming session via PC, during restoral of factory default
settings and during re-programming operations on the control panel and peripheral
firmware, the LED may be either On solid or Off or the entire time. However, once the
operation is complete it will start to blink again as previously described.
If the yellow LED is On or Off permanently, it means that there is trouble on the I-BUS.
If the LED is On or Off permanently for no apparent reason (see above), it means that
the I-BUS is blocked. This condition is confirmed by the loss of communication with the
keypads, readers and expansions.
Faults on IVY-BUS
sounderflasher
Sounder faults / Horn fault
A defect/damage has been detected on the
horn/sounder.
Press
on “Sounder faults” to
access the list of devices which
have at least one fault present.
Press
on the selected soun-
derflasher to access the list of
current faults on the device con-
cerned.
Sounderflasher faults / Low-
Batt.Soundfl.
A low-voltage value has been detected on the
sounderflasher battery.
If the voltage drops below 10V, the device will
inhibit the sounder and activate only the flasher
(in the event of an alarm). If the voltage drops
below 8V, the device will inhibit both the sounder
and the flasher.
Sounderflasher Faults / Battery
resist.
An excessive internal resistance has been
detected on the sounderflasher battery. This
type of deep fault indicates corrosion inside the
battery, therefore, the battery must be replaced.
Violation of zones with
faults
Faults on zones
Violation has occurred on one or more zones
with the “Fault zone” option enabled.
Press
to access the list of
zones involved.
Contaminated smoke
sensor
Detector dusty
The smoke chamber of at least one of the Air2-
FD100 smoke detectors is contaminated by dirt
or dust.
Refer to the instructions supplied with the detec-
tor for information regarding the respective
threshold.
