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 the:
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.

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. However, at the end of a programming session via keypad or PC, or
during restoral of default settings or re-programming operations, the LED may be
either On solid or Off. It will blink rapidly once the operation is completed.
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. However, at the end of a programming session via keypad or PC, or
during restoral of default settings or re-programming operations, the LED may be
either On solid or Off. It will blink rapidly once the operation is completed.
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.
Check the integrity of the I-BUS line.
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
sounderflasher to access the list
of current faults on the device
concerned.
Sounderflasher faults
/ LowBatt.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.
