The 4-digit display on the UI panel is used to indicate detailed fault information in case the general
FAULT LED is on. The 4-digit display will start blinking when multiple faults are present. When
scrolling through the faults, it will stop blinking until 30s achter the last button press.
In case of a standalone system the first two digits of the display are not used and the fault code is
displayed as a 2 digit code (XX) only. The disabled codes will stay the same, regardless of
standalone or connected (ddXX).
In case of connected systems the fault code is shown as a 4 digit code (N-XX), where
- N = the system number (0 to 7; 0 for Master system, 1-7 for Slave system)
- - = dash sign (-)
- XX = a 2-digit fault code as described in Table 19
In case of a disablement function the following codes can be shown:
- dd11 = Gas release disabled
- dd22 = Manual Activation Button (MAB) disabled
- dd33 = Smoke sensors disabled
The Master system shows all fault codes of all connected systems. A Slave system shows the fault
codes of that slave system only.
Examples:
1. For a standalone system that has a mains power fault the UI panel will look like this:
