Indication of common faults
Each loop device has a unique address composed by the loop number and loop address. Installers can also
assign a text description to each loop device (i.e.: “MCP in the kitchenette”). In case a fault is processed for
any loop device, this information will be presented in the main screen and it will be added to the event log.
When a common device fault is reverted (i.e. a removed detector is connected again), the panel will clear
this fault indication and return to the quiescent functional condition. The event log will keep record of all faults
detected.
Figure 22: Fault Screen
Indication of faults affecting SND or FB outputs.
When a fault affecting the SND or FB outputs is detected, additional visual indicators “SND fault” and “FB
fault” will activate blinking to indicate that these functions have been compromised. See section 5.1.1.1 for
a description of the position of these LEDs.
SND and FB faults are unlatched and thus will be cleared automatically when the fault is resolved. The event
log will keep record of all faults detected.
Indication of earth faults.
The LCD screen will indicate if any of the system’s buses has an unintended contact with the building’s
electrical earth. Earth fault indications suggest a wiring defect. These shall be investigated and amended as
soon as possible by professionals.
Indication of system faults.
When a malfunction is detected in one of the panel’s core subsystems, it will be additionally indicated by
activating the “System fault LED” (See section 5.1.1.1). System fault indications are latched and will not be
cleared until the fire panel is manually reset, even if the function has been recovered.
System faults are not expected to appear during normal operation. The system should not be considered
reliable while it is indicating a system fault. Contact your maintenance company or technical support if a
system fault is present in your system.
