Device not found during Loop Auto Learn

During the Loop Auto Learn process, the panel cannot communicate with a device that was previously programmed onto the loop. Auto Learn suspends and a pop-up prompts the engineer to keep or delete the missing device (individually, or all missing devices at once). If the device is kept, the panel reports a fault condition until it is reconnected; if deleted, all its prior programming (sensitivity, text, zone, action) is cleared.

Device flagged dirty during Loop Calibrate

Running Loop – Calibrate requests each loop device's internal drift/contamination value. If the value returned by a device exceeds a preset limit, the panel flags a "Dirty" fault against that specific device. The manual does not give the numeric threshold or a remedy; drift values can also be downloaded to the Service Tool.

Earth fault

An Earth Fault shown on the panel display. Whether the panel shows an Earth Fault during normal operation is set by the Earth Fault Notification parameter (manual section 3.3.18.7), toggled with the tick button.

Scheduled service date reached

The panel can hold a programmed "Service Due Date". When that date is reached, the panel enters a fault condition to alert the site operator that a service visit is overdue, and the status display shows the configured service telephone number whenever a fault condition is accepted. The fault clears automatically as soon as a new service due date is entered — no manual fault-clear step is described.

Device type does not match the type programmed at that address

During Loop Auto Learn, the panel finds a device of a different type fitted at an address than the type originally programmed there — the manual gives the example of a heat detector installed in place of an optical smoke detector. The engineer is prompted to accept or reject the new device type (individually, or all at once). Accepting reconfigures that address to the new device with initial default settings; rejecting keeps the original device's programming and the panel reports a fault condition until a device of the correct type is reconnected at that address.
