Fault records by panel

Reported as an ISOLATOR FAULT with a description. The manual says to use the same method to locate the break (re-run the loop search and check the detailed loop report). In its example, the break is between address 150,…

The manual says the panel's loop isolator monitors the addressable loop for open and short circuit faults, reported as ISOLATOR FAULTS with a description. For a break in the positive wire, it says to locate the cable…

If the panel reports a loop short on side A, the manual says there is a short circuit fault on the loop somewhere between the panel (side A) and the first device with a short circuit isolator on the loop.

If the panel reports a loop short on side B, the manual says there is a short circuit fault on the loop somewhere between the panel (side B) and the last device with a short circuit isolator on the loop.

The manual lists several reasons for the zone fault LED to light: a device has been removed from that zone; a device has been changed for one of a different type; there is a double address in the zone; or a device in…

Something is shorting to earth on the negative side. Located using the same method as an Earth Positive Fault, but looking for shorts to loop negative rather than positive.

Something is shorting to earth on the positive side (usually through a cable screen). Most earth faults occur on the addressable loop — disconnect all loop connections and reset the panel; if no earth fault is reported…

A system fault is an abnormal microprocessor running condition caused by various unexpected phenomena. The panel attempts to correct itself; while the fault is present the System Fault LED, General Fault LED, General…

The panel has measured the battery internal resistance and determined it is too high. The batteries will need to be replaced.

The panel has determined that the power supply is not charging the batteries. This is likely to be a problem with the Charger PCB — contact the supplier to arrange a replacement.

Two or more devices may have the same address setting. All devices with the same address will answer at the same time and the panel will not be able to understand the reply it receives. Search the detailed loop report…

Check if mains power is present, and check for 29.5V DC at the PSU cage output.
