A short circuit indication is caused by a loop component connected the wrong way or a short circuit in the wires. If

short circuit isolators are used, the shorted part of the loop between the closest isolators will be non-operative. By

scrolling trough the addresses list for the shorted loop and comparing with the installation plan, the shorted area

can be located. (If the panel is configured, it will indicate fault alarm for all addresses between the operated short

circuit isolators).

A break in the loop is easily found by disconnecting the return end of the loop and comparing the addresses that

the panel can communicate with, with the installation plan.

An earth fault can most easy be found by splitting the loop in two parts, disconnecting the return end of the loop

from the panel and restart. If the panel still indicates earth fault, the location is in the still connected part of the loop,

otherwise in the non-connected part. By splitting the faulty part of the loop in two and restarting again, you will soon

find the reason for the earth fault.

Fault and maintenance warnings of the loop devices are identified by codes in the display. The codes and a short

explanation of each are listed below.

Fault and maintenance warnings of address point

s = start up phase when scanning devices (after panel (re)start or when is loop connected by user)

The loop has to be re-scanned again after the reason of warning has been fixed.

r = running time when device is normally monitored

c = loop is configured with PC

n = loop is not configured

MAINTENANCE 00: (s,c)

− The anytype of device has been configured for this address but no device

is installed.

Indicated only once and will disappear after resetting the warning

MAINTENANCE 01: (s,c)

− No device has been configured to this address but some device is

installed.

Indicated only once and will disappear after resetting the warning

MAINTENANCE 02: (s,c)

− Definite type of device has been configured but no device is installed.

This warning can be removed only by installing device to this address or

changing the configuration and scanning the loop again.

MAINTENANCE 03: (s,c)

− The configured type/family and installed type/family is not the same or

protocols of devices are not same (types are.

This warning can be removed only by changing device to this address or

changing the configuration.

MAINTENANCE 04: (s,n)

− NA

MAINTENANCE 05: (s,n)

− Illegal address. For example address 0 found in the loop scanning phase.

− Factory setting of address switches are 0,0. The LED’s of the unit blinks

automatically for easier identification (when LED blink jumper is not

installed).

Note! It is not possible to detect any other fault or fire conditions for a unit

that has the 00 address.

FAULT 06: (s,c/n)

− Unknown type of device installed to the loop. The address is not polled

any more.

FAULT 07: (s,n)

− Device removed from this address during the loop disablement. The fault

is detected when the loop is re-enabled again.

Note! The panel has to be boot to clean up MC loop database

FAULT 08: (s,n)

− The type of device is changed during the loop disablement.

Note! The panel has to be boot to clean up MC loop database

FAULT 09: (s,c/n)

− New addresses (devices) are found in the loop.

Indicated only once and will disappear after resetting the warning
