Morley-IAS DX Connexion fault codes

Fault with the auxiliary supply

A fault with the auxiliary supply has been detected. Check the Aux voltage and any associated wiring.

Persistent communication errors with a loop/peripheral device

Persistent communication errors have occurred when communicating with a specific loop/peripheral device.

Integral battery charger has failed

The integral battery charger has failed and is not charging the batteries. Check that the thermistor flying leads are correctly connected.

Battery voltage at absolute low level

The battery voltage is at an absolute low level — check the battery.

Battery voltage unusually low

The battery voltage is unusually low — check the battery.

Battery presence cannot be detected

The presence of a battery cannot be detected.

Possible battery wiring connection fault

Continual checking of the battery has identified a possible wiring connection fault. Check connections to the batteries — may also indicate the batteries need replacement.

Configuration settings corruption detected

Some form of corruption has been detected within the configuration settings — this can occur following a software upgrade if the memory is not 'wiped'. Try wiping the memory or re-configuring from the configuration tool to clear the fault (followed by a reset); alternatively the base-card PCB must be returned to the factory.

Panel has been reset

The control panel has been reset — either by complete removal of power to the panel, pressing the reset button (top left of the base-card PCB), or automatically by on-board watchdog circuitry.

Detection device returning a very low analogue value

Generated if an analogue detection device is returning a very low analogue value. Check/replace the device.

Unrecognised or unsupported loop device detected

An unrecognised/unsupported loop device has been detected.

Wiring fault detected to earth

A wiring fault has been detected to earth. The fault can be narrowed down by systematically disconnecting field wiring, monitoring the earth fault reading and the voltage between battery negative and earth, or by repeatedly resetting and waiting 100 seconds each time.

On-board communications to the loop driver have failed

On-board communications to the loop driver have failed. Ensure the loop driver has been properly programmed; attempt to re-flash the loop drivers from the set-up menu.

Open-circuit wiring fault on an addressable loop

Open-circuit wiring fault detected on an addressable loop — check loop wiring.

Short-circuit wiring fault on an addressable loop

Short-circuit wiring fault detected on an addressable loop — check loop wiring.

Mains supply unusually low

The primary power supply (mains) is unusually low. Check mains voltage.

Configuration memory lock jumper missing

The configuration memory lock jumper (top left of the base-card PCB) has been detected missing from the locked position.

Mains power failed or removed

The primary power supply (mains) has failed or been removed.

Power Supply Unit module has failed

The Power Supply Unit module has failed. Replace the PSU module.

Program memory corruption detected

Continual internal checking of the program memory has found some corruption. The base-card PCB should be re-programmed or returned to the factory.

Wiring fault on a sounder output circuit

This indicates a fault with one or more of the sounder outputs. Correct the fault condition and then perform a panel reset.

Problem with the power supply, battery or supply input

There is a problem with the power supply, battery or supply input. Correct the fault condition and then perform a panel reset. The user manual lists five possible conditions under this LED: NO MAINS SUPPLY, BATTERY LOW, BATTERY DISCHARGED, BATTERY MISSING and CHARGER FAILURE.

CPU reset or system fault

The CPU has reset or a system fault has occurred. Correct the problem, if appropriate, and then perform a panel reset.

Configured Zone Fire LED PCB not connected

A Zone Fire LED PCB is not connected but is included in the configuration. Change the configuration or fit the PCB.
