6.4 Fault Messages

6.4.1 Channel Faults

Vortex is able to detect and display faults relating to common problems in both gas and fire

detectors.

On the Display Module, these faults are displayed as codes in the Reading display.

Table 17: List of channel faults

Code Fault description

This is displayed when a fault is clearing. It is replaced by

the normal reading in a few seconds.

E001

Channel Access fault. A problem with the communications

between the Node Controller Module and Quad Channel

Input Module has occurred.

Check that all Quad Channel Input Modules are configured

with the correct addresses.

E002

All inputs disabled. Restore inputs in accordance with the

system specification before leaving the system in normal

operation.

E006 Under Range fault (Open circuit). The current has fallen

below 1mA for gas detector inputs, and less than the open

circuit level for fire inputs.

Check for open-circuit or wiring faults that cause

abnormally low loop currents in detector wiring.

E007 Over Range signal (Short circuit). The current is greater

than 23.5mA for gas detector inputs and greater than the

programmed short circuit value for fire inputs.

Check for short-circuit or wiring faults that cause

abnormally high loop currents in detector wiring.

Assume a high level of gas is present at the detector.

E008 Zero fault. This occurs only in Channel Test mode (section

7.4). The input is too far from 4mA to allow compensation.

The input must be between 3.5 and 4.5mA. Check the

detector output with a meter.

E009 Scale fault. This occurs only in Channel Test mode

(section 7.4).The input is too far from the expected value

to allow scale compensation. Check the detector output

with a meter. Check that the detector has been calibrated

correctly and the correct range has been configured.
