Code Fault description
E 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.
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.
