Checking the Exception/Subfault codes
'Exception' (EN) or 'Subfault' (BS) are condition codes and these codes provide information about a
sensor device. A code indicates small changes in the environmental condition, sensor mechanism
and how the sensor performs in the system. To ensure that the sensor exception codes are
meaningful, all existing codes must be cleared and the system left undisturbed for at least 24 hours.
Code definition
There are ten different conditions possible for each sensor type, although not all of them are defined.
Each condition code has a range of 0-3.
Code Meaning
0 This condition is OK. This code is not displayed unless another non
zero code exists.
1 or 2 Suggests preventive maintenance is required, where necessary, to
avoid possible false alarms.
3 The sensor is faulty. A fault condition indication is given at the control
panel. A message reading ‘Sensor Out of Specification’ is displayed.
A CODE 3 is automatically disabled by the system to prevent false alarms.
To view the exception/condition codes of a device
Press to select Menu On/Off button and select [Info] -> <etc> -> [Event] -> <etc> -> [Exception]
-> [Enter]. To view all the currently active exceptions on the system use the next and previous menu
options to scroll through.
# - will appear if a PIN is setup.
How to clear 'Exceptions'
This can be done by removal and replacement of the sensor chamber, by re-allocation of the loop
having the sensor or, by using [Clear] function at the panel:
Press Menu On/Off button to select [Test/Eng] -> [Usercode]# -> <etc> -> [Config] -> [Clear]->
[Exception] -> [Enter]. Note cleared codes will return if the conditions are still true.

1000000000or
0100000000or
1100000000
This is the sub-fire band and
if set as shown it should be
taken as showing that the
sensor is at its optimum
sensitivity for its location.
No action need be taken.
2000000000or
0200000000or
2200000000
A sub-fire has been
generated which would
suggest that the sensor was
either too sensitive for its
environment or that the
sensor type may be
incorrect for the location.
Action should be to check
location and alter sensor
state or type as required.
This should only be done
with the knowledge of the
customer. Remember to
re-backup all changes to
states onto the NVM.
0010000000or
0020000000
These codes indicate that
the sensor is in a windy
location. This will cause the
chamber voltage to drop.
Code Level 1 shows one
drop only, Level 2 shows
greater than one drop.
The location should be
checked and a change in
siting made, if required.
Note: Wind will not cause
the sensor to false alarm.
0000100000or
0000200000or
0000010000or
0000020000
This shows that the sensor
time averages are close to
acceptable limits.
On commissioning the
sensor should be replaced.
A sensor with code 2 is
worse than code 1. On
maintenance sensors with
code 2 should be replaced.
0000001000or
0000002000or
0000000100or
0000000200
This shows that high
frequency noise events have
been detected by the
system. A code 1 shows one
event and a code 2 shows
more than one event.
The device should be
replaced. On maintenance,
sensor with code 2 should
be replaced. If it reoccurs
then check the
environment.
0000000010or
0000000020
This shows device hardware
faults. 1-fault code 1 and
more than one fault code 2.
The sensor should be
replaced.
