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.

Action
No action need be taken.
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.
The location should be
checked and a change in
siting made, if required.
Note: Wind will not cause
the sensor to false alarm.
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.
The device should be
replaced. On maintenance,
sensor with code 2 should
be replaced. If it reoccurs
then check the
environment.
The sensor should be
replaced.
