How to clear Exception codes
This can be done by removal and replacement of the sensor chamber, by re-allocation of the loop having the sensor or
by using the menu controls.
Press Menu On/Off button.
a.
Select [Test/Eng] and then [Usercode].
b.
Select <etc> to display and select [Config].
c.
Select [Clear] and then select [Exception] and [Enter].
d.
"
All cleared codes will return if the conditions are still true.

Meaning
This is the sub-fire band and if set should be
taken as showing that the sensor is at its optimum
sensitivity for its location.
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.
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.
This shows that the sensor time averages are
close to acceptable limits.
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.
This shows sensor hardware faults. 1 for code 1
and more than one for a code 2.
This shows that transmission faults are being
noted. Code 2 is worse than code 1.
Action
No action need be taken.
Action should be to check location and
alter sensor state or type as required.
The customer should be made fully
aware of this change. Remember to
backup all changes of 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 sensor should be replaced. On
maintenance, sensor with code 2
should be replaced. If it reoccurs then
check the environment.
The sensor should be replaced.
The sensor should be replaced. If it
reoccurs then check the environment.
