Rectification process
Check all batteries are inserted correctly. Check voltage on
batteries. Replace batteries if necessary or re-insert correctly.
Check the mains supply to the unit.
It is recommended that the detection device be replaced due to
a fault with the head being reported.
Clean with compressed air if necessary, as the device is
reporting that the chamber is dirty. Check the device is in a
clean environment and is free from smoke, dust and dirt.
Check the device is assembled correctly.
Check the 20 kΩ end of line resistor is in place and that
connections are secure.
Check the devices location to ensure no visible cause can be
seen. Check that the device is still powered and has been added
to the system. (See the 'How to improve device signal levels'
section for more information).
Replace all device batteries with specified batteries - see the
associated device installation guide and replace within 30 days.
Check the integrity of the battery and it's connection.
Note: no fault will be indicated as communication is still taking
place, albeit at a low signal level. Check the device's location to
ensure there is no obvious cause. (See the 'How to improve
device signal levels' section for more information).
No action required.
Check the device's resettable element is correctly in place and
that the yellow area is not being displayed. If shown, reset the
device using the reset key.
Ensure that the environment in the device's location is free of
smoke, residue and dust.
