Beam Maintenance
Press enter to go into the ‘Beam Maintenance’ menu and access the sub
menus.
Dirt Comp
- This screen shows how much the beam has compensated
for dust build-up on the beam head and reflectors, ALWAYS take a note
of this value as part of your routine maintenance to see any build-up
pattern. If you see figures above +50% you should clean both the lens
face and the reflectors (once cleaned, you should instigate an auto
alignment to re-calibrate the beams settings).
It is possible that you may see a negative number here, this can happen
when the FIREbeam Xtra has been commissioned in a ‘dirty’ atmosphere
such as builders’ dust which, once cleared, the beam then compensates
for. To reset, perform an auto alignment to re-calibrate the beam. Press
enter to return to ‘Beam Maintenance’ or down to go to ‘Alarm & Fault
Event Counts’.
Alarm & Fault Event Counts
- Here we can see how many times the
beam has gone into fire or fault since the beam was commissioned or
since the event log was last cleared, including testing.
Press enter to clear events.
Press left / back to return to ‘Beam Maintenance’ or down to go to ‘Self
Test’.
Self Test
Press enter to perform a fire test, this works by running a test algorithm to
lower the output power, the receiver sees this as obscuration. When the
received signal drops below the threshold point the beam will trip the fire
relay – this relay will not trip until the time to fire has passed which could
be anything between 2 and 30 seconds.
Press left / back to end test, the fire test should show on the panel. Press
left / back to return to beam maintenance or down to go to ‘On/Off’.
On/Off
If something needs to be maintained in the beam path use the right and
left keys to turn the system on and off. This will show as a fault on the
panel. Press enter to return to ‘Beam Maintenance’.
