Does the „status LED" of the Purging unit illuminate green?
Connection of the compressed-air supply:
Make sure that the „status LED" of the Purging unit illuminates green and no fault can exist on
the fault input of the Purging unit.
Make sure that the compressed air and particles flowing out from the aspiration holes and the
check valve can not cause any damage.
Turn on the compressed-air supply to the Purging unit slowly, so that the pressure can build up
slowly.
Carrying out manual cleaning processes:
Carry out some manual Purging processes by electrically connecting the terminals 11 and 12
(input „Manual activation") briefly in order to gently remove possible contaminations in the
pipe network. Start with very short impulses (with a maximum duration of 1 second) and slowly
increase the time from impulse to impulse until the piping is completely filled with pressure and
a continuous Purging process is achieved.
Turn off the compressed-air supply to the Purging unit.
Carry out another manual Purging process in order to relieve the residual pressure in the system.
Connection of the aspirating smoke detector:
Connect the pipe between the aspirating smoke detector and the Purging unit.
If you have temporarily, for the time of commissioning, connected a 5.6kOhm resistor – instead
of the aspirating smoke detector – to the fault input of the Purging unit, remove the resistor and
properly connect the aspirating smoke detector.
Commission the aspirating smoke detector according to the information provided by its manu-
facturer.
Parameterisation:
On the Purging unit, set the time, the device number – if applicable, as well as the Purging pro-
gram.
Does the „status LED" of the Purging unit illuminate green?
Carrying out the Purging process:
Turn on the compressed-air supply to the Purging unit slowly, so that the pressure can build up
slowly.
Simulate a fault of the aspirating smoke detector (the „status LED" of the Purging unit is blink-
ing yellow).
Check whether the Purging process is carried out properly (the switching of the valve as well as
the flow of the compressed air are clearly audible – the „status LED" of the Purging unit altern-
ately illuminates red and green as long as the solenoid valve is activated).
Check whether the fault that still exists is transmitted to the fire detection control panel and is
correctly indicated there after the Purging process has been carried out (one minute after com-
pletion of the Purging process, the „status LED" of the Purging unit will change from blinking
yellow to illuminated yellow and the fault will be transmitted to the fire detection control
panel).
Terminate the fault condition of the aspirating smoke detector.
After that, is the fault automatically reset again on the fire detection control panel?
Only after checking whether the fault has been transmitted will it be ensured that the indication
of the fault of the aspirating smoke detector has been properly carried out right up to the fire
detection control panel.
Showing the user what to do:
Inform the user about possible limitations and dangers of the operation of the Purging unit and
train the user in the proper handling as well as the correct use and operation of the unit.
