Key Points
1
Detectors that require maintenance / commissioning should be taken off
line and inhibited. Detectors which require to be opened will need to be
isolated electrically.
Ensure that panel wiring
and terminations
associated with all units
under test are in good
order.
2
Ensure that the detector mounting arrangements are secure and
undamaged.
3
Ensure that the detector enclosure is intact and undamaged.
4
Ensure that all associated cables and glands are correctly made up, secure
and undamaged.
5
Clean the enclosure faceplate (outside) with a mild detergent solution and
a soft cloth until the window is clear of all contamination. Wash the
window thoroughly with clean water and dry with a clean lint free cloth or
tissue.
Note: This MUST be carried out prior to initial powering of the device.
The FDS303 will carry out an automatic Optical Test Calibration at
this point.
Assess requirement for
opening the enclosure, for
maintenance or cleaning,
follow steps 6 to 14.
6
Open the detector enclosure if required, by removing the enclosure cover.
This exposes the enclosure flame path and detector lens.
Avoid damage to the flame
path, faceplate and lens.
7
Clean the enclosure cover and body flame paths with a dry clean cloth to
remove and contamination. If the flame path or threads are badly pitted
the components should be replaced.
8
Check the ‘O’ ring seal on the enclosure cover is not damaged or perished,
replace as required. Note the ingress protection is compromised if the seal
is not correct.
9
Clean the enclosure faceplate (inside) with a mild detergent solution and a
soft cloth until the window is clear of all contamination. Wash the window
thoroughly with clean water and dry with a clean lint free cloth or tissue.
10
Non–setting waterproof grease should be evenly applied to the flame path
on both the enclosure cover and body.
11
Clean the detector lens. This should be done with a soft, dry and clean
cloth.
Avoid touching the optics
or electronics.
12
Clean the detector enclosure faceplate. Use a degreasing agent on the
outside to remove deposits.
13
The enclosure cover must be screwed on to a minimum of 5 full turns or
until fully tight and secured using the locking screw provided.
14
Reinstate the detector back into service.
15
Ensure that inhibits are applied, then, using the flame test torch, function
test the detector. Note the detector LED indicator, within the detector
housing, changes colour to RED. Check the mA output is indicating 18mA.
Check the complete
display system for correct
function and indication.
16
Isolate the power to the detector and ensure a fault is initiated within the
control system. Check the Ma output is indicating 0mA.
