General Inspection and maintenance of the detector and faceplate.
6 - 14
Specific inspection and maintenance of the detector enclosure.
16
Detector function testing.
1 – 5
Commissioning Procedure.
15 - 17
Step
Activity
Detectors that require maintenance / commissioning should be taken offline
1
and inhibited. Detectors which require to be opened will need to be isolated
electrically.
Ensure that the detector mounting arrangements are secure and
2
undamaged.
3
Ensure that the detector enclosure is intact and undamaged.
Ensure that all associated cables and glands are correctly made up, secure
4
and undamaged.
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.
5
Note: This MUST be carried out prior to initial powering of the device.
The VSF303 will carry out an automatic Optical Test Calibration at this
point.
Open the detector enclosure if required, by removing the enclosure cover.
6
This exposes the enclosure flame path and detector lens.
Clean the enclosure cover and body flame paths with a dry clean cloth to
7
remove and contamination. If the flame path or threads are badly pitted the
components should be replaced.
Check the 'O' ring seal on the enclosure cover is not damaged or perished,
8
replace as required. Note the ingress protection is compromised if the seal
is not correct.
Clean the enclosure faceplate (inside) with a mild detergent solution and a
9
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.
Non–setting waterproof grease should be evenly applied to the flame path
10
on both the enclosure cover and body.
Clean the detector lens. This should be done with a soft, dry, and clean
11
cloth.
Clean the detector enclosure faceplate. Use a degreasing agent on the
12
outside to remove deposits.
The enclosure cover must be screwed on to a minimum of 5 full turns or
13
until fully tight and secured using the locking screw provided.
Reinstate the detector back into service.
14
Ensure that inhibits are applied, then, using the flame test torch, function
15
test the detector. Note the detector LED indicator, within the detector
housing, changes color to RED. Check the mA output is indicating 18mA.
Isolate the power to the detector and ensure a fault is initiated within the
16
control system. Check the Ma output is indicating 0mA.
De-isolate the detector and ensure the status LED indicates green.
17
Reinstate the detector back into service. Check the mA output is indicating
4mA.

Key Points
Ensure that panel wiring,
and terminations
associated with all units
under test are in good
order.
Assess requirement for
opening the enclosure, for
maintenance or cleaning,
follow steps 6 to 14.
Avoid damage to the flame
path, faceplate, and lens.
Avoid touching the optics
