Installation - Pipe work Rules
Apply glue on the outside of the pipe before joining
If using cable ties on cat-wire then tie every 300mm (1 ft)
Ensure appropriate fixings are used
Minimize bends where possible
Follow the rules in Pipe network Design guidep g g
Never glue pipes into the detector manifold
Keep the pipe work neat and tidy
Buy a separate set of drill bits only for VESDA sample holes
– They will remain sharp
– Sizes from 2mm to 8mm should be included
– In 0.5mm steps

Troubleshooting & Maintenance
Filter changed / Pipes cleaned without re- normalizing airflow Check external influences on Pipe work i.e. A/C units , wind in open areas.
Flow Sensor Fail : Codes F19 - F22 If all F19 - F22 codes appear at the same time the sensor cable from Chassis to flow board is most likely to be unplugged. Otherwise these fault codes mean the flow sensor board is faulty.
(Chassis Change Required)

• Always ensure exhaust bung has been removed before normalization.
• Also ensure pipe runs have been calculated using ASPIRE2 and return a minimum of 15ltrs/min per pipe.
• VLF-250 requires an airflow between 12L/min to 24L/min/.• VLF-500 requires an airflow between 12L/min to 52L/min/.

Airflow - Raw Airflow Data
Raw Airflow Data is just that Data. It does not have a volumetric unit of any kind.
It is recommended to record the Raw Air flow at Installation. It should then be checked every 6 months
Troubleshooting & Maintenance
should then be checked every 6 months.
A decrease in Raw Airflow will be indicative of sampling holes becoming progressively blocked.
Raw Airflow will show this, whereas the Percentage Airflow may not if the flow has recently been normalized.

Temporarily remove detector from VESDAnet (insert jumper) and check internal loop is ok. This can be done by checking 2 green LED’s on top of the Head Processor Card.
If internal loop has fault (only 1 LED on) remove Display /Programmer to confirm which node has Comms fault.

Isolating Systems
Isolation of risk zones should only be carried out with thefull knowledge and approval of the appropriatesupervising authority.
Troubleshooting & Maintenance
Always follow site specific isolation requirements as necessary
Isolate FIP first and then detector.

1. Without disturbing the pipe network inspect each pipe run to its full length for any obvious breaks
2. Examine all pipe joints to ensure these are firmly secured
3 Ensure end caps are set firmly in place
Troubleshooting & Maintenance Pipe Network Inspection
3. Ensure end caps are set firmly in place
4. If capillary sampling is used, ensure that the capillaries have not become loose
5. Conduct a simple smoke test. If the system fails to respond it may be necessary to clean the pipes
51
1. Remove capillary tubes from the main sampling pipe.2. Ensure that all the pipes are disconnected from the detector pipe inlet
manifold. 3. Ensure that no foreign materials are able to enter the detector manifold.
Troubleshooting & Maintenance Pipe work Back Flushing
4. Insert a length of flexible tubing into the sampling pipe sealing any gaps between the sampling pipe and the flexible tubing with electrical tape.
5. Connect the relevant flexible tube to a compressed air source (approx. 400 KPAs) and flush pipes for at least 2 minutes.
6. Visually check to see that the sampling points are not blocked.7. Reassemble the sampling point and connect it to the capillary tube.8. Normalize the detector and conduct a smoke test to check for broken
pipes or joints.

A pipe integrity test should be conducted every twelve months. A smoke test is necessary to prove the integrity of the pipe network and to
th t t ti
Troubleshooting & Maintenance Pipe work Testing Methods
measure the transport time.
When testing pipe integrity it is important to perform a smoke test.This can be in the form of :
Can smoke (not in Cold rooms) Mozzie coilIncense Stick
This should be performed in accordance with the applicable maintenance standards. The transport time compared with the original ASPIRE2 calculations.
53
There are two types of tests1. Commissioning test – Aspire 2 Transport time verification2. Performance based test – See below
Materials used to generate smoke in a smoke test should be of a type most likely
Troubleshooting & Maintenance Smoke Testing
to be encountered in a real life situation.
Hot Wire Test - Overheating the outer PVC sheath to a 1meter length of 0.79mm2 cable in a controlled manner.
Alternatively a variable hot plate capable of 200 0C may be used. Other tests as described in EN-54.20 or other standards
