Aspirating Smoke Detection Systems in Saudi Arabia: Design & Selection Guide

Those holes are the sampling points. Their position matters because the system needs to collect air from the spaces included in the protection design. Pipe routes and airflow also affect how the air reaches the detector.

You’ll also see the name VESDA in catalogues. It’s a brand of ASD equipment. When asking for a price or a replacement, use the specific model name so the supplier can check its capabilities and limits.

Access matters in a hospital. A detection plan needs to account for concealed spaces and the work involved in inspecting equipment while the building remains in use.

There’s a useful example at Duna Medical Center in Budapest. Securiton describes aspirating detectors above the lobby’s suspended ceiling and in electrical shafts. ASD was selected for particular spaces within the hospital’s wider fire detection system.

A production building raises different questions. In Securiton’s Tata factory case study, the buildings in Hosur, India, are 12 metres high. For a facility with that kind of height, the proposed sampling arrangement and access for servicing need attention early in the design.

Cold rooms bring temperature into the decision. Securiton reports ASD installations at Magnavale’s UK cold-storage facilities, where storage temperatures reach −20°C. Check the selected equipment’s operating limits and how the design deals with condensation or icing.

EMAN FTC’s smoke and beam detection catalogue can help you identify equipment to discuss with the engineer. Request the exact model’s documentation before accepting it for the project.

Ask for a drawing you can follow. It should identify the protected spaces, sampling locations, pipe routes and detector positions. If part of the building is outside the scope, that should be clear too.

For VESDA installations, Xtralis ASPIRE is one of the manufacturer’s tools for checking the proposed network and producing design reports. The results need to relate to the equipment and layout being supplied.

A pipe route changed to avoid a duct may become longer than the original design. Have the revised layout checked and recorded before installation continues.

Keep the existing fire alarm panel in this discussion. Its make and model help determine which interfaces can be used and how alarm and fault signals will be monitored. Any connection to shutdown or suppression equipment needs to follow the approved cause-and-effect design.

For a Saudi project, ask the consultant which SBC 801 requirements, standard editions and approval documents apply. Settle that during the design review, while changes are still easier to make.

The commissioning report should give you something to refer back to when the system needs attention later.

Useful records include:

• Airflow readings and smoke transport-time results.
• Alarm, fault and interface test results.
• The agreed design documents and as-built drawings.
• Equipment information and maintenance instructions.

Smoke transport time means the time taken for smoke to travel through the pipe network to the detector. Xtralis explains the role of recorded test results in its benchmark testing guidance. Those readings help establish a reference for later checks.

Before accepting the handover, make sure the documents describe what was installed. If the pipework changed on site, the drawings and relevant design checks should reflect the change.

A detection system stays in the building while the building keeps changing. Storage racks move. Rooms are divided. Ventilation is altered.

If that happens in an area protected by ASD, ask for the design to be reviewed. Keep a record of any alterations so the next maintenance visit starts with accurate information.

Routine attention also needs to cover the filters, sampling holes, pipe condition and detector faults. The equipment instructions and site conditions should determine the work and inspection frequency. Dust needs to be considered when agreeing that maintenance scope.

For an existing installation, EMAN FTC’s fire alarm maintenance page outlines related inspection and fault-support services.

Two quotations can both say “ASD system” and cover different amounts of work. One may include network design and commissioning; another may cover equipment supply alone.

Ask each contractor to price the same agreed scope. Find out whether it includes pipework, interfaces, testing and handover documents. Access equipment and work outside normal operating hours can also affect the installation price.

For a replacement, send photographs of the existing equipment labels with the enquiry. Include the detector’s model number and the details of the existing panel so the supplier can check compatibility.

A useful comparison comes from a defined layout and scope. Floor area alone leaves too many details unresolved.

Use EMAN FTC’s aspirating smoke detection equipment catalogue to shortlist detectors and sampling accessories. Ask for the model datasheet and the network-design instructions when you enquire.

If the installation needs connections to an existing panel, review the fire alarm interface equipment as part of the same enquiry. The wider fire alarm product range covers other equipment that may be included in the project.

For support with a project in Riyadh, Dammam, Jubail or Jeddah, EMAN FTC’s fire alarm services page explains its related installation and commissioning work. You can contact the team with your drawings and existing panel details to discuss the requirement.
