An enquiry labelled BLASI ESD, SA or “MRI/CT shielding door” needs an exact product identity and applicable documents before performance or interfaces can be assessed. The official brand information reviewed here does not, by itself, establish either code's specialist capabilities. MRI and CT use different technologies, and a DICOM reference does not replace a door-control interface description. This guide is a document-review method, not a specification for an approved specialist door.
Separate a verified brand entry from an unidentified model
ASSA ABLOY Entrance Systems' official BLASI heritage entry identifies bespoke sliding, revolving, curved and security door systems within its offering. That provides a route for product enquiries, but does not identify the ESD or SA code on a particular proposal or existing entrance.
Do not expand an acronym into a protective function or assume that one code is another with a fire module added. Failure to obtain a matching document in this review is not proof that a historical model never existed, has been discontinued or can be replaced by a different product.
Retain the original wording on equipment, drawings or supply records, including suffixes and revisions. Record the source and completeness of the information. A similar photograph or sales page should not be relabelled as manufacturer evidence.
MRI, CT, DICOM and BLASI answer different questions
| Name in the enquiry | Basic meaning checked for this review | Door-system conclusion that does not follow |
|---|---|---|
| MRI | FDA describes magnetic fields and radiofrequency energy, without ionising radiation | CT protection documents cannot simply be reused, and no particular door is established as suitable |
| CT | FDA describes specialised X-ray equipment for imaging | A room name does not determine door materials, construction or protection values |
| DICOM | Its official overview concerns medical images and related information | The name alone does not establish door wiring, a safety interlock or fault response |
| BLASI | The official heritage entry identifies automatic-door product categories | A brand name does not establish the exact model, protective capability or project service scope |
The imaging information is included only to prevent documents for different subjects being treated as equivalent. It is not examination advice or a protection design. MRI not using ionising radiation does not remove the need to address its magnetic and radiofrequency environment through the appropriate project specialists.
Make the document request identifiable
A useful request states the location, exact wording on the equipment or original order, relevant control-component identification and the question being resolved. Ask the provider to identify the applicable equipment, document edition and limits. Leave unknown details outstanding rather than inventing a suffix to complete a form.
For an existing entrance, safely obtainable external identification, the full operating-unit display and previous service records can help. Information inside covers or near electrical and moving parts should be obtained by appropriately qualified and authorised personnel. An ordinary user should not remove covers or disconnect equipment merely to obtain a photograph.
When documents arrive, retain the title, number, revision, internal application scope, supplying party and receipt date. A webpage title, download name and cover can provide different clues. Read the document's equipment scope rather than relying only on a familiar name.
Keep the operator, assembly, performance and interface evidence distinct
| Subject to establish | Information to request | Boundary to retain |
|---|---|---|
| Operator and control system | Complete identification, control version, fitted components and correct instructions | Movement of the leaf does not establish a specialist room or assembly requirement |
| Door assembly and associated construction | Proposed leaf, frame, glazing, hardware, surroundings and related evidence | A material description alone does not verify the complete construction |
| Performance or test document | Exact subject, method, conditions, result and application scope | Evidence cannot be extended automatically to another size, material or installation |
| Related system interface | Signal source and receiver, intended response, feedback and recovery arrangements | A protocol name or “integration available” is not the interface and verification record |
Put these subjects in one document index without merging them into an undefined “all-function shielding door”. Assign an owner and next action to each missing answer. A product brochure should not become the assumed evidence for every project requirement.
A DICOM statement still leaves door-control questions
Identify the equipment, system layer and function to which the statement refers. The responsible parties need the actual interface and implementation documents, including the signal source, receiving device, permitted response, necessary feedback and handling of missing signals, faults and restoration.
A particular project may have a defined integration arrangement. Review that arrangement on its evidence. A DICOM label alone does not establish exposure-related safety interlocking, direct operator control or a universal wiring method. This guide neither rules out every DICOM-related integration nor provides unverified terminals, converters or connection instructions.
Fire inputs and power loss likewise need separate descriptions of the event, operator, locks, supply and restoration responsibilities. Do not infer automatic opening or automatic return to normal solely from a suffix or brand. See the door-safety and emergency-state guide for a structured record of the questions.
Record what is known and what is still missing
Useful statuses include “obtained and identifiable”, “document available but applicability unresolved”, “awaiting another specialist” and “not obtained”. These are review statuses, not acceptance results. A missing document is not, on its own, evidence that a product is defective.
An answer should identify the next action. If the model is uncertain, name the party obtaining its identification. If project requirements are missing, identify their owner. If existing construction is being changed, retain the change and related document references. Acceptance of a price should not silently turn unresolved matters into confirmed ones.
This guide does not give unverified standard widths, power ratings, shielding values, protective ratings or price ranges. Project performance and evidence require the appropriate parties and the actual proposed equipment. Values from another product should not be renamed to fill a missing table.
Supply, refurbishment and fault reporting need different inputs
A new project needs its location, door reference, exact intended function, existing requirements and proposed scope. Refurbishment also needs original equipment, retained components, associated construction and interfaces. A fault report should preserve existing observations, full messages, circumstances and recent changes.
Do not simulate imaging equipment operation, trigger unfamiliar emergency devices, alter wiring or place a person in the closing path to validate a proposal. Where an abnormality could injure someone, control the hazardous area under the site's arrangements and have the responsible personnel secure it and arrange appropriate checks. A door moving again does not establish a specialist function.

It is not a manufacturer model list, a test report or project approval. The Chinese document guide provides the corresponding Chinese sheet.
Sources, limits and enquiries
Reviewed on 2 November 2026: ASSA ABLOY Entrance Systems' official BLASI heritage entry; FDA's MRI, MRI Benefits and Risks, and Computed Tomography information; and the official DICOM Overview. Only basic information relevant to document identification is used. These sources do not establish approval for a specific entrance or a requirement in another country.
This review did not obtain manufacturer documents sufficient to map ESD and SA to the old page's performance, price and interface assertions. Those assertions are not retained. Any later documents should be checked by subject and scope before a product conclusion is added.

Frequently asked questions
Is BLASI ESD verified here as a shielding door for MRI or CT rooms?
This review did not obtain sufficient exact-model manufacturer evidence for that conclusion. A brand entry, legacy sales text or acronym does not independently establish specialist capability. Identify the equipment, complete configuration and applicable documents first.
Is BLASI SA simply ESD with a fire module added?
Do not infer that relationship from letters or the old page. It was not verified here. Request exact-model and applicability information from the supply or technical-document party before comparing capabilities or prices.
Can MRI and CT door-protection documents be used interchangeably?
Not merely because both are imaging rooms. FDA describes MRI as using magnetic fields and radiofrequency without ionising radiation, while CT uses X-ray equipment. The appropriate specialists must define the actual door and room requirements.
Does a DICOM reference establish a working door safety interlock?
Not on its own. Identify the system, equipment, actual interface documents, response and fault/restoration arrangements, then have the responsible parties review implementation and verification. A standard name is not a wiring instruction.
Does absence from a current search prove a legacy code never existed?
No. It means the matching information was not obtained in that search. Preserve original identification and continue the appropriate enquiry rather than declaring the model nonexistent, discontinued or interchangeable.
Is the completed evidence worksheet specialist-door acceptance?
No. It is a blank tool for organising documents and unresolved questions. Technical verification, performance assessment and project acceptance require the appropriate parties, actual equipment and complete construction under applicable requirements.
Reference information only; the manufacturer's official data takes precedence.
