Prefabricated fire protection rooms and documentation: When a preassembled pump-set or a prefabricated room is supplied, the information provided on the declaration is essential for proper and complete certification.
Below is a clear answer, including a list of the documents required to properly certify a prefabricated fire protection system with a load-bearing metal structure manufactured in a workshop.

Declaration under Ministerial Decree 37/2008: When It Is Required
If a pre-assembled pump-set or a prefabricated unit is supplied, is there a specific requirement: must the manufacturer issue a declaration of proper installation in accordance with Ministerial Decree 37/2008?
The answer is yes: it is specified that the manufacturer of the unit must issue the declaration in accordance with Ministerial Decree 37/2008.
Why must the manufacturer issue the declaration?
The key point is that not only is the Pumpset (unit) supplied, but also additional parts that are part of the system.
In particular, in addition to the Pumpset, the manufacturer also supplies and installs the following parts:
- hydraulic
- electric
Precisely because these parts are designated as “part of the system,” the declaration required by Ministerial Decree 37/2008 is the responsibility of the manufacturer that supplies and installs them.
Prefabricated Fire Protection Rooms: Required Documents
To properly certify a prefabricated fire protection system (with a load-bearing metal structure manufactured in a workshop), a list of documents considered essential is provided.
The practical purpose of this list is to avoid gaps in documentation: in presence of prefabricated fire-resistant rooms, the documentation covers not only the pump-set itself, but also the room and its related components.
In the following sections, you will find the documents, presented and organized in a more readable format.
EC Declaration of Conformity for the unit and the room (Directive 2006/42/EC)
The EC Declaration of Conformity is required for:
- to the pressurization unit
- and at the bar
This declaration is indicated as having been drafted in accordance with Annex II A of Directive 2006/42/EC. In practice, within the system documentation, this element formally covers the compliance and classification of the group and the facility.
Structural Report on the Building (UNI EN 1090) and Relationship to the Site
A structural report in accordance with UNI EN 1090 is also required for the premises.
Certain organizational and content-related aspects are specified:
- The report is prepared by a licensed professional;
- It comes with an earthquake-resistance report;
- The report must be related to the installation site.
In addition, an operational prerequisite is specified: in order to prepare this report, it is essential to provide the design engineer with the geological report for the installation site. This step clarifies that this is not a “generic” document, but one specific to the installation context.
CERT-REI and manufacturer’s declaration: R60 fire resistance
The list also includes the local CERT-REI and DICH PROD.
It is stated that the document was prepared by a licensed professional and that it must certify the fire resistance of the load-bearing structure, designated as R60.
This section completes the documentation for the prefabricated building, supplementing the “structural” section with specifications regarding the fire resistance of the load-bearing structure.
DM 37/08 Declaration for the electrical and plumbing systems of the premises
In addition to the declaration regarding the proper installation and the supply/installation of system components, a specific document is explicitly required: the declaration in accordance with Ministerial Decree 37/08 regarding the electrical and plumbing systems of the premises.
This point is consistent with the initial rationale: the prefabricated structure is not limited to the unit itself, but also includes the electrical and plumbing systems associated with it.
Simplified configuration: pressurization unit only (without prefabricated enclosure)
There is one important practical exception: if there is only a pressurization unit (without a prefabricated room), then the documentation requirements are reduced.
Specifically, it is noted that the documents are reduced to:
- the first item on the list
- and the last item on the list
This distinction is useful for avoiding irrelevant documentation requests when the prefabricated building is missing and only the unit is being processed.
Conclusion
In summary: For prefabricated fire suppression rooms, the declaration required under Ministerial Decree 37/2008 is the responsibility of the pump-set manufacturer, because the manufacturer also supplies and installs the hydraulic and electrical components of the system. This is accompanied by a set of essential documents required to properly certify both the unit and the room.
