In this article, we outline how voice alarm system regulations are structured in Spain, who is responsible for ensuring compliance, and the implications for both new construction and retrofitting of existing facilities.
Which standards apply to voice alarm systems?
The principal standard in this area is UNE-EN 54, the Spanish adaptation of the European standard EN 54. This regulation defines the technical requirements that must be met by the components of a voice alarm system, including evacuation loudspeakers, voice alarm control and indicating equipment, and even their power supply units.
When is compliance required?
The Spanish Building Technical Code (CTE), specifically its Basic Document on Fire Safety (DBSI), determines where voice alarm and/or fire detection systems are mandatory, and which regulations apply. At present, public address and voice alarm systems are required in the following cases:
- Hospitals and healthcare buildings: mandatory in all circumstances.
- Public assembly buildings: where the occupancy exceeds 500 people or the surface area is greater than 500 m².
In industrial settings, compliance is defined under the recently updated RSCIEI (Regulation on Fire Safety in Industrial Establishments):
- Industrial facilities: where the surface area is equal to or greater than 10,000 m².
Additionally, the Basic Document on Safety of Use and Accessibility (DBSUA) sets specific accessibility requirements for areas such as adapted toilets and accessible call points.
Complementary Regulations: RIPCI, RSCIEI and ITCs
The RIPCI (Regulation on Fire Protection Installations) governs the design, execution, and maintenance of fire protection systems. The RSCIEI focuses specifically on industrial premises, while the ITCs (Complementary Technical Instructions) define additional requirements depending on the type of building or sector involved.
In practice, these are the regulations that dictate how voice alarm and public address systems should be implemented.
Recent regulatory changes for industrial establishments
Spain’s Council of Ministers has recently approved an amendment to the fire protection regulations, published in the official state gazette (BOE). This update introduces new technical criteria for large-scale industrial environments and reinforces the importance of adhering to strict design and maintenance requirements in factories, power plants, warehouses, and similar facilities. It has direct implications for both ongoing and future projects.
We’re here to support you
At OPTIMUS, we design and supply EN 54-certified public address and voice alarm systems fully compliant with CTE, RIPCI, RSCIEI and the relevant ITCs for each sector. Our solutions also cover areas such as refuge points, accessible toilets, road tunnels, and adapted help points, ensuring full compliance with the latest standards.
To help you better understand the current regulatory framework, we’ve created a downloadable guide which includes the most recent updates concerning industrial premises.
