What does NACE 27.9 cover?

NACE 27.9 (Manufacture of other electrical equipment) classifies manufacturers of a broad range of specialised electrical devices used in the public sector for safety, operations and infrastructure maintenance.

Group 27.9 is broken down into the following classes:

Public contracting authorities relevant for NACE 27.9 are fire brigades and civil protection authorities (siren systems), the Bundeswehr (welding equipment for maintenance), municipal works depots and road maintenance authorities, public transport infrastructure (railway station public address systems) and security authorities (alarm systems).

Public Tenders: Scope of NACE 27.9

Specialised electrical equipment covers a wide range of public needs — from the civil protection siren and railway station public address systems to the workshop welding equipment for municipal works depots.

Typical Contract Types

• Siren systems and warning installations: Digital siren systems for civil and disaster protection; renewal and expansion of municipal warning networks under the Federal Siren Programme
• Public address (PA) systems: Sound systems for railway stations, airports, public buildings and event venues under public ownership
• Fire detection and alarm systems: Electrical fire detection systems, evacuation alarm systems for public buildings (in accordance with DIN 14675)
• Welding equipment for municipal operations: TIG, MIG/MAG and electrode welding equipment for works depots, road maintenance depots and public workshops
• Electrical vehicle equipment: Special electrics for emergency vehicles (fire brigade, THW, police) — warning light systems, special siren and loudspeaker systems
• Power supply units: Industrial power supply units for public infrastructure facilities (tunnels, barriers, point heating)

Thresholds and Procedure Types

Specialised electrical equipment is tendered as supply contracts (EU threshold EUR 221,000). Siren systems and PA systems are often awarded as combined supply and service contracts (including installation, commissioning and maintenance). The Federal Office of Civil Protection and Disaster Assistance (BBK) coordinates the Federal Siren Programme.

Relevant CPV Codes for NACE 27.9

CPV codes (Common Procurement Vocabulary), which must be specified in every notice on TED, bridge the NACE classification and the tender search.

Current tenders can be found on TED (Tenders Electronic Daily) and on national procurement platforms.

Who is NACE 27.9 relevant for in public procurement?

Public Contracting Authorities

The Federal Office of Civil Protection and Disaster Assistance (BBK) coordinates the build-out of a nationwide siren network and funds municipal siren procurement. Municipalities as bodies responsible for disaster protection are in charge of installing and maintaining siren systems. Public transport infrastructure companies (DB, MVG) procure PA systems for railway stations. Municipal works depots and road maintenance authorities procure welding equipment and workshop facilities.

Companies and Bidders

Manufacturers and suppliers of specialised electrical equipment must typically provide the following evidence:

• CE marking: For all electrical operating equipment in accordance with relevant EU directives
• PA standard: Conformity with DIN EN 60849 (Voice alarm systems) for public address systems in safety areas
• Fire detection systems: Specialist contractor qualification under DIN 14675 for fire detection systems
• Welding equipment safety: Conformity with DIN EN 60974 (Arc welding equipment), DGUV regulations
• References: Comparable installations in public buildings or public authorities

Frequently Asked Questions on NACE 27.9 and Public Tenders

What is the Federal Siren Programme, and how are sirens procured?
The Federal Siren Programme (launched in 2021) funds the construction of a comprehensive siren network in Germany. The federal government provides funding; municipalities procure siren heads and control units independently through regular procurement procedures. The BBK issues recommendations for technical standards.

How do I find tenders for PA systems and public address solutions?
On TED via CPV code 32342000 (Loudspeakers) or 35120000 (Surveillance and security systems). Railway station systems for Deutsche Bahn are tendered on DB's procurement platform. Municipal PA systems appear on DTVP and evergabe.de.

What requirements apply to welding equipment in public workshops?
Welding equipment must comply with the German accident prevention regulations of the DGUV (DGUV Regel 100-500) and TRBS 1203. Regular inspections under DGUV Vorschrift 3 (electrical operating equipment) are mandatory. Corresponding test certificates must be specified as suitability requirements in tendering.
