Overview

EN 54-4:1997 is a CEN European standard that specifies the requirements, test methods and performance criteria for power supply equipment used in fire detection and fire alarm systems installed in buildings. Published as part of the EN 54 series (fire detection and fire alarm systems), this part focuses on the component that supplies electrical energy to detection, control and alarm devices. The standard applies to conventional power supply equipment intended for building-installed fire alarm systems; special-purpose or bespoke power supplies may need additional testing beyond EN 54-4.

Key Topics

EN 54-4 addresses the technical and procedural aspects necessary to ensure reliable power for fire alarm systems. Key topics typically covered include:

• Design and performance requirements for mains-connected power supplies and associated secondary power (batteries or other energy storage).
• Test methods and performance criteria to verify behaviour under normal operation, mains failure and fault conditions.
• Battery and charging system requirements, including monitoring, automatic switching to standby power and recharge performance.
• Fault detection and signalling, such as indicators or outputs for mains failure, battery low, charger fault and general malfunction.
• Endurance and reliability criteria, ensuring continued operation for the required period under stated conditions.
• Environmental and mechanical considerations (e.g., temperature, humidity, vibration) to confirm continued performance in building installations.
• Documentation, marking and installation guidance to support correct use, maintenance and compliance verification.

(EN 54-4 defines the framework; exact numerical performance parameters and test sequences are contained in the full published text.)

Applications

EN 54-4 is used to ensure that power supply equipment for fire detection and alarm systems is reliable, tested and suitable for building safety applications. Typical users and stakeholders include:

• Manufacturers of fire alarm power supplies and battery systems who need to design and certify products.
• System designers and integrators specifying compliant power solutions for commercial, residential and public buildings.
• Installers and maintenance contractors verifying correct installation, replacement and periodic testing.
• Certification bodies and testing laboratories performing type tests and conformity assessments.
• Building owners, facilities managers and safety officers seeking assurance that fire alarm power sources meet established European requirements.

Related Standards

• EN 54‑1 (system components and general requirements) - EN 54-4 references component L as the power supply element.
• Other parts of the EN 54 series that describe detectors, control panels and interfaces.

Keywords: EN 54-4, fire detection, fire alarm systems, power supply equipment, CEN standard, battery backup, power supply requirements, fire alarm power.
