ISO 7240-14:2013

Overview

ISO 7240-14:2013 is the ISO standard for fire detection and alarm systems (FDAS) covering the design, installation, commissioning and service of fire detection and fire alarm systems in and around buildings. Its primary aim is early detection and timely notification to protect life by specifying requirements for automatic detection, manual alarm initiation, and audible/visual warnings. The standard also addresses interfaces to ancillary technical services (for example fixed extinguishing systems) and to audible warning systems in accordance with ISO 7240‑19. Protection of property is explicitly outside its scope, though the guidance may be used as recommendations for property protection.

Key topics and technical requirements

ISO 7240‑14 organizes practical requirements for life‑safety FDAS and includes, among others:

• System design and responsibilities - roles and qualifications for designers, installers and maintainers; required documentation and design deliverables.
• Equipment and materials - quality, environmental requirements and compatibility of components.
• Detection design - zoning, detector selection, detector sensitivity and response characteristics, detector location and spacing.
• Manual call points and alarm devices - requirements for manual alarm initiation and audible/visual warning devices.
• Control and indicating equipment - performance, interfaces, power supply and backup supply considerations.
• Commissioning and testing - prescribed commissioning procedures, documentation and certification of correct operation.
• Service and maintenance - service plans, routine tests, records, and qualifications for service personnel.
• Integration and ancillary services - signal outputs to sound systems (ISO 7240‑19), fire suppression systems, smoke/heat control, remote monitoring and delay management.
• Abnormal situations and alterations - guidance for handling faults, system changes and upgrades.

(Annex A provides informative material such as power source calculations.)

Practical applications and users

ISO 7240‑14 is intended for professionals responsible for life‑safety fire alarm systems, including:

• Fire safety designers and consultants
• System integrators and installers
• Commissioning engineers and test teams
• Facilities and building managers responsible for operation and maintenance
• Service providers and maintenance contractors
• Authorities Having Jurisdiction (AHJs) and certification bodies

Use cases include designing new FDAS for commercial, institutional or public buildings; commissioning and certifying installations; and establishing ongoing inspection, testing and maintenance regimes.

Related standards

ISO 7240 is a multipart suite. Relevant related parts include: ISO 7240‑1 (general), ISO 7240‑2 (control and indicating equipment), ISO 7240‑19 (sound systems for emergency purposes), and parts covering detectors, manual call points and other components. Referencing related ISO 7240 parts ensures compatibility across system components and functions.
