New requirements for fire detection and alarm network systems IP 12 13

BRE (Building Research Establishment) is an independent, research-based consultancy, testing and training organisation, operating in the built environment and associated industries.

New requirements for fire detection and alarm network systems (IP 12/13) was written by Eman Mattie-Suleiman and published by BRE on 30 September 2013.

A fire detection and alarm systems (FDAS) typically consists of a processer unit, which receives signals from detection and activation functions such as smoke and heat detectors and activation of manual call points. After analysis of the incoming signals, the status of the system is indicated via the user interface and the appropriate outputs are initiated such as the activation of sounders/beacons, signals to the alarm receiving centre, or signals to activate protection devices such as extinguishing systems.

The development of FDAS components has been driven by new technology, the growth in microprocessor power at low prices, new legislative requirements and user specifications. Different types of FDAS are now available on the market and the selection of the appropriate system will depend on a number of factors including:

• Building size.
• Complexity of the action(s) to be taken due to a fire event within a building.
• Reliability.
• Cost of the system and its installation.

This 12 page BRE information paper enables the specifiers and designers of fire detection and alarm systems to choose the most appropriate hard-wired network systems whilst maintaining compliance with the Construction Products Regulation (CPR) and BS 5839-1 (Fire detection and fire alarm systems for buildings. Code of practice for design, installation, commissioning and maintenance of systems in non-domestic premises). It also highlights the requirements for network systems which have been developed and incorporated within a Loss Prevention Standards (LPS) standard.

• Background-Introduction of network systems.
• Reasons for networking fire detection and alarm systems.
• Current requirements for fire detection network systems.
• New fire detection and alarm system network requirements.
