NOTE 1 For the purposes of this clause the term ire suppression system is synonymous with the term ixed firefighting system adopted by CEN)TC 191.
NOTE 2 For the purposes of this clause the term ire detection system is synonymous with the term ire detection and alarm system adopted by CEN!TC 72 and defined in EN 54—1.
The type of fire detection (and alarm) system and firefighting system selected for each space shall take into account the Protection Class of the space and approach to be taken to maintaining the function of the space. For example, maintenance of function may be considered as a time period adequate to implement a disaster recovery programme i.e. by transferring the function of the data centre space to another space within or external to the data centre.
The Protection Classes feature increasing levels of fire detection and reaction. The areas of the data centre requiring the greatest protection against internal fire events will be accommodated in spaces with the highest Protection Class.
This Clause addresses the fire detection and alarm, fixed and portable firefighting systems to be applied to the data centre spaces. It does not intentionally conflict with national or local regulations concerning fire safety. The impact of fire-fighting procedures on the availability of the facilities and infrastructures in the data centre spaces shall be considered, including fire-fighting procedures, which require the disruption of all power supplies (including back-up systems) in non-data centre spaces.
7.1.2 Fire compartments and barriers
7.1.2.1 RequIrements
The data centre spaces shall be considered as a series of fire compartments each with its own objectives for fire detection, alarm and suppression.
All the components comprising, and any pathways that penetrate, the boundary of a fire compartment shall take into account the potential for spread of fire and combustion products (smoke and toxic gases).
The walls and barriers separating the fire compartments shall have a minimum fire rating in accordance with the requirements of the highest Protection Class present at the boundary of the fire compartment. The resistance rating of doors or windows in a wall shall comply with the resistance rating of the walls and barriers. Their ability to resist the impact of firefighting water shall be taken into account.
Advice regarding the scheduling, installation sequence and suitability of particular fire-stopping techniques shall be sought from both the manufacturer and specialist contractors at the earliest possible opportunity.
Fire-stopping techniques applied to pathways that penetrate the boundary of a fire compartment shall be specified in terms of:
a) the fire rating, construction details and orientation of the fire compartment structure;
b) the type, size and material of the fire barrier penetration to be fire-stopped:
c) where there is no housing surrounding the components passing through the fire barrier, the size of the fire barrier penetration and the percentage fill at the penetration:
d) where there Is a housing surrounding the components passing through the fire barrier, the size of the penetration internally and the percentage fill within the housing:
e) a detailed description of the fire-stopping system including any additional supports required for the components passing through the penetration.
The fire-stopping technique applied shall be proven to meet the specification criteria using the test methods given in EN 1366-3, Techniques based upon interacting components shall be regarded as a complete system and should only be used as such.
NOTE Additional information regarding high performance tire-stopping techniques can be sought from the offshore and petrochemical industhes
The system specifier shall:
1) obtain documentary evidence from the manufacturer/supplier which defines the capability of the fire- stopping technique;
2) verify that the proposed specification is covered within the scope of this document;
3) ensure that the fire-stopping technique is fit for purpose.
Fire-stopping techniques shall be installed in accordance with the manufacturers1supplier’s installation instructions. BS/EN 50600-2-5-2016 pdf download.
