BS EN 54-3:2014 pdf free.Fire detection ana fire alarm systems Part 3: Fire alarm devices – Sounders.
BS EN 54-3 specifies the requirements,test methods and performance criteria for fire alarmsounders,including voice sounders, in a fixed installation intended to signal an audible warning between thefire detection and fire alarm systems and the occupants of a building (see EN 54-1:2011).
This European Standard provides for the assessment and verification of constancy of performance (AVCP) offire alarm sounders to this EN.
This European Standard is not intended to cover:
a) loudspeaker type devices primarily intended for emitting emergency voice messages that are generated
from an external audio source;
b) supervisory sounders, for example, within the control and indicating equipment.2Normative references

4 Requirements4.1Compliance
In order to comply with this standard, sounders shall meet the requirements of this clause,which shall beverified by visual inspection or engineering assessment and shall be tested as described in Clause 5 and shallmeet the requirements of the tests.
4.2Operational reliability
4.2.1 Duration of operation
The sounder shall be rated for at least 100 h operation. No limitation by the manufacturer on duty factor ormaximum on-time shall prevent the device from operating the 1 h ‘on 1 h ‘off cycle required by the testprocedure described in 5.2.1.
This requirement does not apply to the capacity of batteries which may be used within sounders as a meansof local storage of operating power. The capacity and charging requirements of such batteries need to meetthe requirement of the system.
4.2.2Provision for external conductors
The sounder,unless it is a radio-linked component not using wires, shall provide space within its enclosure forexternal conductors to be brought in and terminated.Entry holes for conductors or cables shall be provided orthe location where such holes are to be made shall be indicated, by providing a template or some othersuitable means.
Terminals for connecting external conductors to the sounder shall be designed so that the conductors areclamped between metal surfaces without being damaged.
This requirement shall be assessed as specified in 5.2.2.
4.2.3 Flammability of materials
Plastic materials used in the construction of sounders shall comply with the following flammabilityrequirements:
a)EN 60695-11-10:2013 Class v-2 or HB75 for devices consuming less than or equal to 15 W of power;b) EN 60695-11-20:1999 and EN 60695-11-20:1999/A1:2003 Class 5VB for devices consuming more than 15 W of power.BS EN 54-3 pdf free download.
