Introduction
The purpose of a visual fire alarm device (VAD) is to warn person(s) within, or in the vicinity of, a building of
the occurrence of a fire emergency in order to enable such person(s) to take appropriate measures.
This European Standard allows manufacturers to specify VADs in terms of the range at which the required
illumination is met. Three categories of device are defined, one for ceiling mounted devices, one for wall
mounted devices and an open category. The maximum range of the VAD is tested by measuring the light
output in a hemisphere surrounding it to determine its light distribution. As the light output of some VADs can
change over time due, for example, to the effect of self-heating, a test has been introduced to check that the
variation of light output over time is within an acceptable limit.
This European Standard gives common requirements for the construction and robustness of VADs as well as
for their performance under climatic, mechanical and electrical interference conditions which are likely to occur
in the service environment. VADs are classified in one of two application environment types, i.e. Type A and
Type B. More severe climatic conditions are applied to devices that are primarily intended for outdoor
applications (Type B) than those primarily intended for indoor applications (Type A).
1 Scope
This European Standard specifies the requirements, test methods and performance criteria for visual alarm
devices in a fixed installation intended to signal a visual warning of a fire between the fire detection and fire
alarm system and the occupants of a building (see item C of Figure 1 of EN 54-1:1996). It is intended to cover
only those devices which derive their operating power by means of a physical electrical connection to an
external source such as a fire alarm system.
This European Standard specifies the evaluation of conformity and the marking of the visual alarm devices.
This European Standard applies to visual alarm devices that rely on software for their operation and to those
that do not.
This European Standard applies only to pulsing or flashing visual alarm devices, for example xenon beacons
or rotating beacons. Devices giving continuous light output are excluded from this European Standard.
This European Standard is not intended to cover visual indicators, for example those on detectors or on the
control and indicating equipment.

4.3.1.1 VADs shall meet the requirement for coverage volume of at least one of the following three
categories:
a) 'C', ceiling mounted devices;
b) 'W', wall mounted devices;
c) 'O', open class devices.
4.3.1.2 Category C devices shall be further specified as C-x-y (see 4.3.6.2, d), 1)), where:
 x is either 3, 6 or 9, representing the maximum height, in metres (m), at which the device may be
mounted; and
 y is the diameter, in metres (m), of the coverage cylindrical volume when the device is mounted at the
ceiling height.
EXAMPLE C-3-12 corresponds to a ceiling mounted device giving a coverage cylindrical volume of 12 m diameter at
3 m height.
4.3.1.3 Category W devices shall be further specified as W-x-y (see 4.3.6.2, d), 2)), where:
 x is the maximum height of the devices on the wall, in metres (m), with a minimum value of 2,4 m; and
 y is the width of a square room, in metres (m), covered by the device.
EXAMPLE W-2,4-6 corresponds to a wall mounted device giving a coverage cuboid volume of 2,4 m × 6 m × 6 m
when mounted at a height of 2,4 m.
4.3.1.4 For category O devices the coverage volume in which the required illumination is achieved shall
be specified (see 4.3.6.2, d), 3)).
4.3.2 Variation of light output
When tested in accordance with 5.3.2, the variation in effective luminous intensity of the VAD, over 30 min,
shall be less than 25 %.
4.3.3 Minimum and maximum effective luminous intensity
When tested in accordance with 5.3.3, the VAD shall produce an effective luminous intensity of at least 1 cd
for 70 % of all measurement points and shall not exceed 500 cd for any measurement points.
4.3.4 Light colour
The VAD shall emit a white or red flashing light.
4.3.5 Light temporal pattern and frequency of flashing
The flash rate of the VAD shall be between 0,5 Hz and 2 Hz measured at 10 % of the peak values of
consecutive leading edges of the first pulse of each flash (P ).
10L
NOTE The light temporal pattern and frequency of flashing may vary in different countries. Reference needs to be
made to local regulations.
The maximum on time, measured between the 10 % of peak value of the leading edge (P ) and the 10 %
10L
value of the trailing edge (P ) of the last pulse of the flash shall not exceed 0,2 s.
10T
If the light emitted consists of groups of several pulses and the time between the P of one pulse and the
10T
P of the next pulse is less than 0,04 s then the pulses shall be considered as a single event. Any set of
10L
multiple pulses shall not exceed 0,2 s between the P for of the first peak to the P of the last peak.
10L 10T
A set of pulses where the minimum value does not drop below 10 % of the peak value is considered as a
single pulse and shall not exceed 0,2 s between P and P .
10L 10T
