Fire alarm planning guide –
Focus on EN 54-23

Introduction DIN EN 54-23

Since the introduction of DIN EN 54-23 for optical
signalling devices for fire alarm systems in all
European Union Member States on January
1st 2014 only authorized optical and optical­acoustical signalling devices are permitted. In
Germany this standard is valid since 2017,
based on the revised planning and design
standard, because the EN 54-23 standard is
a product and testing standard and not an
application standard.

The purpose of this brochure is to give a basic
knowledge regarding the planning of signalling
devices, with the example of AVENAR all-in-one

4000.

The standard DIN EN 54-23 assists planners
in planning and designing optical and optical­acoustical signalling devices (the acoustic part
is treated according to DIN EN54-3) in a building.
The standard defines how and in which quantity
signalling devices are needed in a technical
building planning.

The purpose of optical signalling devices is to alert persons in a
building or who are near to a building in case of fire, so that they
can protect themselves or be evacuated in time.

The following table shows the installation categories of
DINEN 54-23 described with letters C (ceiling mounting),
W (wall mounting) and O (open, for individual mounting).
These three categories are explained in the following chapters.
Furthermore, in the table below, you can find the main
requirements for DIN EN 54-23.
