NOTE The term "optical" is used to describe that part of the electromagnetic spectrum produced by the transmitter to which the
receiver is responsive; this is not restricted to visible wavelengths.

3 Terms and definitions
For the purposes of this European Standard the terms and definitions given in EN 54-1:1996 and the following
apply.
3.1
line smoke detector using an optical beam
detector consisting at least of a transmitter and a receiver and which may include reflector(s) for the detection of
smoke by the attenuation and/or changes in attenuation of an optical beam
3.2
transmitter
component from which the optical beam emanates
3.3
receiver
component which receives the optical beam
3.4
optical path length
total distance traversed by the optical beam between the transmitter and the receiver
3.5
opposed component
component [transmitter and receiver or transmitter-receiver and reflector(s)] of the beam detector whose position
determines the optical path
3.6
separation
physical distance between the opposed components [transmitter and receiver or transmitter-receiver and
reflector(s)]
3.7
attenuation
value "C", expressed in dB, of the reduction in intensity of the optical beam at the receiver, defined by the following
equation:
C = 10 log (I /I)
10 0
where
I is the received intensity without reduction in intensity;
0
I is the received intensity after reduction in intensity.
3.8
response threshold value
value of attenuation at the moment an alarm signal is generated by a specimen, when tested in accordance with
5.1.5
3.9
sensitivity adjustment
any adjustment during or after commissioning which leads to a change in the response to fire

4 Requirements
4.1 Compliance
In order to comply with this standard the detector shall meet the requirements of this clause, which shall be verified
by visual inspection or engineering assessment, shall be tested in accordance with clause 5 and shall meet the
requirements of the tests.
4.2 Individual alarm indication
Each detector shall be provided with an integral red visible indicator, by means of which each individual detector
which releases an alarm can be identified, until the alarm condition is reset.
4.3 Connection of ancillary devices
If the detector provides for connections to ancillary devices (e.g. remote indicators, control relays), open or short-
circuit failures of these connections shall not prevent the correct operation of the detector.
4.4 Manufacturer’s adjustments
It shall not be possible to change the manufacturer's settings except by special means (e.g. the use of a special
code or tool, or by breaking or removing a seal).
4.5 On-site adjustment of response threshold value
If there is provision for on-site adjustment of the response threshold value of the detector then:
a) For each setting, at which the manufacturer claims compliance with this standard, the detector shall comply
with the requirements of this standard, and access to the adjustment means shall only be possible by the use
of a code or special tool or by removing the detector from its base or mounting;
b) any setting(s), at which the manufacturer does not claim compliance with this standard, shall only be
accessible by the use of a code or special tool, and it shall be clearly marked on the detector or in the
associated data, that if these setting(s) are used, the detector does not comply with this standard.
NOTE These adjustments may be carried out at the detector or at the control and indicating equipment, for example.
4.6 Protection against ingress of foreign bodies
The detector shall be designed so that a sphere of diameter (1,3 ± 0,05) mm cannot pass into any enclosure
containing active opto-electronic components, when the detector is in operat
