For the purposes of this standard, the following terms and definitions and those given in EN 54-1:1996 apply:
3.1
typical application temperature
temperature that an installed detector can be expected to experience for long periods of time in the absence
of a fire condition
NOTE This temperature is deemed to be 29 °C below the minimum static response temperature, according to the class
marked on the detector, as specified in Table 1.
3.2
maximum application temperature
maximum temperature that an installed detector can be expected to experience, even for short periods of
time, in the absence of a fire condition

marked on the detector, as specified in Table 1.
3.3
static response temperature
temperature at which the detector would produce an alarm signal if subjected to a vanishingly small rate of
rise of temperature.
-1
NOTE Rates of rise of temperature of approximately 0,2 K min are normally found to be suitable for measuring this,
however lower rates can be required in some instances (see 5.3).
prEN 54-5:2011 (E)
4 Requirements
4.1 General
4.1.1 Compliance
In order to comply with this standard the detector shall meet the requirements clause 4,, which shall be
verified by visual inspection or engineering assessment, shall be tested as described in clause 5. , and shall
meet the requirements of the tests.
4.1.2 Classification
Detectors shall conform to one or more of the following classes: A1, A2, B, C, D, E, F or G according to the
requirements of the tests specified in clause 5 (see Table 1).
Table 1 — Detector classification temperatures
Detector Typical Maximum Minimum Static Maximum Static

detector, by adding the suffix S or R to the above classes . Detectors, which are marked with the letter S or R
as a suffix to the class marking, shall be tested in accordance with the applicable test, specified in
clause 5.3.7, and shall meet the requirements of that test, in addition to the tests of clause 5.

1)
Detectors, with a suffix S to their class, do not respond below the minimum static response temperature, applicable to
their classification (see Table 1), even at high rates of rise of air temperature. Detectors with a suffix R to their class,
incorporate a rate-of-rise characteristic, which meets the response time requirements (see Table 4) for high rates of rise of
air temperature even when starting at air temperatures substantially below the typical application temperature.
prEN 54-5:2011 (E)
4.2 Operational reliability
4.2.1 Position of heat sensitive elements
Each detector shall be constructed such that at least part of its heat sensitive element(s), except elements
with auxiliary functions (e.g. characteristic correctors), shall be ≥ 15 mm from the mounting surface of the
detector. To confirm this, the detector shall be tested in accordance with clause 5.2.1.
4.2.2 Individual alarm indication
Class A1, A2, B, C or D detectors shall be provided with an integral red visual indicator, by which the
individual detector, which released an alarm, can be identified, until the alarm condition is reset. Where other
conditions of the detector can be visually indicated, they shall be clearly distinguishable from the alarm
indication, except when the detector is switched into a service mode. For detachable detectors the indicator
may be integral with the base or the detector head. The visual indicator shall be visible from a distance of 6 m
directly below the detector, in an ambient light intensity up to 500 lux.
Class E, F or G detectors shall be provided with either an integral red indicator, or with another means for
locally indicating the alarm status of the detector. To confirm this, the detector shall be assessed in
accordance with clause 5.2.2.
NOTE The alarm condition is reset manually at the control and indicating equipment (See EN 54-2).
4.2.3 Connection of ancillary devices
Where 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. To confirm
this, the detector shall be assessed in accordance with clause 5.2.3.

indicating equipment) to detect the removal of the head from the base, in order to give a fault signal. To
confirm this, the detector shall be assessed in accordance with clause 5.2.4.
4.2.5 Manufacturer's adjustments
It shall not be possible to change the manufacturer's settings except by special means (e.g. a special code or
tool, or by breaking or removing a seal). To confirm this, the detector shall be assessed in accordance with
clause 5.2.5.
4.2.6 On-site adjustment of response behaviour
If there is provision for on-site adjustment of the response behaviour of the detector then:
a) for each setting, at which the manufacturer claims compliance with this standard, he shall declare a
corresponding class, and for each such setting the detector shall comply with the requirements of this
standard for the corresponding class, 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 the standard.
To confirm this, the detector shall be assessed in accordance with clause 5.2.6.
NOTE These adjustments may be carried out at the detector or at the control and indicating equipment.
prEN 54-5:2011 (E)
4.2.7 Marking
Each detector shall be clearly marked with the following information:
a) the number of this standard and its date(i.e. EN 54-5:2009);
b) the class(es) of the detector (e.g. A1, A1R, A1S, A2, B etc.). If the detector has provision for on-site
adjustment of the class (see 4.2.6), then the marking of the class may be replaced by the symbol P;
c) the name or trademark of the manufacturer or supplier;
d) the model designation (type or number);
e) the wiring terminal designations;
f) some mark(s) or code(s) (e.g. serial number or batch code), by which the manufacturer can identify, at
least, the date or batch and place of manufacture, and the version number(s) of any software, contained
within the detector.
For detachable detectors, the detector head shall be marked with a), b), c), d) and f), and the base shall be
marked with, at least d) (i.e. its own model designation) and e).
Where any marking on the device uses symbols or abbreviations not in common use then these shall be
explained in the data supplied with the device.
The marking shall be visible during installation of the detector and shall be accessible during maintenance.
The markings shall not be placed on screws or other easily removable parts.
To confirm this, the detector shall be assessed in accordance with clause 5.2.7.
4.2.8 Data
Detectors shall either be supplied with sufficient technical, installation and maintenance data to enable their
2)
correct installation and operation or, if all of these data are not supplied with each detector, reference to the
appropriate data sheet(s) shall be given on, or with each detector.
For detectors with provision for on-site adjustment of their class, these data shall identify the applicable
classes and shall describe the method of programming (e.g. by selecting a switch position on the detector or a
setting from a menu in the control and indicating equipment).
To confirm this, the detector shall be assessed in accordance with clause 5.2.8.
NOTE Additional information may be required by organizations certifying that detectors conform to the requirements
of this standard.
