European foreword
This document (EN 54-22:2015/prA1:2017) has been prepared by Technical Committee CEN/TC 72
“Fire detection and fire alarm systems”, the secretariat of which is held by BSI.
This document is currently submitted to the CEN Enquiry.
This document has been prepared under a mandate given to CEN by the European Commission and the
European Free Trade Association, and supports essential requirements of EU Regulation 305/2011.
For relationship with EU Directive, see informative Annex ZA, which is an integral part of
EN 54-22:2015.

1 Modification to 4.6.1 Dry heat (endurance) for sensing element
Replace 4.6.1.2 with:
"4.6.1.2 Dry heat (endurance) for sensor control unit and sensing element
The sensor control unit and the sensing element of the RLTHD shall be capable of withstanding long
term exposure to high temperature as specified in 5.6.1.2."
2 Modification to 5.1.5.3 Multipoint heat detectors
Replace the second paragraph of 5.1.5.3 with:
"When testing the response time of multipoint detectors, one single sensors of the multipoint detector
shall be placed in the centre of the tunnel measuring section (see Annex E). All other sensors shall be
outside the heat tunnel and shall remain at ambient temperature (23 ± 5) °C during the measurement
unless otherwise stated in the individual tests."
3 Modification to 5.1.7 Test schedule
th
In the first column, replace the 11 row, reading "Dry heat (endurance) sending element" with:
"Dry heat (endurance) sensor control unit and sensing element"
4 Modification to 5.5.2.2.3.1 Mounting of the sensing element
Replace the second and third Paragraph (after Note) with:
"When testing the response temperature of multipoint detectors, one single sensor within a 10 m
section of sensing element L shall be placed in the tunnel measuring section as described in Annex E.
test
The position of the part of the sensing element under test (L ) shall be chosen such that it represents
test
the least sensitive response behaviour of the RLTHD. A typical example of a test setup is shown in
Figure E.1."
5 Modification to 5.6.1.2 Dry heat (endurance) sensing element
Replace 5.6.1.2 with:
"5.6.1.2 Dry heat (endurance) for sensor control unit and sensing element
5.6.1.2.1 Object of the test
To demonstrate, if applicable, the ability of the RLTHD sensor control unit and sensing element to
withstand long term ageing effects.
5.6.1.2.2 Principle
The test consists of exposure of the sensor control unit and the sensing element specimens to the high
temperature, for a long period to accelerate ageing effects.
The test shall be conducted consecutively for the sensor control unit and the sensing element. However,
in case the temperature conditioning for the sensor control unit and the sensing element is the same,
testing may be conducted simultaneously.
5.6.1.2.3 Reference
The test apparatus and procedure shall be as described in EN 60068-2-2:2007.
EN 54-22:2015/prA1:2017 (E)
5.6.1.2.4. State of the specimen during conditioning
The sensor control unit and the sensing element specimens shall not be supplied with power during
conditioning and tests for non heat-dissipating specimens shall apply (Test B).
The length of sensing element used in the test shall correspond to the most unfavourable operating
condition of the RLTHD technology under test. The configuration shall be the same as chosen in 5.1.5.
The length of sensing element to be exposed to the heat shall be the 10 m section L which is to be
Test
used for the response test (see 5.1.5.).
The section of the sensing element to be exposed to the dry heat may be disconnected from the
remainder of the sample and its open ends may be sealed in accordance with the manufacturer’s
instructions.
5.6.1.2.5 Conditioning
Conditioning shall be applied to the specimen as indicated in the Table 6 and Table 7.

5.6.1.2.6 Final measurements
After the conditioning and a recovery period of at least 1 h, the functional test as described in 5.1.5 shall
be conducted at a rate of rise of 3 Kmin-1 and the response time recorded.
EN 54-22:2015/prA1:2017 (E)
The greater response time value measured in this test and that measured for the same specimen in the
reproducibility test, shall be designated t(3)max and the lesser shall be designated t(3)min.
5.6.1.2.7 Requirements
No alarm or fault signal shall be given after powering the sensor control unit together with the sensing
element at the end of the conditioning and recovery periods.
The ratio of the response times t(3) : t(3) shall be not greater than 1,3."
