Avalanche Beacons operating at 457 kHz - Transmitter-receiver systems - Part 1: Harmonised Standard for access to radio spectrum

The present document specifies technical characteristics and methods of measurements for avalanche beacon
transmitter-receiver systems operating from 456,9 kHz to 457,1 kHz. The frequency range 456,9 kHz to 457,1 kHz is
EU wide harmonised for emergency detections of buried victims and valuable items devices according to Commission
Implementing decision (EU) 2019/1345 [i.9].
An avalanche beacon comprises in one unit at least a transmitter/receiver including antenna and battery.
NOTE: The relationship between the present document and essential requirements of article 3.2 of Directive
2014/53/EU [i.1] is given in annex A.

Foreword

This Harmonised European Standard (EN) has been produced by ETSI Technical Committee Electromagnetic

compatibility and Radio spectrum Matters (ERM).

The present document has been prepared under the Commission's standardisation request C(2015) 5376 final [i.2] to

provide one voluntary means of conforming to the essential requirements of Directive 2014/53/EU on the harmonisation

of the laws of the Member States relating to the making available on the market of radio equipment and repealing

Directive 1999/5/EC [i.1].

Once the present document is cited in the Official Journal of the European Union under that Directive, compliance with

the normative clauses of the present document given in table A.1 confers, within the limits of the scope of the present

document, a presumption of conformity with the corresponding essential requirements of that Directive and associated

EFTA regulations.

The present document is part 1 of a multi-part deliverable covering avalanche beacons operating at 457 kHz transmitter-

receiver systems, as identified below:
Part 1: "Harmonised Standard for access to radio spectrum";
Part 2: "Harmonised Standard for features for emergency services";

Part 3: "Harmonized EN covering essential requirements of article 3.3e of the R&TTE Directive".

NOTE: This part 3 is obsolete and has been replaced with ETSI EN 300 718-2 [2].

Foreword

This Harmonised European Standard (EN) has been produced by ETSI Technical Committee Electromagnetic

compatibility and Radio spectrum Matters (ERM).

The present document has been prepared under the Commission's standardisation request C(2015) 5376 final [i.2] to

provide one voluntary means of conforming to the essential requirements of Directive 2014/53/EU on the harmonisation

of the laws of the Member States relating to the making available on the market of radio equipment and repealing

Directive 1999/5/EC [i.1].

Once the present document is cited in the Official Journal of the European Union under that Directive, compliance with

the normative clauses of the present document given in table A.1 confers, within the limits of the scope of the present

document, a presumption of conformity with the corresponding essential requirements of that Directive and associated

EFTA regulations.

The present document is part 1 of a multi-part deliverable covering avalanche beacons operating at 457 kHz transmitter-

receiver systems, as identified below:
Part 1: "Harmonised Standard for access to radio spectrum";
Part 2: "Harmonised Standard for features for emergency services";

Part 3: "Harmonized EN covering essential requirements of article 3.3e of the R&TTE Directive".

NOTE: This part 3 is obsolete and has been replaced with ETSI EN 300 718-2 [2].

1 Scope

The present document specifies technical characteristics and methods of measurements for avalanche beacon

transmitter-receiver systems operating from 456,9 kHz to 457,1 kHz. The frequency range 456,9 kHz to 457,1 kHz is

EU wide harmonised for emergency detections of buried victims and valuable items devices according to Commission

Implementing decision (EU) 2019/1345 [i.9].

An avalanche beacon comprises in one unit at least a transmitter/receiver including antenna and battery.

NOTE: The relationship between the present document and essential requirements of article 3.2 of Directive

2014/53/EU [i.1] is given in annex A.

Intellectual Property Rights
Essential patents

IPRs essential or potentially essential to normative deliverables may have been declared to ETSI. The information

pertaining to these essential IPRs, if any, is publicly available for ETSI members and non-members, and can be found

in ETSI SR 000 314: "Intellectual Property Rights (IPRs); Essential, or potentially Essential, IPRs notified to ETSI in

respect of ETSI standards", which is available from the ETSI Secretariat. Latest updates are available on the ETSI Web

server (https://ipr.etsi.org/).

Pursuant to the ETSI IPR Policy, no investigation, including IPR searches, has been carried out by ETSI. No guarantee

can be given as to the existence of other IPRs not referenced in ETSI SR 000 314 (or the updates on the ETSI Web

server) which are, or may be, or may become, essential to the present document.
Trademarks

The present document may include trademarks and/or tradenames which are asserted and/or registered by their owners.

ETSI claims no ownership of these except for any which are indicated as being the property of ETSI, and conveys no

right to use or reproduce any trademark and/or tradename. Mention of those trademarks in the present document does

Foreword

This draft Harmonised European Standard (EN) has been produced by ETSI Technical Committee Electromagnetic

compatibility and Radio spectrum Matters (ERM), and is now submitted for the combined Public Enquiry and Vote

phase of the ETSI standards EN Approval Procedure.

The present document has been prepared under the Commission's standardisation request C(2015) 5376 final [i.2] to

provide one voluntary means of conforming to the essential requirements of Directive 2014/53/EU on the harmonisation

of the laws of the Member States relating to the making available on the market of radio equipment and repealing

Directive 1999/5/EC [i.1].

Once the present document is cited in the Official Journal of the European Union under that Directive, compliance with

the normative clauses of the present document given in table A.1 confers, within the limits of the scope of the present

document, a presumption of conformity with the corresponding essential requirements of that Directive and associated

EFTA regulations.

The present document is part 1 of a multi-part deliverable covering avalanche beacons operating at 457 kHz transmitter-

receiver systems, as identified below:
Part 1: "Harmonised Standard for access to radio spectrum";
Part 2: "Harmonised Standard for features for emergency services";

Part 3: "Harmonized EN covering essential requirements of article 3.3e of the R&TTE Directive".

NOTE: This part 3 is obsolete and has been replaced with ETSI EN 300 718-2 [2].
Proposed national transposition dates
Date of latest announcement of this EN (doa): 3 months after ETSI publication
Date of latest publication of new National Standard
or endorsement of this EN (dop/e): 6 months after doa

Date of withdrawal of any conflicting National Standard (dow): 18 months after doa

1 Scope

The present document specifies technical characteristics and methods of measurements for avalanche beacon

transmitter-receiver systems operating from 456,9 kHz to 457,1 kHz. The frequency range 456,9 kHz to 457,1 kHz is

EU wide harmonised for emergency detections of buried victims and valuable items devices according to [i.9].

An avalanche beacon comprises in one unit at least a transmitter/receiver including antenna and battery.

NOTE: The relationship between the present document and essential requirements of article 3.2 of Directive

2014/53/EU [i.1] is given in annex A.
