all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is

– 12 – 62642-4 © IEC:2010
5.1.2 Acoustic
A warning device shall produce a varying sound output, which is distinctive and likely to
attract attention, with a mean acoustic output of no less than that defined in Table 3 at 1 m
from the mounting surface of the warning device throughout the manufacturers specified
operating voltage range. Peak acoustic output levels, taken at 30° intervals in the horizontal
plane, shall not be below the minimum individual level defined in Table 3 at 1 m from the
mounting surface. The mean acoustic output shall be calculated by the arithmetic sum of
these values divided by the number of measurements. For surface mounted devices (e.g. wall
mounted devices) this is required at angles between 15° and 165° to the surface, and for pole
mounted devices, it is for the full 360°.

NOTE 1 It is considered restrictive to define exact waveforms of acceptable alarm tones, therefore the
only tests that can be applied are on the acoustic output level and that the tone is varying.
NOTE 2 Voice alarms are deemed to meet the requirements of a varying sound output.
NOTE 3 A warning device may also provide audible alert indications providing such indications are
easily distinguishable from an alarm.
NOTE 4 The acoustic output (sound level and/or frequency) of a warning device may be subject to
variation depending on local or national requirements.

5.1.3 Timing
A trigger command exceeding 400 ms shall be processed by the warning device.
A warning device shall commence its audible alarm within 1 s of receiving a valid trigger
command to do so. It shall cease its audible alarm within 1 s of receiving a valid cancellation
of the trigger command.
The warning device shall sound between these signals.
The maximum time for which an audible warning device shall sound continuously is 15 min.
NOTE 1 Where applicable this requirement may be achieved by the CIE.
NOTE 2 The duration of the operational period of a warning device may be subject to variation depending on local
or national requirements
A tamper signal or message shall be generated within 1 s of a tamper condition occurring.
There shall be a response to loss of remote power source or loss of trigger command
interconnection integrity according to Tables 1 and 2, within 10 s of the fault occurring.
A response to local test fail according to Tables 1 and 2 shall occur within 10 s of detection of
the fault.

5.2.2 Detection
The tamper detection requirements for warning devices relative to the security grade are
given in Table 6.
Opening the warning device enclosure by normal means shall generate a tamper signal or
message. The enclosure shall not permit the introduction of a tool of dimension as specified in
Table 5 and type as specified in IEC 60529, to defeat the tamper detection.
Attempts to remove the warning device from its mounting surface for a distance defined in
Table 7 in a perpendicular direction shall generate a tamper signal or message according to
Table 6.
It shall not be possible to defeat the removal from mounting detection by sliding a
25 mm × 1 mm × 300 mm blade, or by use of pliers (of thickness 5 mm and reach 150 mm),
between the mounting surface and the warning device.
The warning device shall include means to detect penetration of the enclosure, which could
cause mis-operation of the warning device, as specified in Table 6, when a hole of 4 mm is
made in the enclosure.

NOTE 1 A type W warning device could, for example, have a dry cell as its only means of power. This storage
device has no means of recharge, and will need replacing before it is completely exhausted.
NOTE 2 A type X warning device could, for example, be remotely powered from the I&HAS and with a dry cell as
its storage device. This storage device has no means of recharge, and will need replacing before it is completely
exhausted.
NOTE 3 A type Y warning device could, for example, recharge its storage device by means of a solar cell, or
connection to an external power source (e.g. mains supply).
NOTE 4 A type Z warning device could, for example, be normally powered from the I&HAS, and this power source
is also used to recharge its storage device.

At the end of the standby period, the storage device shall meet the operating time
requirements of 5.6.3.1.
For types X and Z, where loss of remote power supply causes the warning device to activate
(see Table 2) then the requirements of Table 8 do not apply, and the storage device shall only
meet the operating time requirements of 5.6.3.1.
5.6.3.3 Recharge rate
Type Y and Z warning devices shall be capable of supplying current at the appropriate voltage
to recharge the storage device equivalent to 80 % of that supplied by the storage device in
meeting the requirements of 5.6.3.1 and 5.6.3.2 within the periods as specified in Table 9.

5.6.3.4 Remote power monitoring
Where the warning device has a remote power source and this power source is lost, then the
warning device shall respond according to Table 2.
5.6.3.5 Remote power short circuit protection
Where the warning device has a remote power source it shall not be possible to discharge the
storage device through a short circuit applied to the remote power source connections.

5.7.1.2 Storage device monitoring
5.7.1.2.1 Storage device monitoring – Low voltage
The voltage of non rechargeable storage devices shall be monitored continuously. The
voltage of rechargeable storage devices shall only be monitored when the warning device is in
its standby condition.
A storage device low voltage fault occurs when the voltage of the storage device falls below
that specified by the warning device manufacturer. This voltage shall be greater than the
minimum voltage required to operate the warning device.
5.7.1.2.2 Storage device monitoring – Failure
Where the storage device is rechargeable, means shall be provided to determine whether the
storage device is no longer able to power the warning device e.g. by applying a load to the
storage device and monitoring the terminal voltage. These means shall not be achieved by
monitoring terminal voltage alone.
The maximum time period for detection of a storage device failure shall be 24 h.
5.7.2 Remote self test
Any remote test sequence shall not prevent the warning device from operating in accordance
with Table 2.
If a remote test is initiated, the warning device shall not remain in test mode for a period in
excess of 60 s.
An audible alarm or a tamper signal or message shall not be used to communicate the pass or
fail of a remote test request. One possible test sequence is shown in Annex B.
