4 General considerations
This European Standard considers two different categories of warning device, remotely powered and
self-powered devices.
Self-powered warning devices are classified into one of four types, dependent upon the recharge
characteristics of the storage device and the source of recharge power. These four types are defined
in Table 9.
5 Requirements
5.1 Functional
5.1.1 Response
Depending upon the grade, warning devices shall have the functionality as defined in Table 1. Where
a function is provided, the warning device shall operate in accordance with the requirements of
Table 2.
NOTE Requirements for the interconnections are given in the specific interconnection standard(s).

The provision of a fault signal or message is not mandatory for all grades, see Table 1.
b
At least one of these actions shall occur at the warning device. For grade 3 and grade 4 warning devices, if
the loss of remote power source can be shown to be caused by a fault then a fault signal shall be generated,
otherwise a tamper signal shall be generated.
c
At least one of these actions shall occur at the warning device. For grade 3 and grade 4 warning devices, if
the loss of trigger command integrity can be shown to be caused by a fault then a fault signal shall be
generated, otherwise a tamper signal shall be generated.
d
The response to a remote test pass shall be different from the response to a remote test fail.
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 manufacturer’s specified operating voltage range.
Acoustic output levels as measured in accordance with Annex A, 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 For remote powered warning device, 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.
