a The provision of a fault signal or message is not mandatory for all grades, see Table 1.
b At least one of these actions should 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.
c The response to a Remote test pass shall be different to the response to a Remote test fail.

4.1.2 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 100 dB(A) at 1 m from the mounting surface of
the warning device throughout the manufacturers specified operating voltage range. Peak
measurements shall be taken 1 m from the warning device at 30° intervals in the horizontal plane.
Each individual reading shall not be less than 95 dB(A), and 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 of a warning device may be subject to variation depending on local or national requirements.

4.1.3 Timing
A trigger command exceeding 400 ms shall be processed by the warning device.
A warning device shall commence sound activation within 1 s of receiving a valid trigger command to
do so. It shall cease sound activation within 1 s of receiving a valid trigger command to do so.
NOTE 1 This instruction may be the 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 2 Where applicable this requirement may be achieved by the CIE.
NOTE 3 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 & 2, within 10 s of the fault occurring.
A response to local test fail according to Tables 1 & 2, shall occur within 10 s of detection of the fault.
4.2 Tamper
4.2.1 Protection
All component parts shall be housed in an enclosure meeting the impact requirements of the
appropriate grade given in Table 3.
Provision shall be made to allow adequate fixing of the enclosure to the mounting surface.

The cover of the enclosure shall be secured with one or more screws or bolts or alternatively by a
mechanical lock. The cover of the enclosure shall be opened only with the use of one or more keys or
suitable tools.
It shall not be possible to gain access to any electrical connections, or elements providing adjustment,
without first generating a tamper signal or message.
It should not be possible to introduce a rod, as defined in Table 4, when the unit is mounted normally,
such that the operation of the warning device could be adversely affected. Damage should not be
caused that would be visible to a person of normal eyesight viewing at a distance of 2 m with the
warning device illuminated at a level of 2 000 lx.

4.2.2 Detection
The tamper detection requirements for warning devices relative to the security grade are given in
Table 5.
Opening the warning device enclosure by normal means shall generate a tamper signal or message.
The housing shall not permit the introduction of a tool of dimension as specified in Table 4 and type as
specified in EN 60529, to defeat the tamper detection.
Attempts to remove the warning device from its mounting surface for a distance defined in Table 6 in a
perpendicular direction shall generate a tamper signal or message according to Table 5.
It should not be possible to defeat the removal from mounting detection in grade 4 by sliding a 1 mm
thick blade 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 5, when a hole of 4 mm is made in the
enclosure.
