INTRODUCTION

Emergency lighting systems are a safety related product; their correct performance can only

be assured by systematic testing and maintenance. Conventional techniques for testing are

reliant upon manual testing procedures, and are highly susceptible to neglect. These

limitations of conventional techniques can be overcome by automating the testing process. It

is essential that automatic testing systems for emergency luminaires schedule tests reliably,

and provide timely notification of failures or degradation of performance.

Automatic test systems (ATS) will still require manual intervention to correct faults when they

are identified, and procedures should be put in place for such intervention. These systems

provide information to assist users to manage risk on their premises.

Automatic test systems for emergency escape lighting assist the operator of the building by

showing the results of tests that will have been made at prescribed intervals, without

disrupting any other electrical services. It is essential that the notification of failures or

reduction in performance be given at the earliest opportunity to enable the emergency escape

system to be restored to full operation.

The automatic test system will provide those responsible for an emergency lighting installation

with information to enable them to ensure that the installed luminaires operate correctly when

required.

The automatic test system may be part of a building management system (BMS) for making

the emergency lighting tests; this standard would only apply to the emergency lighting testing

part of a BMS.

A visual check of system components and indicators should be included in the routine of

safety staff. This check should be made regularly to ensure that the emergency luminaire is

present and intact, with lamps and indicators working and visible i.e. not obscured, covered or

painted.

4 Requirements
4.1 Safety, construction and installation instructions

All parts of the ATS shall conform to the requirements of IEC 60598-1 and IEC 60598-2-22

where these are appropriate.

NOTE 1 Guidance for the appropriate application of standards for typical systems is provided in Annex A.

The design and construction of the ATS shall ensure that only authorized personnel can

change the test duration and the frequency of tests.

The manufacturer shall include installation instructions for the ATS, which shall define any

limits of the size and compatibility of the ATS.

In the installation instructions, manufacturers shall advise the type of emergency luminaires

for which the ATS is designed.

Compliance is checked by inspection of the manufacturer’s instructions and/or of the

instruction sheet provided by the manufacturer.

The ATS shall be classified and marked according to one of the type stated in Annex B.

NOTE 2 Test circuit components may be installed within or adjacent to either self-contained or centrally powered

luminaires. Additional components may be located in a remote panel.
4.2 Monitoring of the timing circuit

In all ATS types (see Annex B), any failure of the progress of the test sequence of the ATS

shall be indicated locally on the luminaire and/or on the remote panel as applicable to the

ATS type.

NOTE The monitoring of the timing circuit is essential as the duration of testing periods and the intervals between

them need to be ensured and maintained.

This failure shall be tested by simulating a fault that interrupts the progress of the test

sequence or any other procedure that can be agreed with the system designer/manufacturer

and the test laboratory to demonstrate compliance with this clause, and checking that the

failure is indicated locally on the luminaire and/or on the remote panel as applicable to the

ATS type.

Compliance is checked by testing a sample according to the instructions provided by the

manufacturer.
4.3 Functional requirements

NOTE The tests of 4.3 and 4.4 should be carried out before the tests of Clause 5.

4.3.1 The automatic test system (ATS)

The ATS shall check the functional operation of the emergency lighting luminaires and

associated power supplies, at intervals and for the duration specified in Clause 5, to identify

any faults that would impair their operational duty. Any faults shall be indicated or reported

---------------------- Page: 11 ----------------------
– 10 – 62034 © IEC:2012

within 24 h after their detection. For types P, ER, PER and PERC, verification for a fully

loaded system may be made by extrapolation of the polling rate measured on the individual

unit.
NOTE Types P, ER, PER and PERC are defined in Annex B.
Compliance is checked by inspection and prescribed test (see Clause 5).
4.3.2 Emergency battery supply

The test system shall check and indicate if the emergency battery supply has failed.

Compliance is checked by disconnecting the battery during the test sequence – a fault shall

be indicated within the test period.
4.3.3 Lamps tested in the emergency mode

The test system shall check that any changeover device, where fitted, has powered the lamp

from the emergency power supply.

NOTE The full load from the battery is equivalent to the maximum discharge load current of the circuit, excluding

the starting period.
Compliance is checked as follows:

• if the charging current to the battery is higher than 15 % of the full load, the charger shall

be disconnected during the test;

• if the charging current is between 5 % and 15 % of the full load, the charger shall be

compensated during the test;

• if the charging current is less than 5 % of the full load, the charger should be ignored

during the test.
4.3.4 Maintained luminaires tested in emergency mode and in normal mains
condition

For maintained luminaire that do not have a changeover device, the test system shall check

that the lamp operates correctly in both the normal mains supply and failed supply conditions.

For maintained luminaries with a changeover device, test shall be carried out according to

4.3.3 with the monitoring of the battery current or output voltage to check the changeover.

Compliance is checked by inspection of the test system when the maintained lamps are

operating.
4.4 System integrity
4.4.1 Protection against system part failures and faults

Any single fault or part-failure that occurs in the ATS, or within one of the system parts, shall

not affect the emergency operation of the ATS, in accordance with the requirements of 4.4.2

to 4.4.7.
Compliance is checked by inspection and the requirements of 4.4.2 to 4.4.7.
---------------------- Page: 12 ----------------------
62034 © IEC:2012 – 11 –
4.4.2 Intercommunications failure

Any failure of intercommunication between the parts of ATS system, as defined in 3.3 and 3.4,

shall not inhibit the emergency operation of the luminaires connected to the ATS, or initiate an

unwanted test. Furthermore, in the case P, ER, PER and PERC ATS types (see Annex B),

any failure of intercommunication between ATS parts shall be indicated as a fault on the

remote panel within 24 h of the failure occurring.

For this test, the communication shall be interrupted by the appropriate means (according to

the manufacturer’s instructions). The following checks are then made:
– no unwanted test is initiated;

– the emergency operation of the luminaires operates if the normal supply is switched off;

– the failure of the interconnection between ATS parts is indicated as a fault on the remote

panel within 24 h.
NOTE Subclauses 22.3.18 and 22.3.21 of IEC 60598-2-22 are to be considered.
4.4.3 System interconnection

The operation of luminaires in the emergency mode shall not be affected by any faults in the

wiring of the interconnections of the ATS, including a short circuit, contacts to earth or an

interruption in the wiring of the ATS supply or communications wiring. No unwanted test shall

be initiated. The test shall only operate at correct times; other tests would put the system’s

emergency duty at risk.
Compliance is checked by simulation of these wiring faults to the ATS.

NOTE Short circuit connections between supply and communications wiring are not included in the test if they are

separa
