INTRODUCTION
This first edition of IEC 62386-202 is published in conjunction with IEC 62386-101 and
IEC 62386-102. The division of IEC 62386 into separately published parts provides for ease
of future amendments and revisions. Additional requirements will be added as and when a
need for them is recognized.
This International Standard, and the other parts that make up IEC 62386-200 series, in
referring to any of the clauses of IEC 62386-101 or IEC 62386-102, specify the extent to
which such a clause is applicable and the order in which the tests are to be performed; The
parts also include additional requirements, as necessary. All parts that make up the
IEC 62386-200 series are self-contained and therefore do not include references to each
other.
Where the requirements of any of the clauses of IEC 62386-101 or IEC 62386-102 are
referred to in this International Standard by the statement "The requirements of IEC 62386-
1XX, clause “n” apply”, this sentence is to be interpreted as meaning that all requirements of
the clause in question of Part 101 or Part 102 apply, except any which are inapplicable to the
specific type of lamp control gear covered by this Part 202.
All numbers used in this International Standard are decimal numbers unless otherwise noted.
Hexadecimal numbers are given in the format 0xVV, where VV is the value. Binary numbers
are given in the format XXXXXXXXb or in the format XXXX XXXX, where X is 0 or 1; 'x' in
binary numbers means 'don't care'.

The following referenced documents are indispensable for the application of this document.
For dated references, only the edition cited applies. For undated references, the latest edition
of the referenced document (including any amendments) applies.
IEC 62386-101:2009, Digital addressable lighting interface – Part 101: General requirements
– System
IEC 62386-102:2009, Digital addressable lighting interface – Part 102: General requirements
– Control gear
3 Terms and definitions
For the purposes of this document, the terms and definitions given in Clause 3 of
IEC 62386-101:2009 and Clause 3 of IEC 62386-102:2009 apply, together with the following.
3.1
normal mode (for self-contained emergency control gear)
mode in which mains supply is available, with the battery charged or charging
3.2
emergency mode (for self-contained emergency control gear)
mode in which mains supply has failed and whilst the control gear is powered by the battery
until deep discharge point
3.3
rest mode (for self-contained emergency control gear)
mode in which the lamp is intentionally off whilst the control gear is powered by the battery
3.4
inhibit mode (for self-contained emergency control gear)
mode in which the control gear is powered from the mains but prevented from going into
emergency mode in the event of mains failure
3.5
extended emergency mode (for self-contained emergency control gear)
mode in which the control gear continues to operate the lamp in the same way as in
emergency mode for the programmed prolong time after the restoration of the mains supply

62386-202 © IEC:2009 – 9 –
3.6
function test
test to check the integrity of the circuit and the correct operation of a lamp, a changeover
device and the self-contained battery
3.7
duration test
test to check if the self-contained battery supplies the system within the limits of rated
duration of emergency operation
3.8
hardwired inhibit
optional additional input of the control gear which prevents the control gear from going into
the emergency mode.
NOTE The hardwired inhibit input is specified by the manufacturer. The state of the switch may be “active” or
“inactive”.
3.9
prolong time
time the extended emergency mode will last after restoration of the mains supply
3.10
non-maintained control gear
control gear which operates the lamp only in emergency mode or test mode and supports
neither arc power control commands nor corresponding configuration commands
3.11
maintained control gear
control gear which operates the lamp always, no matter whether the mains is present or not,
but which supports neither arc power control commands nor corresponding configuration
commands
3.12
switched maintained non-dimmable control gear
control gear with physical minimum level equal to 254 (100 %)
NOTE If the mains is present, this type acts like a standard dimmable device with its minimum level set to 254.
Therefore this type supports all arc power commands and corresponding configuration commands defined in
Part 102. Because of the definition of the physical minimum level, all arc power commands will result in
'no reaction', 'lamp on' or 'lamp off' only – depending on the definition of the actual command.
3.13
switched maintained dimmable control gear
emergency control gear with a physical minimum level below 254 (100 %)
NOTE If the mains is present, this type acts like a standard dimmable device. Therefore this type supports all arc
power commands and corresponding configuration commands defined in Part 102.
3.14
hardwired switch
optional additional input of the control gear to switch the lamp on and off in normal mode
NOTE The hardwired switch input is specified by the manufacturer. The state of the switch may be “on” or “off”.
3.15
integral emergency control gear
lamp control gear which forms a non-replaceable part of an emergency luminaire and which
cannot be tested separately from the luminaire

– 10 – 62386-202 © IEC:2009
3.16
deep discharge
situation in which the lamp can no longer be powered by the battery because the battery
voltage has fallen to the lower battery threshold as defined by the cell manufacturer
4 General
The requirements of Clause 4 of IEC 62386-101:2009 and Clause 4 of IEC 62386-102:2009
shall apply.
5 Electrical specifications
The requirements of Clause 5 of IEC 62386-101:2009 and Clause 5 of IEC 62386-102:2009
shall apply.
6 Interface power supply
The requirements of Clause 6 of IEC 62386-101:2009 and Clause 6 of IEC 62386-102:2009
shall apply if the control gear has an integral power supply.
7 Transmission protocol structure
The requirements of Clause 7 of IEC 62386-101:2009 and Clause 7 of IEC 62386-102:2009
shall apply.
8 Timing
The requirements of Clause 8 of IEC 62386-101:2009 and Clause 8 of IEC 62386-102:2009
shall apply.
9 Method of operation
9.1 Logarithmic dimming curve, arc power levels and accuracy
The requirements of Subclause 9.1 of IEC 62386-102:2009 shall apply only if the emergency
control gear supports arc power commands and the corresponding configuration commands.
9.2 Power-on
The requirements of Sublause 9.2 of IEC 62386-102:2009 shall apply if the emergency control
gear supports arc power control commands and where “power-on” means the application of
mains supply once the battery supply is established.
Where "power-on" means application of the mains power, the control gear shall react properly
to commands no later than 0.5 s after power-on.
Where “power-on” means application of only the battery supply, the control gear shall either remain in
a power-down state or go into emergency mode or rest mode. If the control gear goes into emergency
mode or rest mode it shall react properly to commands no later than 5 s after power-on.
If mains power is applied to the control gear when it is completely powered off, it shall go into
normal mode.
NOTE 1 The battery supply is normally permanently connected to the control gear

62386-202 © IEC:2009 – 11 –
NOTE 2 Low power clock circuits may take several seconds to start.
NOTE 3 It follows that the power-on time of emergency control gear may not be well synchronised with the power-
on time of other control gear in the same system.
NOTE 4 The application of mains power to gear running on battery power is not a power-on event, but may
change the mode of operation of the control gear as described in 9.9 below.
9.3 Interface-failure
If the control gear supports arc power commands and the corresponding configuration
commands, then the requirements of Subclause 9.3 of IEC 62386-102:2009 shall apply, when
the control gear is in normal mode. Otherwise, an interface failure as described in Subclause
9.3 of IEC 62386-102:2009 shall have no effect on the arc power level.
NOTE Although the requirements of Subclause 9.3 of IEC 62386-102:2009 state that on restoration of the idle
voltage the control gear shall not change its state, in practice there may be an approximately simultaneous change
of state if the restoration of the interface idle voltage coincides with the restoration of mains power.
9.4 Min and max level
If the control gear supports arc power commands and the corresponding configuration
commands, then the requirements of Subclause 9.4 IEC 62386-102:2009 shall apply when the
control gear is in normal mode.
The EMERGENCY LEVEL shall not be affected by the MIN LEVEL and MAX LEVEL settings.
The MIN LEVEL and MAX LEVEL shall only affect the arc power level during normal mode;
they have no relation with and shall therefore not be linked in any way to the
EMERGENCY LEVEL, EMERGENCY MIN LEVEL and EMERGENCY MAX LEVEL.
NOTE 1 If commands affecting the EMERGENCY LEVEL are supported, then (because of the provisions of 11.2)
programming an EMEGENCY LEVEL above the EMERGENCY MAX LEVEL or below the EMERGENCY MIN LEVEL
causes the EMERGENCY LEVEL to be set to the EMERGENCY MAX LEVEL or EMERGENCY MIN LEVEL.
NOTE 2 PHYSICAL MIN LEVEL is the manufacturer-fixed minimum level for mains operation and is not
necessarily related to any emergency light level.
NOTE 3 Figure 1 illustrates the relationship of the various light level definitions.

9.5 Fade time and fade rate
If the control gear supports arc power commands and the corresponding configuration
commands, then the requirements of Subclause 9.5 of IEC 62386-102:2009 shall apply.
9.6 Reaction to commands during error state
If the control gear supports arc power commands and the corresponding configuration
commands, then the requirements of Subclause 9.6 of IEC 62386-102:2009 shall apply when
the control gear is in normal mode.
9.7 Behaviour during lamp preheating and lamp ignition time
If the control gear supports arc power commands and the corresponding configuration
commands, then the requirements of Subclause 9.7of IEC 62386-102:2009 shall apply when
the control gear is in normal mode.
9.8 Memory access and memory map
The requirements of Subclause 9.8 of IEC 62386-102:2009 shall apply.

9.10 Function and duration test
The control gear shall be able to perform two kinds of tests, a function test and a duration
test. The emergency status byte, failure status byte and duration test result byte shall give an
indication of the progress and results of these tests.
Automatic testing is an optional feature, the presence of which shall be indicated in bit 3 of
the FEATURES byte.
NOTE The ability to perform duration tests and function tests is not an optional feature, the commands to start
and stop tests being supported by all self-contained emergency control gear. It is the automatic scheduling of such
tests which is optional.
If automatic testing is supported, the gear shall be capable of starting function tests and
duration tests according to a schedule defined by the functionality required for commands 234
to 237, and illustrated in annexes A.5 and A.6.

11 Definition of commands
11.1 Arc power control commands
If the control gear supports arc power commands, then the requirements of Subclause 11.1 of
IEC 62386-102:2009 shall apply, except that if a hardwired switch is fitted then arc power
commands shall be obeyed only if the hardwired switch is on. If the hardwired switch is fitted
but switched off, no arc power commands shall be executed.
Commands affecting the Arc Power Level shall only be processed in normal mode or inhibit
mode. Likewise, the control gear shall take account of the state of the hardwires switch only
when in normal mode or inhibit mode.
NOTE This behaviour is similar to that of a non-emergency control gear with switched mains connected.
11.2 Configuration commands
If the control gear supports arc power commands, then the requirements of Subclause 11.2 of
IEC 62386-102:2009 shall apply.
The following commands shall have no effect upon control gear which does not support arc
power commands:
Command 33: YAAA AAA1 0010 0001 "STORE ACTUAL LEVEL IN THE DTR"
Command 42: YAAA AAA1 0010 1010 "STORE THE DTR AS MAX LEVEL"
Command 43: YAAA AAA1 0010 1011 "STORE THE DTR AS MIN LEVEL"
Command 44: YAAA AAA1 0010 1100 "STORE THE DTR AS SYSTEM FAILURE
LEVEL"
Command 45: YAAA AAA1 0010 1101 "STORE THE DTR AS POWER ON LEVEL"
Command 46: YAAA AAA1 0010 1110 "STORE THE DTR AS FADE TIME"
Command 47: YAAA AAA1 0010 1111 "STORE THE DTR AS FADE RATE"
Commands 64 – 79: YAAA AAA1 0100 XXXX "STORE THE DTR AS SCENE"
Commands 80 – 95: YAAA AAA1 0101 XXXX "REMOVE FROM SCENE"
All other commands defined in Subclause 11.2 of IEC 62386-102:2009 shall affect all control
gear in the ways defined in that clause.
11.3 Query commands
The requirements of Subclause 11.3 of IEC 62386-102:2009 shall apply with the following
exceptions:
11.3.1 Queries related to status information
Command 144: YAAA AAA1 1001 0000 "QUERY STATUS"
The answer shall be the following "STATUS INFORMATION" byte:
bit 0 Status of control gear; "0" = OK
bit 1 Lamp failure; "0" = no lamp failure
NOTE The emergency control gear may not be able to detect an emergency lamp failure without performing a
function test or a duration test or entering emergency mode.
bit 2 Lamp powered by emergency control gear; "0" = Lamp not powered by emergency
control gear.
NOTE The emergency control gear may not be able to provide information about the state of the lamp when in
normal mode.
– 16 – 62386-202 © IEC:2009
bit 3 If the emergency control gear supports arc power commands, the value of this bit is as
defined in Subclause 11.3.1of IEC 62386-102:2009; otherwise this bit shall be cleared.
bit 4 If the emergency control gear supports arc power commands, the value of this bit is as
defined in Subclause 11.3.1of IEC 62386-102:2009; otherwise this bit shall be cleared.
bit 5 Query: "RESET STATE"? "0" = "No"
bit 6 Query: Missing short address? "0" = "No"
bit 7 If the emergency control gear supports arc power commands, the value of this bit is as
defined in Subclause 11.3.1of IEC 62386-102:2009; otherwise this bit shall be cleared.
Command 146: YAAA AAA1 1001 0010 "QUERY LAMP FAILURE"
Ask if there is a lamp problem at the given address. The answer shall be "Yes" or "No".
NOTE The emergency control gear may not be able to detect an emergency lamp failure without performing a
function test or a duration test or entering emergency mode.
Command 147: YAAA AAA1 1001 0011 "QUERY LAMP POWER ON"
If the lamp is powered by the emergency control gear, then the answer shall be “Yes”.
Otherwise the answer shall be “No”.
NOTE The emergency control gear may not be able to provide information about the state of the emergency lamp
when in normal mode.
Command 148: YAAA AAA1 1001 0100 "QUERY LIMIT ERROR"
If the control gear supports arc power commands, then the requirements of Subclause
11.3.1of IEC 62386-102:2009 apply. Otherwise the answer is “No”.
Command 153: YAAA AAA1 1001 1001 "QUERY DEVICE TYPE"
Answer shall be 1.
11.3.2 Queries related to arc power parameter settings
NOTE It follows from the requirements of Subclause 11.2 that if the control gear does not support arc power
control commands, the replies to these queries are the default values of the corresponding variables, as listed in
Clause 10 of IEC 62386-102:2009.
11.3.4 Application extended commands
Every control command (224 to 232 and 254) and configuration command (233 to 240) shall
be received a second time within 100 ms (nominal) before it is executed in order to reduce the
probability of incorrect reception. No other commands addressing the same control gear shall
be sent between these two commands, otherwise the first such command shall be ignored
and the respective control or configuration sequence shall be aborted.
Command 272 shall be received before the two instances of the application extended
configuration/control command, but not between them (see Figure 3).
