Rest mode ON/OFF 2 0 = rest mode off
1 = rest mode on
Reset lamp 0 = no effect
1 = reset
Restore "ex-works" status 0 = no effect
1 = restore status
Brightness value [0...100] %
2 Can only be used if EIB bus voltage is present even in the case of lack of mains power.
A variable, "Result of executing the last command", is produced following reception
of a command giving the result of executing the command.
Code
Result of executing 0 = negative
the last command 1 = positive
7. LAMP OPERATING MODE
Maintained lamps can operate in both Maintained and Not-Maintained mode.
The operating mode is selected using the "Select operating mode" command.
The object of the "Maintained/Not-Maintained Mode" communication shows the
current operating mode as coded in the following table:
Operating mode Code
Maintained/ 0 = Not-Maintained
Not-Maintained Mode 1 = Maintained
In the case of a reset the lamp is automatically set to not-maintained operating mode.
8. OPERATING STATUS DESCRIPTION
The lamp can be in one of the operating statuses described through the variables
according to the coding shown in the following table.
Status Code
Status: test in progress 0 = false
(functional
1 = true
Status: emergency 3 0 = false
operating
1 = true
Status: rest mode 3 0 = false
1 = true
Status: low absorption 3 0 = false
1 = true
3 Updated if the EIB power supply is still present in the case of a mains power failure
If the lamp is in none of the statuses described, it is in Normal operating mode.
The enable status of the inhibition function is signalled through the "Inhibition mode
enable status" variable as shown in the following table.
Status Code
Inhibition mode 0 = disabled
enable status 1 = enabled
When the inhibition function is active, in the case of a mains power failure, the lamp
does not go into emergency status but goes to low absorption status: all commands
are ignored in this case.
9. FUNCTIONAL TEST
The functional test is used to detect possible light source malfunctions. EIB command
"Run functional test" must be used for running the test. The functional test is run by
putting the lamp in the same conditions that it would be in when it is in emergency:
the internal power supply unit is switched off and the power supplied by the battery
used. The functional test lasts approximately 180 seconds and is only run if:
• mains power is present
• the battery is sufficiently charged (to drive the lamp throughout the test)
• Inhibition mode is disabled
EIB variable "Status: test in progress" takes the value of 1 while the test is being run.
On completion of the test run the possible negative result is given in EIB variable
"Light source alarm" that takes the value of 1, while EIB variable "Status: test in
progress" is reset.
If in maintained mode the lamp makes a check of the light source at periodic intervals
but without disconnecting the power supply unit from the mains. In this case, too, a
possible fault in the light source is signalled through the "Light source alarm" variable.

10. BATTERY TEST
The battery test is used to check whether the battery is able to keep the lamp alight
for the declared period of autonomy in the absence of mains power. A functional test
is run at the start of the test to check whether the light source is in good condition in
order to prevent the test results from being falsified by the fact that power absorption
of the battery is greater when the light source is not in good condition. The battery
test is not run if the functional test gives a negative result.
EIB command "Run battery test" must be used for running the test.
The battery test is only run if:
• mains power is present
• the light source is in good condition (functional test OK)
• the battery is sufficiently charged to drive the lamp throughout the test
• inhibition mode is disabled
Should the latter condition not be respected, the "Run Battery test" command will not
be accepted and the "Result of executing last command" variable takes the value of 0.
Variable "Status: test in progress" takes the value 1 while the test is being run. On
completion of the test run variable "Status: test in progress" takes the value 0 while
the result is given in variable "Battery alarm". In any case the lamp carries out a
continuous check of the battery that is used to discover whether the battery is
disconnected. The result of the test is given in variable "Battery alarm .
Should the result of the battery test be negative it is recommended to repeat the
test at least once after having waited the specified recharge time before replacing
the battery.

11. ALARM DESCRIPTION

The lamp generates alarm signals when it detects faults and/or malfunctions both
following requested tests and in result of the self-diagnosis checks that are always
and anyway carried out by the lamp. The alarm signals and relative code are shown in
the following table:
Alarm Code
Light source alarm 0 = false
1 = true
Battery alarm 0 = false
1 = true
12. STATUS BYTE
The information relative to the operating mode, lamp status and alarms is also made
available via the KNX/EIB bus through a summary status byte structured as follows:
Bit 0 : Maintained/Non-Maintained mode
Bit 1 : Light source alarm
Bit 2 : Battery alarm
Bit 3 : Status: test in progress
Bit 4 : Status: emergency
Bit 5 : Status: rest mode
Bit 6 : Status: low absorption
Bit 7 : Inhibition mode enable status
The coding of the information contained in the "Status Byte" is identical to that of the
same information made available via bit type communication items.
13. BATTERY CHARGE PERCENTAGE
The lamp measures the voltage of the battery, supplying its value through the
following variable:
Measurement Code
Battery charge percentage [0..100]%
14. RATING PLATE DATA
The lamp makes the following rating plate data available on the EIB bus:
Rating plate data item Code
Lamp power [0.. 255]
15. LAMP BEHAVIOUR IN THE CASE OF A RESET
Following the reception of a reset command, if mains power is present, the lamp
returns to Normal operation, in Not-Maintained operating mode. Possible alarms are
deleted.
The above also applies if the reset is due to a watchdog timeout or a power down. The
reset command can be used to stop execution of a possible test in progress.
16. REST AND INHIBITION MODE
Rest mode and inhibition mode can be used should it be necessary to carry out
maintenance operations, to prevent the lamps from going into emergency when the
mains power is down. The conditions of use of the two modes are given in the
following table:
Rest mode The rest status input and output commands can only be carried out
if the lamp is in emergency status (mains power down). This
command can only be used if the EIB power supply continues to
be present including in the case of the mains power being down.
