1.0 Glossary of Terms
‘Digilite® DL500’ or ‘panel’
Refers to the Digilite® DL500 Emergency Lighting Supervisory Control Panel.
Downloading
Refers to the transfer of data from a PC to the Digilite® DL500.
Uploading
Refers to the transfer of data from the Digilite® DL500 to a PC.
Site-file
Refers to the site configuration data file that is stored in the Digilite® DL500, this file contains the data about
loop devices, panel settings, loop device text, group text, panel text and test duration and time. When this file
is uploaded using the Windows Configuration Tool any historic event logs are automatically appended to it.
Loop
The two wire power and data connections which the Digilite® DL500 uses to control and interrogate any
devices.
'Device' or 'Address'
A luminaire or interface connected to the Digilite® DL500 loop which can be controlled by and transmits data
to the Digilite® DL500.
Type
Each address on the Digilite® DL500 loop may be assigned a type by the PC commissioning software. The
type changes how the Digilite® DL500 controls and interprets data from the device.
Group
Individual luminaire addresses may be programmed into one of 28 groups. This is done to ensure that
emergency lighting coverage is maximised when luminaires are being tested (adjacent luminaires are usually
programmed into different groups). Testing is performed on a group basis.
Maintained luminaire
A light fitting which is always illuminated, either from a local mains supply, or from a backup supply if the
local mains supply fails.
Non-maintained luminaire
A light fitting which only illuminates using a backup supply when the mains supply to it is disconnected.
Disablement
When a device, or group is disabled it is prevented from entering test mode and cannot generate faults, or
failed tests.
Sub Circuit
Some Digilite® DL500 fittings can be set to monitor the state of their local mains connection, and report this
back to the Digilite® DL500. The mains supply monitored by these fittings may differ from the mains
supplying the Digilite® DL500 itself, and is termed a 'Sub Circuit'.
Historic Event log
A chronological record of salient events on the system (e.g. group tests, luminaire failures etc).
Central system
A Central Battery or Static Inverter system which uses a centralised power source to feed slave lighting, as
opposed to the lighting having its own local battery.
Slave Interface
An interface designed to monitor the status of a lamp, usually used on central systems. This interface
generally has no control functionality.
