2. Flexible Open Plan Office
Suspended plug-in luminaires fitted with Helvar Minisensor2 and
EL-si high frequency ballasts provide control of individual task lighting.
Combined with Helvar’s DIGIDIM system, multipoint control of the overall 1xx/2xx
office lighting is achieved. Office layout changes can be achieved by
moving the plug-in luminaires without any reprogramming or changes in
functionality. Alternatively existing luminaires can simply be reprogrammed
312
if the functionality of the area changes. Energy saving is achieved though
combinations of presence detection, constant light functionality and
individual dimming of each work area. Control of lights can be manual or
automated for ease of use and user comfort. 401/402

3. Energy Efficient Office Solution
Suspended luminaires, fitted with T5 tubes and Helvar EL-si high frequency
ballasts, give individual control of each up and down light. The desired light
1xx/2xx level combinations are easy to store and recall at the press of a button. In
addition to the energy saving benefits of electronic ballasts, DIGIDIM offers
further savings through:
• Presence detection that prevents unne-cessary
312
lighting of unused offices
• Constant light that reduces office lighting levels when
sufficient natural light exists.

5. Easy to use Meeting room
A simple Helvar DIGIDIM lighting control system and luminaires fitted with
EL-si DALI ballasts provide the perfect solution for this kind of application.
DIGIDIM enables lighting levels or scenes to be recalled at the touch of
1xx/2xx
the button via wall mounted panels or IR-remote controller. There is no
need for a separate IR-receiver as DIGIDIM panels have this inbuilt as a
standard. The IR-remote also allows simple reprogramming without the
303 need to consult a specialist.
One 5 core mains cable can be used for DALI and mains wiring, thus
reducing installation costs. Further system cost reductions can be achieved
by utilising the inbuilt DALI power supply of the ballasts.

LCD touch screen. This provides the simplicity and flexibility to control de-
vices independently or together at the touch of a single button. The display 401
is fully customisable with the possibilities to name each button and allow
multiple different control screens. The screen image can be customised to

7. Smart Store room Solution
Luminaires fitted with Helvar’s EL-si digital ballasts and Minisensor provide
the simple solution that can be delivered pre-programmed.
The PIR in the Minisensor will automaticly switch the lights on to any desired
303
level when someone enters the room. This light level can be set to achieve
maximum energy saving, lamp life and a reduction in lamp maintenance
requirements. If the room is unoccupied the lights will switch to a lower
level then off after a delay. This delay can be chosen to suit the frequency
Minisensor2
of use of the room. This maximises energy saving and increases lamp life
by avoiding unnesessary on/off switching of the lighting during the day.
