Common dimming via a pull cord. Provided with flex and plug.

Integral light sensor for constant lighting/movement detector and IR receiver. Provided with flex and plug.

Automatic on/off function via occupancy sensor. Adjustable switch-off delay 5 s - 30 min. Switching-off for lighting levels of 50-20,000 lux or inactivity.

DALI (Digital Adressable Lighting Interface)
Standardised digital protocol for lighting control. DALI can conveniently be combined with other control systems.

Non-addressable digital control. In the DSI system the control information is transmitted to the electronic ballast via a non-addressable digital signal. All luminaires connected to the system are controlled in the same way, regardless of the distance between the control unit and the luminaire. Also provides the opportunity for control of light sources with different outputs. The lighting is turned on and off with a digital control command. The luminaires are live even when turned off. Depending on the type of light source, the minimum level is 1%, 3% or 10%.

Stepless control of luminance.

Lighting control system
System which controls individual luminaire groups and/or whole systems.

Electronic ballast for dimming (HF)
Ballast which permits dimming via a separate control circuit.

Digital lighting control system
Control signals between the units are transmitted in the form of digital commands. Commands in digital form are less sensitive to interference than analogue systems.

Analogue control system
An analogue system is commonly based on 1-10V DC between the control unit and the luminaire. These systems control either the voltage or the resistance of the control circuit. The length of the control wires may affect the control result.

Phase control
A system based on control of the lighting level via 230 V (e.g. by using a momentary wall switch or an integral pull switch in the luminaire). Best known under the name SwitchDim. The system requires a 4-conductor connection to the luminaire if a wall switch is to be used.

Addressed control
The units in the system can be individually addressed enabling them to be controlled independently of each other. This system requires the DALI digital protocol.

Multi-channel control
An installation can be divided into several groups or channels which can be controlled independently of each other or together.

Lighting scenes
A setting for a lighting situation/arrangement which can be simply retrieved on demand.

Constant lighting level
The system attempts to maintain luminance within a desired area (e.g. under the luminaire) at a constant level. The lighting level of the artificial lighting will be affected by incident daylight. Used to save energy.

Occupancy detector
A detector which detects a person's heat radiation. A movement within the detector’s monitoring area will turn on the luminaire. An integral timer turns off the luminaire if no movement occurs within the sensor’s detection area.

IR receiver
Receives signals from the remote control and passes them on to the system. Usually integrated in a wall panel or multisensor.

A sensor which usually comprises the functions of constant lighting level, occupancy detector and IR receiver.
