Automate lighting of surroundings of a building

Value proposition

Main drivers

• To light up the surroundings of a public or tertiary building when the natural brightness threshold becomes insufficient.
• To  switch off automatically when daylight is sufficient again.

Value proposition

• Up to 15% energy saving by automatically extinguishing lighting when it is not necessary.
• Automation ensures major energy savings, increased comfort and enhanced safety.

Differentiation factors

• The IC 100 twilight switch is the ideal product for problem-free management of these needs. Once installed and its threshold set, it will automatically switch on and turn off the lighting at the right time. A built-in time delay avoids untimely closing or tripping during undesired transient brightness conditions.

Architecture

Main Energy Efficiency characteristics

• The solution is to set the lighting operation threshold on the IC 100 twilight switch according to the external brightness measured by the wall-mounted cell:
• The photoelectric cell detects low brightness, causes closure of IC 50 contact and ensures lighting
• The IC 100 monitoring light comes on when brightness threshold is reached and switches off lighting
• Time delay on closing and breaking of contact: 10 seconds
• Setting the tripping threshold from 2 to 100 lux.
