Lighting control panels can contain relays, controllers, communication interfaces, power supplies, input/output modules, protection devices, and other components required by the approved lighting control architecture.

Panel configuration is coordinated with the number and type of controlled circuits, connected loads, control method, communication protocol, zoning requirements, electrical distribution system, and project specifications.

Dimming Control

Dimming systems allow lighting output to be adjusted according to the requirements of each space. Dimming can support operational flexibility, architectural scenes, visual comfort, and energy-management strategies where compatible luminaires and LED drivers are installed.

The selected dimming technology must be coordinated with the luminaires, LED drivers, controllers, and lighting control equipment. Compatibility should be verified before installation and commissioning.

DALI Lighting Control

Digital Addressable Lighting Interface (DALI) can be used where digitally addressable lighting control is required for individual luminaires or groups of luminaires.

A DALI-based solution can provide functions such as switching, dimming, grouping, scene control, status monitoring, and other functions supported by the selected DALI devices and control system.

DALI system design requires coordination of control devices, bus topology, addressing, bus power supplies, gateways, luminaires, LED drivers, interfaces, and commissioning requirements.

Occupancy & Motion Sensors

Occupancy and motion sensors can automatically control lighting according to the presence or absence of people within designated areas.

Sensor locations, detection coverage, mounting height, sensitivity, time delay, and operating mode are coordinated with the intended use and physical characteristics of each space.

Daylight Sensors

Daylight sensors can be used to adjust artificial lighting according to the available natural light where daylight-responsive control is included in the approved lighting strategy.

The system can switch or dim selected lighting zones according to sensor readings and programmed control parameters, subject to the capabilities of the installed luminaires and control equipment.

Photocell Control

Photocells can provide automatic control of external lighting or other designated lighting circuits according to ambient light conditions.

Photocell operation can be coordinated with time schedules, astronomical clocks, manual overrides, or centralized lighting controls according to project requirements.

Time Scheduling

Scheduled control can be applied to common areas, external lighting, parking areas, circulation spaces, landscape lighting, and other areas with defined operating periods.

Scene Control

Scene control allows predefined lighting levels or combinations of lighting circuits to be recalled for different activities and operating conditions.

Scene control can be applied in meeting rooms, auditoriums, reception areas, hospitality spaces, multipurpose rooms, architectural areas, and other applications requiring different lighting conditions.

Local Control Devices

Local control can include wall switches, push buttons, scene-control plates, touch panels, dimmer controls, key switches, and other user interfaces supported by the selected system.

Local controls are coordinated with the required operating philosophy, architectural finishes, accessibility, lighting zones, and centralized control functions.

Manual Override

Manual override functions can be provided where operators require direct control of designated lighting circuits or zones independently of normal automatic commands.

Override operation and priority should be defined within the approved control philosophy to avoid conflicts between local controls, schedules, sensors, and centralized commands.

Indoor Lighting Control

Indoor lighting control can be applied to offices, corridors, meeting rooms, reception areas, public spaces, residential areas, hospitality spaces, service areas, and other internal zones.

The appropriate control strategy depends on occupancy, daylight availability, required lighting levels, operational schedules, user requirements, and the capabilities of the installed lighting equipment.

External Lighting Control

External lighting control can include roads, parking areas, pedestrian walkways, building surroundings, landscape areas, architectural façades, and other exterior lighting applications.

Depending on project requirements, external lighting can be controlled using photocells, astronomical time schedules, contactors, lighting control panels, programmable controllers, or centralized control systems.

Road & Parking Area Lighting

Road and parking lighting circuits can be divided into suitable control zones and operated according to schedules, photocells, operational requirements, or centralized commands.

Control arrangements are coordinated with the electrical distribution system, lighting panel boards, circuit ratings, contactors or control modules, and approved lighting design.

Walkway & Landscape Lighting

Walkway and landscape lighting control can be configured for pedestrian routes, gardens, trees, planting areas, decorative elements, and other external landscape applications.

Lighting zones can be programmed according to operating periods, architectural requirements, daylight conditions, and facility-management requirements.

Façade & Architectural Lighting

Architectural and façade lighting may require multiple lighting groups, dimming levels, scenes, schedules, or other control functions depending on the approved lighting concept.

Control equipment is coordinated with luminaires, drivers, electrical distribution, architectural requirements, and environmental conditions.

Water Feature Lighting Control

Lighting associated with fountains, pools, and other water features can be integrated into the lighting control system where included within the approved project scope.

Electrical and control equipment for these applications is coordinated with the lighting equipment, environmental conditions, electrical protection, and other systems associated with the water feature.

BMS Integration
