Introduction

Passageways have numerous switches and are broadly distributed, they are often turned on mindlessly, and left to remain on after using, they are hard to manage; thus, they require a better way to manage them.

Daylit Hallways

Hallway is brightly lit by natural light and yet the artificial lights are on.

 

Elevator Lobbies

No one is using them, but they are lit just the same.

 

Stairwells

The lights are kept on all 24 hours of the day.

Traditional Approaches

The most commonly seen tradtional approaches:
Multi-way switches

Multi-way Switches

Similar to stairwells, multi-way switches can be installed along the length of the hallway. But these require that the wiring be doubled, one for the on circuit and the other for the off circuit. These are not practical as people only tend to turn the lights on but don't bother to turn them off.

Multiple sensors

Multiple Sensor Control

Multiple sensors are installed along the length of the hallway. The problem with this is that installing or replacing the sensors up the ceiling is difficult, and the sensors will switch the lights on and off too frequently, which often results in shortened bulb lifespan. The end result is that breakeven has not yet been achieved before the bulbs need to be replaced.

Main power switch

Main Power Switch

At night, all the lights are turned off from the main power switch, but the next day when the main power switch is turned on, all the lights that were on from the previous night will immediately turn on, there is simply no way to differentiate control for the lights by section.

  • Peak Period: The lighting is forcibly controlled from central control, and all local controls are disabled.
  • Off-Peak Period or Designated Period: Authorize the local controls and allow the local user to take control.

Hallway & Elevator Lobby

Typically used in office buildings, residential building and other types of public buildings.

Busy Periods

All lights during busy periods

All the lights in the hallways and elevator lobbies are turned on.

Slow Periods

Portion of lights are on during slow periods
  • The elevator lobby lights are on to serve as a direction guide.
  • Most of the hallway lights are off, with only a portion remaining on. Sensor control can also be added to the setup.

Short Hallways

Busy Period

Central control takes over the lights during busy periods and will vary depending on whether the hallway is daylit or not.

Short hallways during busy period

Idle Period

Sensors take care of turning on the lights, with a delayed automatic shutoff.

Long Hallways (Switching)

Busy Periods

Central control takes over the lights during busy periods and will depend on whether the hallway is daylit or not.

Centrally controlled during busy period

Slow Periods

The occupant detemines whether or not to turn on the lights, the lights will automatically turn off after a certain delay.

Sensor controlled during slow periods

Long Hallways (Dimming)

Busy Periods

During peak periods, centralized control takes over the lights, and the wall switches are disabled.

Central control turns the lights on (different dimming levels for different time of day) or off (or half dimmed).

Slow Periods

Control reverts to the local wall switches.

The occupant detemines whether or not to turn on the lights, the lights will automatically turn off after a certain delay.

Stairwells

Peak Period

  1. Centralized control determines whether or not to turn on the lights.
  2. During this time the local switches and sensors are disabled.

Off-Peak Period (Solution A)

  1. K15 sensor controls the lights with delayed auto off.
  2. Delay off time is adjustable.

Off-Peak Period (Solution B)

  1. Multiple wall switches are connected in parallel, any switch can turn the lights on or off, with delayed auto off capability.
