How to Install Motion Sensor Light – Installation Guide

 

A motion sensor is a tool used to detect movement. The device contains an electronic sensor that is triggered by motion, typically used to alert presence of a moving object within a specific field of view. Motion sensors are often used for security applications, businesses, and homes where the users want to be alerted of any movement in a specific area. Motion detectors are typically small in size and detect movement by infrared waves; these waves are typically heat waves that radiate from moving objects such as people, cars, and animals. The movement then electronically triggers lighting fixtures to turn on for a set period of time, depending on your timer.

Access Fixtures’ motion sensors provide automatic switching or dimming when used in combination with 110v dimmable LED drivers. Their compact size makes them suitable for use with most luminaires and these motion sensors feature a built-in daylight sensor and wide detection area up to 52 feet in diameter. The motion sensors used in Access Fixtures luminaires can be detected through glass; plastic; and thin, nonmetal materials. These sensors allow for energy savings and can achieve three-step dimming, making them ideal for use in areas that require a notice of light change before fully switching off.

Additionally, each fixture with a sensor can be run in a seriesoff the same linewith an exterior-based photocell. The photocell automatically adjusts to the day/night cycle by detecting changing light levels, while the motion sensor reacts to any physical movement. Working together, photocells and motion sensors will control your exterior lights to deter intruders by creating the illusion of occupancy.

Installation Guidelines

When installing a motion sensor, there are guidelines to which you and your electrician should adhere:

  • The motion sensor should be installed by a qualified electrician.
  • Ensure power supply is switched off prior to installation or servicing.
  • The sensor should not be modified. This will void any warranty.
  • The sensor should be connected to a stable power supply.

Step-by-Step Guide to Wiring a Motion Sensor:

  1. Turn off the power at the main fuse box.
  2. Using a voltage and circuit tester, test each wire to ensure the power is off.
  3. Attach the motion sensor’s mounting strap to allow you to attach each wire before fully mounting your fixture.
  4. Pair the black supply wire with the black fixture wire.
  5. Pair the white supply wire with the white fixture wire.
  6. Pair the ground supply wire with the ground fixture wire.
  7. Connect each wire using connectors and electrical tape.
  8. If wiring colors do not match, use a voltage meter to identify positive, negative, and ground wires.
  9. Ensure connections are secure.
  10. Attach your fixture to the mounting strip.
  11. Finish installing your fixture by mounting it appropriately.
  12. Turn on the power.
  13. Test your light.

Motion Sensor Wiring Schemes

Motion sensors have a number of detection methods used to provide illuminated coverage of a specific area. There are a number of functions that can be installed on a motion sensor to ensure complete accuracy and avoid false motion detections. For wiring diagrams on these functions, continue reading.

On/Off Function

Motion sensors have the ability to switch on a light when movement is detected and switch off after a set period of time when no motion is detected. To install this feature:

  • Connect your motion sensor to normal control gears (LED drivers or ballasts):

3-Step Dimming Function

Once motion is detected by any of the sensors, a signal will be transmitted to the remaining sensors so all lamps switch on at the same time. When no motion is detected in the area, all lamps will synchronously dim to a low light level after the hold time. To connect to 1–10v dimmable control gears, use the following wiring scheme:

  • To connect to 1–10v dimmable control gears, the wiring as follows:

Daylight Harvesting Controls

Use this feature for lighting systems that should either dim or completely turn off when daylight is available. The daylight sensor level of the motion sensor should be set to disable mode if connected to the daylight sensors:

Daylight Sensor:

The sensor can be set to allow the lamp to illuminate within a defined ambient-light-level threshold. The settings are:

  • I: 2 lux – darkness operation only
  • II: 5 lux – darkness operation only
  • III: 10 lux – twilight operation
  • IV: 25 lux – twilight operation
  • V: 50 lux – twilight operation
  • VI: 100 lux – twilight operation
  • VII: Disable

When set to disable, the daylight sensor will switch on the lamp when motion is detected, regardless of ambient light levels.

Motion Sensor Settings

Each sensor has the ability to customize detection area, hold time, and standby periods by using DIP switches. It is important to note that, when reducing the detection area, the sensitivity of the sensors will also be reduced.

Detection Area

The detection area of your motion sensor can easily be reduced by selecting the appropriate combination on the DIP switches.

Hold Time

A motion sensor’s hold time refers to the period of time the lamp remains 100% illuminated after no motion is detected.

Stand-by Period

A motion sensor’s stand-by period refers to the period of time the lamp remains at a low light before it completely switches off.

Daylight Sensor

A motion sensor can be set to ensure a lamp is only illuminated below a predefined brightness threshold.
