BCS107 Battery Sensor Configuration

Overview

The BCS107 is a battery-powered wireless ceiling sensor providing PIR occupancy/vacancy sensing and daylight harvesting. With up to 5 years of battery life and multiple mounting options, it offers flexible installation without wiring.

BCS107 Features

Feature Description
Power Battery (5-year life)
Sensing PIR occupancy/vacancy
Daylight Harvesting Yes (slower response than wired)
Mounting Multiple ceiling mount options
Wireless Bluetooth mesh connectivity

Physical Controls

Element Function
LED Indicator Flashes when receiving wireless packets
Calibrate/Pairing Button Short press = calibrate, Long press = pair

Pairing the BCS107

Step-by-Step Instructions

  1. Navigate to the Discover page, then tap Switches.
  2. Tap the + button to begin pairing.
  3. Long press the sensor button for 3 seconds.
  4. The LED will flash quickly indicating pairing mode.
  5. Pairing mode lasts 30 seconds.
  6. When the sensor appears in the app, select and add it.

Configuring the BCS107

Basic Configuration

  1. On the Discover page, tap Switches, then tap on the BCS107 sensor.
  2. Tap Settings.
  3. Configure name and association:
  4. Enter descriptive name
  5. Associate to group or individual lights
  6. Tap Save.

Important Note

If you add lights to a group after binding the BCS107, you must return to the BCS107 configuration page and save the settings again.

Calibrating Daylight Harvesting

To Calibrate

  1. Ensure the sensor lens is positioned toward the area to measure ambient light.
  2. Give a short press to the sensor's calibrate button.
  3. The sensor adjusts its baseline reading.

Calibration Tips

  • Calibrate during typical lighting conditions
  • Position lens toward the primary work area
  • Recalibrate if sensor is repositioned

Daylight Harvesting Response

Important

The BCS107's daylight harvesting responds slower than line-powered sensors. This is due to power conservation requirements for battery life.

  • Changes may take longer to take effect
  • Not suitable for spaces requiring instant response
  • Adequate for most general applications

Group Daylight Harvesting

All BCS107 versions support daylight harvesting. When the BCS107 is used for daylight harvesting, it performs daylight harvesting for all lights in the group mapped to the sensor — the entire group dims together from the sensor's single ambient light reading, rather than each fixture adjusting individually.

Required: When using the BCS107 for group daylight harvesting, daylight harvesting must be disabled on every other device in the group — leave only the BCS107 performing it. Multiple daylight-harvesting sensors in one group conflict and cause erratic dimming.

BCS107.C1 hardware switch: The BCS107.C1 has a physical switch to enable daylight harvesting. When this switch is enabled, disable daylight harvesting on all other devices in the group so the BCS107 is the only sensor harvesting daylight for the group.

See Daylight Harvesting Strategies for the group-wide setup path.

Vacancy Mode with Bi-Level Dimming

To provide vacancy sensing with bi-level dimming using the BCS107 with Keilton interior lights:

Setup Steps

Step Action
1 Commission the BCS107 and lights to a zone
2 Create a group and add the lights as members
3 Enable motion sensors on the group, select Vacancy mode
4 Disable daylight harvesting on the group
5 Set appropriate T1, T2, and dim level for the group
6 Dim the group to proper level and save as auto point
7 Bind the BCS107 to this group
8 Calibrate the BCS107

Notes

  • Enable motion on the group even though lights don't have physical sensors
  • This allows the firmware to respond to the BCS107's signals
  • Disabling DLH on the group prevents conflict with the BCS107's DLH

Button Functions Reference

Action Function
Short press Calibrate daylight harvesting sensor
Long press (3 seconds) Enter pairing mode (LED flashes quickly)

Troubleshooting

Issue Cause Solution
Sensor not pairing Not in pairing mode Hold button 3+ seconds
Lights not responding Not bound to group Check group association
DLH slow to respond Normal for battery sensor Expected behavior
Calibration not working Lens position Aim lens toward measurement area
New lights not controlled Settings not re-saved Re-save BCS107 configuration

Battery Life Considerations

  • 5-year expected battery life
  • Slower DLH response conserves power
  • LED flashes indicate activity (normal operation)
