BT321

PIR Motion Sensor

A PIR motion input that can trigger assigned Bluetooth lighting groups directly.

BT321 PIR Motion Sensor

What this product improves.

BT321 supports fast local lighting response without waiting for a gateway or cloud round trip. The PIR can broadcast directly to its assigned Bluetooth lighting group, while the gateway manages status, settings and schedules through the wider platform.

Outcome for the property

Respond to movement immediately while keeping building-wide control and scheduling available.

Value for operations

Broadcast directly to the assigned Bluetooth lighting group without a gateway in the critical response path.

How it fits the project

Designed for retrofit lighting and practical motion-triggered workflows in circulation and shared spaces.

Installation approach

Sensor position and group assignment are validated against movement paths, lighting zones and the agreed control sequence.

Best suited to

  • Corridor lighting
  • Lift-lobby lighting
  • Retrofit motion control
  • Local occupancy events

Built for a specific building outcome.

Each capability supports clearer information, faster response, better use of space or simpler operations.

01

Immediate local trigger

Broadcast directly to the assigned Bluetooth lighting group without a gateway in the critical response path.

02

Layered control

Let the gateway manage device status and schedules while local logic continues to respond.

03

Practical energy sequence

Support occupied, standby and long-vacancy lighting states according to the project brief.
