Bluetooth Microwave Occupancy Sensor Module (BTM-RDR-A) User’s Manual and Design-in Guide 1
Introduction The Douglas Lighting Controls Bluetooth® Microwave Occupancy Sensor Module (BTM-RDR-A) provides automated individual and group control of light fixtures using onboard sensors and Bluetooth technology. The BTM-RDR-A integrates directly in a light fixture and uses a 5.8GHz microwave sensor to detect motion within its field of view to control operation of the fixture. The BTM-RDR-A is powered by the fixture Dim-to-Off enabled LED driver and controls it through a 0-10V interface.

Dimensions The BTM-RDR-A is a single sided PCB module that contains 4 circuit connections on the left side (see Module Pinout diagram below) for 12VDC input and 0-10V dimming control. The 12VDC input pads are referred to as AUX+ and AUX-. The 0-10V dimming pins are referred to as DIM+ and DIM-. Internal to the BTM-RDR-A module the AUX- and DIM- are connected together to the onboard GND. The BTM-RDR-A module also has 4 pads (2 top, 2 bottom) for securing the module to the host PCB.
Installation/Mounting The BTM-RDR-A is designed to be surface-mount soldered to the LED PCB of a lighting fixture and therefore does not require any wiring connections to the fixture. Please refer to the Dimensions section of this document for the size, SMT footprint, and pinout for the module. The module can be handsoldered to the LED PCB or it can be reflow soldered at the same time as the rest of the components on the fixture LED PCB.
Occupancy/Motion-Detection Coverage The BTM-RDR-A module contains a 5.8GHz microwave radar motion sensor capable of detecting motion through non-metallic obstacles making it suitable for applications such as mounting behind a sealed diffusing lens of a light fixture. The charts below represent the approximate detection area of the motion sensor.
Commissioning The BTM-RDR-A module is part of Douglas Lighting Controls Bluetooth lighting control ecosystem and therefore interoperates with other Douglas Bluetooth products such as fixture controllers, other occupancy and daylight sensors, and switches. The BTM-RDR-A also can be integrated with Douglas Lighting Controls Dialog lighting control solution through Douglas Lighting Controls’ BT-GTWY-A Bluetooth-Dialog gateway and a Dialog WLC-4150 Lighting Control Unit (LCU).
FCC and ISED Regulatory Statements FCC Part 15 This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment.
RF Rules The BTM-RDR-A complies with FCC Title 47 Part 15 Subpart C for Intentional Radiators and IC RSS-247 Issue 2. Additional Testing The BTM-RDR-A is only authorized for the specific RF rules specified above. It is the OEM’s responsibility for compliance to any other FCC or IC rules that apply to the host product not covered by the BTM-RDR-A module certification.
