SR-SBP2801-BLE Bluetooth Pushbutton Transmitter Module
Important: Read All Instructions Prior to Installation
1. General description
1.1 Basic functionality
SR-SBP2801-BLE enables the realization of energy harvesting wireless switches for lighting, build- ing or
industrial automation control systems using Bluetooth® low energy technology.
SR-SBP2801-BLE is mechanically compatible with existing switch elements enabling quick integration into a
wide range of designs. Key applications are wall-mounted or portable switches either with up to two rockers or
up to four push buttons.
SR-SBP2801-BLE pushbutton transmitters are self-powered (no batteries) and fully maintenance- free. They
can therefore be used in all environments including locations that are difficult to reach or within hermetically
sealed housings. The required energy is generated by an electro-dynamic energy transducer actuated by an
energy bow located on the left and right of the module. This energy bow which can be pushed from outside the
module by an appro- priate pushbutton or switch rocker.
When the energy bow is pushed down or released, electrical energy is created and a radio telegram according
to the Bluetooth® low energy standard is transmitted. This radio telegram transmits the status of all four
contact nipples when the energy bow was pushed down or released. SR-SBP2801-BLE radio telegrams are
protected with AES-128 security based on a device-unique private key.
SR-SBP2801-BLE is available in the following variants:
1.SR-SBP2801-BLE
Stand-alone module without additional components for OEM integration
2.SR-SBP2801K4-BLE
SR-SBP2801-BLE integrated into European-style single / double rocker wall switch housing
3.SR-SBP2801K4-BLE(US)
SR-SBP2801-BLE integrated into US-style single or double rocker pad housing
The term "SR-SBP2801-BLE" as used in this document applies to all product variants unless other- wise
mentioned. Figure 1 below shows from left to right the SR-SBP2801-BLE module, the European wall switches
and the US-style rocker pads.

2. Functional information
2.1 Product overview
The pushbutton transmitter module SR-SBP2801-BLE from Sunricher enables the implementation of wireless
remote controls without batteries. It transmits Bluetooth Low Energy (BLE) data telegrams where the required
energy is provided by a built-in electro-dynamic energy generator.
The SR-SBP2801-BLE product outline with key functional components is shown in Figure 2 below.

2.2 Basic functionality
SR-SBP2801-BLE devices contain an electro-dynamic energy converter which is actuated by an energy bow
(1). This bow is pushed by an appropriate push button, switch rocker or a similar construction mounted onto the
device. An internal spring will release the energy bow as soon as it is not pushed down anymore.
When the energy bow is pushed down, electrical energy is created and a BLE radio telegram is transmitted
which identifies the action (pressed or not pressed) and the status of the four button contacts (2). Releasing
the energy bow similarly generates energy which is used to transmit a different radio telegram.
It is therefore possible to distinguish between radio telegrams sent when the energy bar was pushed and radio
telegrams sent when the energy bar was released.
