Introduction
The Under Bed Light, UBL4 Motion, consists of a bed light with a sensor that activates when motion isdetected. It is intended for use within primarily nursing homes and homecare and works with LINAK®
analogue and OpenBus™ systems.
The guiding light automatically turns on when the patient leaves the bed and therefore helps prevent fall
accidents in poorly lit rooms. The automatic light eases patient orientation and offers more comfort.
The UBL4 Motion offers the following advantages:• Integrated Passive Infra-Red (PIR) sensor for automatic LED light by motion detection• The UBL4 Motion is intelligent and will only activate when light is needed, i.e. in poorly lit rooms• LED light dims after 10 seconds of inactivity.
• IPX4• Easy installation on new and existing systems• Works on both analogue and OpenBus systems

Functionality
The UBL4 Motion is equipped with an integrated PIR sensor for automatic light by motion detection. TheUBL4 Motion also has a photodiode for daylight detection. The UBL4 Motion only turns on when the roomis dark (room lux level below 35).
The functionality is the same on analogue and OpenBus systems.

Functionality visualisation
1. Patient is in bed

2. Patient is sitting up, thus activating the bed sensor

3. Patient walks away from the bed and exits the motion detection zone. After 10 seconds ofinactivity, the guiding light dims.

5

UBL4 |
4. Patient returns to the bed, activates the bed sensor and guiding light is back on max intensity.
When the patient enters the bed again, the guiding light will dim after 10 seconds and turn off after
10 minutes.

5. The sensor field of vision is obstructed, in this case by the bed sheets, and will not function.

6. The guiding light will only turn on in poorly lit rooms. (Guiding light will turn on when night thresholdis below approximately 35 lux. The guiding light will not turn on when light is above approximately
75 lux.
