Wireless module PULSE TALK

Increased well-being and high energy saving potential via innovative luminaire communication from Waldmann


Villingen-Schwenningen, October 2012: Luminaire manufacturer Waldmann has developed a wireless and so far unique module: PULSE TALK. It reacts to presence detection information, enables luminaires to communicate with each other, and to adjust a pleasant lighting scenario at the office. Additionally, presence information of the luminaires can be transmitted via the EnOcean-compatible wireless module to the building automation. This function holds high energy saving potential for room automation.

PULSE TALK avoids light islands

In modern office environments with presence and daylight-controlled lighting, so-called "light islands" can arise due to changes in the number and location of employees in a room: with the exception of the occupied desks, the whole office remains unlighted. Experience has shown that most employees find such a scenario unpleasant. For that reason Waldmann has developed the retrofittable wireless module PULSE TALK that allows luminaires to communicate with each other and exchange presence information. Several luminaires working together as a group can thus create a light scenario that contributes to a more pleasant work atmosphere.

Luminaires communicate presence changes

When one luminaire in a group detects the presence of a person, it reports this information to the other members of the group. While the transmitting luminaire activates its normal level of work light, the other luminaires in the group switch to a defined background level. The group as a whole thus reacts to the absence or presence of persons by creating a suitable lighting scenario over a broader area. Irritating "light islands" become a thing of the past.

Sophisticated technology and easy setup

The main distinguishing feature of PULSE TALK is its simple operation and installation. Its application doesn’t require any specific preconditions in the building, as is the case with wired systems. The individual luminaires have an automatic teach-in function and can be easily assigned to a group without the help of external software.

Each built-in luminaire module can be assigned to one of 100 possible areas in a building. An area can be a whole floor of a building, for example. Within an area, each luminaire can be assigned to one or two groups out of the 16 available for selection. Groups are, for example, different work areas that may overlap.

One luminaire in the group can take over the function of master, also switching on/off corridor lighting equipped with an EnOcean-compatible wireless actuator. Every assignment can be read or modified directly on the module.

Extended convenience and energy saving possibilities

Presence information detected by the luminaires can be used by the building automation for example to control heating, ventilation or sun-blinds exactly relating to a certain zone. In so doing, high energy savings can be realized. For example, heating is only upregulated if a person is present in the area and otherwise heats only on a lower level.

All luminaires with PULSE TALK can also be switched on/off or dimmed via an external wall transmitter. With it, for example, lighting for cleaning can be activated or deactivated manually; when this is done, the presence and daylight sensing system is inactive. Then, if that special lighting status is not deactivated manually, it switches off automatically after one hour.
