The signal light SHR-12 SL is a radio-controlled indoor traffic light, which can be used in various applications. The signal light is supplied with power by a plug-in power supply unit. The installation is very easy. Put the plug into the socket and the signal light is ready for use. The light signal has a particularly pleasant light intensity and color and can be clearly recognized even under difficult visibility conditions at a wide angle of 210°. The signal light is compatible with all transmitters of the radio series SH-12. Using a radio module or fixed transmitter, sensor signals can also be used for automated control. The additional function of the ventilation aid can also be used to remind people present that a room is adequately ventilated.

All properties:

  • Easy installation and intuitive operation
  • Pleasant luminous intensity and color
  • 210° viewing angle - easy to see even under difficult lighting conditions
  • Sound signal for color change (adjustable)
  • Control with up to 60 transmitters
  • Additional function: ventilation aid
  • Several signal lights can also be controlled with one transmitter
  • Automated control via sensor signal possible

The signal light for access control

You can easily control who and how many people can enter your rooms, exactly when you want them to. With key 1 or 3 the traffic light is permanently switched to green. Key 2 or 4 switches the traffic light to red. A color change is underlined with a melody that can be switched off.

This way it can be signalled whether a waiting person may enter the room. But also to reduce the number of people in a room the signal light can be used. Typical applications are:

  • Offices
  • Public institutions
  • Meeting rooms
  • Practices
  • Retail

The signal lights as ventilation aid

Ventilate your areas as recommended by experts. Experts recommend a shock ventilation for 3 minutes every hour. Especially in heavily frequented rooms, where several people come together, it is difficult to implement this simple action consistently in everyday life. The cycle is started on the SHR-12 SL with a simple keystroke. The light is green. After 57 minutes a tone signals the change of status and the light changes to red to remind everyone present to perform a shock ventilation. Three minutes later the light changes to green with a tone and the next cycle starts.

In this way, all persons using the system are regularly reminded to ventilate the room sufficiently. Typical areas of application are:

  • Offices
  • Practices
  • Public institutions
  • Meeting rooms
  • Common rooms
  • Production and manufacturing
  • Laboratories and workshops

The signal light SHR-12 SL evaluates every wireless signal from the matching transmitters in the SH-12 wireless series and can switch two red and two green lights. Optionally, potential-free relays can be provided to control external devices.

In order to carry out a command from a transmitter, it must first be taught. Teaching of a transmitter is carried out very easily by means of a button. As required, up to 60 transmitters can be taught with all keys or individual transmission keys. The particular highlight of the SH-12 wireless series is the feedback from the receiver. You can see from the transmitter whether the wireless communication was successful and receive information about the quality of the transmission path. This feedback can also be switched off for special applications.

The assignment of the functions that the transmission keys or transmission commands are intended to actuate is fix.

The receivers in the SH-12 wireless series have extremely low interference because of their special transmission properties. With wireless transmission that is immune to interference and offers extremely short response times, ranges over 1000 m can be achieved. Inside buildings the range is reduced to 20 to 80 m depending on the architectural conditions. For strong, narrow-band interference or use of several parallel wireless systems, the working frequency can be set to meet individual needs. The receivers are given a serial number in the factory. This provides greater security and turns every transmitter into a unique device that can be distinguished easily.

We will be happy to advise you on the selection of appropriate transmitters.


The SHR-12 SL is not compatible to the switching operation of the SHT-12 FS. To use the switching operation of the SHT-12 FS with the SHR-12 SL a factory configuration is necessary. We will be happy to advise you personally on this matter.

A separate transmitter of the SH-12 radio series is required to control the signal lamp.
