Plug and Play

The modular construction system allows you to upgrade your SOMMER base+ with a versatile collection of accessories. All accessories can be easily installed in the appropriate sockets, which are colored and labled.


Magnetic locking, that locks the engine in every position for attacking forces of up to 300 kg. The lock is blocking mechanically and improves the existing burglary protection.


For measuring temperature and humidity of the garage. The carriage will automatically open the door as much as it is needed and provides perfect air circulation. Once the ideal value is reached, the door will be closed again and the risk of molding decreases.


The Memo provides additional memory extension for up to 450 radio commands. If needed, saved data can be transferred to a new carriage.


Additional LED-lighting for the ceiling control. The additional lighting will be connected in parallel to the lighting of the carriage and can be switched on and off via radio control.


The buzzer offers two options alternatively in one product: If the sound sensor, which is integrated in the motor carriage, detects a burglary attempt the alarm buzzer plays a loud warning sound. The warn buzzer however makes a sound while closing. 


The park position laser gives you an optical assistance to park your vehicle in the garage perfectly. The laser is active while the door is opening and stays active as long as defined in the duration settings.


Additional relay for additional switching of a garage or courtyard light.


Uses a passive infrared sensor to detect the invisible thermal radiation of moving bodies (humans/animals, etc.) and reacts to them. The operator lighting (additional lighting/relay) switches on automatically for safe movement when the garage is entered.


Assumes the power supply of the operator for > 5 door cycles in the event of a power failure.


Output OC

Allows the connection of two corded pulse buttons for control of the door and one external lighting unit. The operating mode “Defined opening” and “Defined closing” is optional.



Transfers the door status (open/closed) to Smart Home systems. Optionally, a further external lighting unit can be operated.



For easier and more convenient installation of the tension springs on sectional doors. It is no longer necessary to lift the door yourself, making installation of the door even easier and quicker.

The LIFTer is only available for specialist dealers.
