Your new hand transmitter must use the same wireless radio system (Multi-Bit or bi·linked) and the same frequency as your opener and your existing hand transmitter. Look on the back of your transmitter or the antenna of your opener to find the frequency.

Marantec uses the following frequencies:

  • 868 MHz
  • 433 MHz
  • 40 MHz (no longer available – please contact your authorised dealer or our customer service if your opener uses this frequency)
  • 27 MHz (no longer available – please contact  your authorised dealer or our customer service if your opener uses this frequency)

Additional frequencies may be available in other countries. To find out more about the frequency, please refer to the question
> Which frequency does my opener use?

If you lose a hand transmitter, it is safer to delete the transmitter from the system or to change the coding of all other transmitters and the opener. This will at least prevent anyone who finds your transmitter from using it. Find out how to delete hand transmitters from the system or change the code by watching the videos that follow. Instructions for doing so vary depending on which wireless radio system is used.

To find out which radio system your hand transmitter uses – Multi-Bit or bi·linked – refer to the question 
> Which wireless system does my opener use?

After carrying out the change, your hand transmitter must be re-programmed. To find out how to do this, refer to the question 
> How can I integrate a Marantec hand transmitter into the opener system?

You can recognise our bi·linked hand transmitter by its long white shape and its two or four buttons or by its square black design. The keys can be locked to prevent the controls from being inadvertently activated while the transmitter is in your trouser pocket or on your key ring etc.

Turning the button lock ON or OFF: 

  • Press the programming button on the back of the hand transmitter with a ballpoint pen for about 5 seconds. This engages or disengages the button lock.
  • Button lock ON: The LED on the front flashes once quickly to show that the button lock has been engaged. 
  • Button lock OFF: The LED on the front flashes twice quickly to show that the button lock has been disengaged.

Using with the button lock ON:

  • You can use the hand transmitter to open or close your door even if the button lock is ON. Just press one of the transmitter buttons for about 2 - 4 seconds.
  • The LED on the front flashes once quickly. This cancels the lock for a 20-second period.
  • You can now use the hand transmitter to open or close your door in the usual way.
  • The LED on the front flashes once quickly and transmits the instruction to move the door.
  • The button lock cancellation is renewed every time that a button is pressed.
  • The button lock engages again if a button is not pressed within the space of 20 seconds.

How can I tell that the button lock is ON?

  • You can tell if you press one of the buttons briefly and you find that the LED on the hand transmitter does not light up and the door does not move.
  • The hand transmitter leaves our factory with the button lock disengaged.

The following models feature a button lock: Digital 564, 572, 633, 663.
To find out how to engage and disengage the button lock and control your door at the same time, watch the following video.

For more customised safety and comfort, Marantec has an extensive range of accessories that we are continually adding to. You can purchase additional hand transmitters with extra features. Or a photocell to secure your door and stop the door from moving as soon as there is an obstruction in its path. There is a battery backup to provide power in an emergency, or a solar panel as an alternative source of energy, and much more besides – look no further than here to find just the right accessories to meet your needs.

Our accessories can be purchased from authorised Marantec retailers.

This new bi·linked accessory operates using a wireless radio system. This saves you the effort of laying cables and means you can place the fingerprint reader anywhere within practical reach. 

To enable you to open your door simply with your fingerprint, all you have to do after purchase is to connect your Digital 528 fingerprint reader to your opener. The fingerprint reader and your fingerprints need to be programmed in order to do so. To find out how to do this, watch the following video.

The Marantec fingerprint reader only works in conjunction with our new bi·linked radio system. Your opener must therefore also operate using the bi·linked system. If this is not the case, this system can normally be fitted at any time to enable you to use our new accessory.

To find out which radio system your opener uses – Multi-Bit or bi·linked – please refer to the question 
> Which wireless radio system does my opener use?

Programming the fingerprint reader Digital 528 with bi·linked

Our new bi·linked accessory operates on a wireless radio system. This saves you the effort of laying cables and means you can place the code keypad anywhere within practical reach. 

To enable you to open your door simply with your 4-digit PIN code, all you have to do after purchase is to connect your Digital 525 or Digital 526 code keypad to your opener. The code keypad and a 4-digit user PIN need to be programmed in order to do so. To find out how to do this, watch the following video.

Marantec code keypads only work in conjunction with our new bi·linked radio system. Your opener must therefore also work with the bi·linked system. If this is not the case, this system can normally be fitted at any time to enable you to use our new accessory.

Programming code keypads Digital 525 and 526 with bi·linked

bi·linked is an extremely secure wireless radio system that Marantec has developed as a completely new system for controlling openers. bi·linked is used in our new hand transmitters such as Digital 663, 564, 572 and 633 as well as in our new radio code keypads and fingerprint reader.

Wireless transmission is extremely secure with an AES standard-compliant 128-bit encoder, as is used for applications such as online banking and encrypted https web pages for ordering processes. A different code is transmitted every time a button is pressed, making it virtually impossible to copy or decrypt the wireless signal.

Openers and accessories using the bi·linked system have the advantage of not only being able to transmit instructions but also receive answers: You can use a hand transmitter, for instance, to find out whether your door is closed. Communication between the opener and control devices is bi-directional and so works in both directions.

Would you like to find out more about the bi·linked system? Please visit for more details.

Multi-Bit is a proven and extremely secure wireless radio system developed by Marantec for controlling openers. Signals sent to openers from hand transmitters, code keypads and other control devices are reliably transmitted with 48-bit encryption.

The use of some 70 million different transmission codes in total ensures an outstanding degree of security. Each opener uses a different code. If one hand transmitter goes missing, for instance, a new code can easily be programmed for all other devices. This means that the lost hand transmitter will no longer work if it falls into the wrong hands.

Multi-bit is a uni-directional radio system which works in one direction only: The hand transmitter sends an instruction and the opener carries it out, for example, by opening the door.

Find out which wireless radio system the opener uses by looking either on the hand transmitter or on the transmitter antenna. A laser marking on the back of the hand transmitter shows the product designation and the frequency. The following list tells you which product uses which radio system:

 

Hand transmitterMulti-Bit      bi·linked
Digital 211, 212, 214, 211, 221, 222, 224, 231, 232          √
Digital 302, 304, 306, 311,  313, 317, 318, 321, 323    √
Digital 564, 572, 633, 663    √

 

If your hand transmitter model is not included in this list, please contact us.

Our hand transmitters are operated in different ways depending on the model range they belong to:
You can tell our bi·linked hand transmitters apart by their long white shape with either two or four buttons or by their square black design. All other designs are our Multi-Bit hand transmitters.  


bi·linked hand transmitters:

  • The LED flashes 10 times: Instead of your hand transmitter reacting to a quick press of a button with a quick flash, the LED on your hand transmitter flashes 10 times? Your hand transmitter is telling you in good time that the battery in the device is almost empty. Please change the battery. 
  • The LED does not light up: Our bi·linked hand transmitters are fitted with a comfortable key lock. The keys can be locked to prevent the controls from being inadvertently activated while the transmitter is in your trouser pocket or on your key ring etc..
    If the LED on the hand transmitter does not light up even though you have pressed a button, the electronic key lock is probably engaged. To find out how to disengage the key lock for a short time or always, please refer to the question: 

    > How do I engage the electronic key lock in hand transmitters with bi·linked?

Multi-Bit hand transmitters:

  • The LED flashes 10 times or lights up weakly just once: Your hand transmitter reacts to a quick press of a button by lighting up weakly for a moment or by flashing 10 times? Your hand transmitter is telling you that the battery in the device is almost empty. Please change the battery. 

To find out how to change the battery, please watch the videos that follow:

If your garage door or garden gate does not open even though you have pressed the hand transmitter, the batteries in your transmitter may be empty. To find out how to tell if this is so and what you need to do in this case, please refer to the question
> I am having problems with my hand transmitter.

If you press the hand transmitter and hear that the opener system is working but the door does not move, the door may be disengaged from the opener system. To find out what to do in this case, please refer to the question
> My garage door or garden gate does not move although I can hear the opener system working.

If you press the hand transmitter and hear the opener system starting up but the door does not move, the door may be disengaged from the opener system. This means that the opener and door are disconnected from each other. In this case, all you have to do is re-engage the opener with the door or gate. There are particular instructions for doing so for different types of opener.

When you re-engage the door or gate with the opener, it is extremely important to ensure that the door or gate is always in the same position as when it was disengaged from the opener! Otherwise, the door or gate may not stop and remain at the preset position, and this may cause the door or opener system to become damaged as a result.

Garage door

  • Go to your opener system and pull the cord with the green ball handle until an audible clicking sound is heard. This means that the engaging mechanism has sprung into action.
  • Move the door by hand until the sliding carriage engages with the rail track again with a second audible clicking sound. Your opener is now re-engaged with the door and the door should now move when the hand transmitter is pressed.

To find out how to re-engage the opener with the door, please watch the video below.

Swing door

  • The engaging or disengaging mechanism is located under the protective flap on the opener head.
  • Open this and activate the interlock either by pressing the red plastic bar downwards or by turning the Allen key provided in a clockwise direction. Your opener is now re-engaged and the door should move when the hand transmitter is pressed.
  • Comfort 560: In our articulated arm opener, the engaging and disengaging mechanism can be accessed from the front of the opener system. Engage the opener again by turning the Allen key provided in a clockwise direction.
  • Comfort 585, 586: The underground opener is engaged directly on the arm. To do so, please re-engage the black plastic lever with the arm. Your opener is now engaged again and the gate should now move when the hand transmitter is pressed.
  • If necessary, you may have to release the engaging and disengaging mechanism beforehand with one of the keys provided if the mechanism is locked.

Sliding gate

  • Comfort 860 (S) / 861 (S) bzw. 850 (S) / 851 (S): The engaging and disengaging mechanism is located inside the opener housing. 
    Please open the front cover of the aluminium housing using one of the keys provided.
    Activate the red interlock on the motor in the interior of the housing using the socket key provided until the gear wheel at the rear re-engages with the toothed rack on the gate.
  • Comfort 880/881: You can easily re-engage the opener system and its plastic cover from the outside using the Allen key provided simply by turning it in a clockwise direction on the front of the opener.


To find a detailed description, please refer to the section entitled "Operation" contained in the installation instructions for the opener. You can also read all installation instructions online in our media centre.

   

Locking mechanism for garage door openers

We have developed additional expansion modules for our Comfort 260, 270, 280 and Comfort 360, 370, 380 garage door openers to provide more light in your garage. These expansion modules are very easy to fit yourself as an upgrade - they are clip-in modules which can simply be plugged in. The result is double the amount of light with only very little additional electricity use thanks to energy-saving LED technology.

All opener settings, such as for your hand transmitters, remain saved, of course, after installation. The LED expansion modules can be purchased from your authorised dealer.

To find out how easy it is to fit the expansion modules, please watch our two videos. Please bear in mind that it is essential to unplug your opener from the socket and so disconnect it from the electricity supply before carrying out any installation work.

It is possible in principle for fit openers on swing and sliding gates with a gradient of up to 10 percent. We recommend that your authorised dealer examines this on a case-by-case basis. We would recommend that you install additional safety devices in your gate system as necessary. These original Marantec accessories can be fitted by your authorised dealer:

For swing gates there is a bracket set for gradients. The Comfort 525, 525 L and Comfort 530 L swing gate openers can be used for gradients of up to 10 percent after seeking and obtaining approval.

For sliding gates, there are radial dampers, also known as rotary dampers, to control the speed. This is important whenever a gradient is present. If the lock on such gates is released, they will automatically start moving without this component. The purpose of a radial damper is therefore to prevent gates from moving too fast. Your authorised dealer will be pleased to advise you about additional safety devices for our gates when they are installed at a gradient.  

No, you can also install the control unit in the garage, in the carport or in some another place. Marantec control units are extremely compact and take up very little space. This gives you great flexibility when installing the control unit. 

Your authorised dealer will advise you on the maximum cable length, the cable cross-section and what you need to bear in mind.

Just a few rules of thumb at this point: Cable extensions of up to 25 metres are not a problem, e.g. to install the control unit in your garage or in the carport. In this case, make sure that the cable has a sufficiently large cross-section (at least 1.5 mm²).

The range of the wireless radio system depends on where the opener and the control device are installed, and can differ depending on their location. To maximise the range, position the opener and control device so that the most direct line as the crow flies runs through masonry or other damping materials as little as possible.

The type and state of the materials which the radio waves pass through plays an important role.  

MaterialRange
Air, open air100 %
Wood, plaster80 to 95 %
Uncoated glass70 to 90 %
Bricks, concrete60 to 90 %
Metallised glass (e.g. insulated glass)      10 to 60 %
Reinforced concrete10 to 50 %
Car bodywork10 to 40 %
Metal walls, metal grille0 to 10 %

 

The higher the percentage and so also the range, the further away you can operate your door. As a general rule, however: For safety reasons, only operate your doors if they are within sight.

To maximise the range of your wireless radio system and be able to operate your doors from as far away as possible, there are certain tips that you should bear in mind when installing your opener system: Avoid unnecessary metal shields such as barriers or housings. Keep as far away as possible from live cables and devices such as lighting or machines. Other potential sources of interference restricting the range include:

  • Mobile phones, baby monitors, switch-mode power supplies
  • Wireless systems such as cordless telephones, wireless audio transmission
  • Computer, audio/video systems
  • Fluorescent lighting
  • Microwave ovens

Keep your distance from these sources of interference or, if possible, avoid having them near your opener at all. The thermal glazing in your car can also affect the range. The least absorption takes place at the level of the A-pillar, i.e. on the left and right side of the windscreen.

The type and state of the materials which the radio waves pass through also plays an important role. To find out which materials only minimally affect the range, please refer to the question
> What range does the wireless radio system have?

If you experience problems with the range, we recommend using an external rod antenna: This considerably improves the range of the hand transmitter and opener.

Our accessories can be purchased from authorised Marantec retailers.

No. There are virtually no harmful emissions from wireless products that could affect the health of people and animals. There are also no harmful effects known to us that our wireless products have on pacemakers or hearing aids.

An important feature that distinguishes our products is that they work with extremely low emissions (less than 10 mW) and that these emissions always occur for a very short time only and are in the millisecond range. In comparision: A mobile telephone works with far higher emissions (up to 1,000 mW) and these occur for a much longer time.

You can therefore rest assured that your Marantec wireless radio system is not harmful, since all Marantec wireless products on the market meet the basic requirements of the European R&TTE directive 1999/5/EC, which has been transposed into the Radio and Telecommunications Terminal Equipment Act (FTEG) in Germany. In addition to complying with all relevant standards relating to radio wave propogation and electrical safety, this also includes compliance with relevant electromagnetic compatibility (EMC) standards and those regulating the safety and protection of persons in electromagnetic fields (EMF).

Yes. Currently all Marantec openers operating with the Multi-Bit wireless radio system are compatible with HomeLink when used with one of the hand transmitters listed below. To find out which wireless radio system your hand transmitter uses – Multi-Bit or bi·linked – please refer to the question
> Which wireless radio system does my opener use?

Yes, you can! Marantec has developed special garage door opener systems that use battery technology and do not require an electrical socket.

For garage doors, the Comfort 260 accu makes you independent of an electricity supply. A high-performance battery provides the opener with power for a long period of time. When the battery needs to be recharged, all you have to do is take it off and plug it into a conventional household electrical socket.

Alternatively, the battery unit can also be connected to a modern solar panel. This enables you to use the power of the sun to create an alternative energy source to the classic electrical socket. The high-capacity panel needs nothing but daylight to provide the opener with power. The energy won is stored by the battery and tapped whenever the door is moved. You can also take the battery unit off and charge it at an electrical socket.

Ein potentialfreier Kontakt dient zur Übertragung eines Zustandes oder von Informationen zwischen elektrischen Geräten. Potentialfrei bedeutet, dass ein Anschluss passiv ist, das heißt selbst keine Spannung liefert bzw. liefern darf. Fremdspannung am potentialfreien Kontakt am Antrieb führt zur Zerstörung seiner gesamten Elektronik.

Öffner- und Schließer-Kontakte schalten den Stromkreis. Das heißt sie stellen eine Verbindung innerhalb eines Stromkreises her oder trennen sie.

Ein Öffner-Kontakt (Ruhekontakt) unterbricht den Stromkreis bei Betätigung. Wenn er ruht und nicht betätigt wird, ist der Kontakt geschlossen.

Ein Schließer-Kontakt (Arbeitskontakt) schließt den Stromkreis bei Betätigung. Wenn er nicht betätigt wird, ist der Kontakt offen. Er muss schließen (arbeiten), damit der Stromkreis geschlossen ist.

Als Einschaltdauer (ED) bezeichnet man den Zeitraum, in dem ein Gerät ununterbrochen genutzt werden darf. Danach hat eine Ruhephase zu erfolgen, um es nicht zu beschädigen oder zu zerstören.

Bei Elektromotoren sind häufig eine Betriebsart und eine Einschaltdauer (ED) in % angegeben. Motoren ohne Angabe oder mit der Betriebsart S1 sind für den Dauerbetrieb geeignet. Geräte mit der Betriebsart S2 sind für den Kurzzeitbetrieb geeignet. Wenn kein Nutzungszeitraum angegeben ist, gilt ein Nutzungszeitraum von 10 Minuten.

Beispiel: Wird ein Garagentorantrieb mit 20 % ED S2 ausgewiesen, dann ist der maximal zulässige Nutzungszeitraum 2 Minuten. Für die Auskühlung werden 8 Minuten benötigt.
