Presentation of the MARANTEC D343,2-433 universal receiver This universal receiver is designed by the MARANTEC brand to ensure the operation of your gate and garage door motors. You will be able to control, using a compatible MARANTEC remote control, all your MARENTEC automations, but also automations from other brands: your motorization will simply need to be able to operate at a frequency of 433Mhz. This receiver is designed by the famous brand MARANTEC, which even today continues to prove its value in the field of electrical systems. Relying on safe materials and unique professionalism, the MARANTEC brand is committed to manufacturing accessories that are as reliable as they are durable. There are two models of the MARANTEC D343.2 universal receiver: the MARANTEC D343.2-433 receiver (frequency: 433Mhz) and the MARANTEC D343.2-868 (frequency: 868Mhz). The MARANTEC D343,2-433 receiver is a 2 channel receiver: each channel will receive codes from different transmitters, which means you can program up to two transmitters to this receiver. If necessary, you can connect a pulse button to each of its channels, which will make it easier to switch the corresponding relay. To connect this pulse button you will need to use the connection cable supplied with the receiver. You can mount the receiver on a wall: it should be as flat as possible. To do this, you need to connect relay channel 1 to contactor NO1-COM1 and relay channel 2 to contactor NO2-COM2. Composition Thanks to high-performance security systems, the MARANTEC D343.2-433 receiver is able to provide you with optimal security. The multi-bit system, which is a unidirectional radio system, will promote and reinforce the safety of your motorization systems. This system analyzes the transmitter signal via a 48-bit coding system. Around 70 million transmission codes will be used by this security system. The multi-bit system allows you to benefit from maximum security for your motorization systems. Thanks to it, your gate and garage door motors will be invulnerable. Some precautions for installation You can use your receiver at low temperatures (up to -20°C maximum) and at higher temperatures (60°C maximum). On the other hand, you should avoid installing your receiver in flood-prone areas, or in unsheltered places where it could come into contact with water (rain, water jets, etc.): indeed , its IP20 protection rating does not provide protection against water. We therefore advise you to carefully choose the location of your receiver, following the installation instructions to the letter. If you are forced to install your receiver outside, you can contact the MARANTEC company and ask them for a protective shell. To install your receiver, simply connect it to your motor using the connection cable supplied with it: its supply voltage is 12/24V, direct or alternating current. This receiver will not be complicated to install, nor too bulky, since it has dimensions of 66 × 62 × 31 mm. For any additional information on installation, encoding, or memory, we invite you to consult the instructions for your receiver, available in PDF or downloadable for free.
