One of the strongest point of DUOX system is the adaptability to any kind of installation. From large buildings compounds to single-family homes, the same system with the same components can provide all the benefits from a Full Digital, Full Duplex system. The key elements to achieve this adaptability are the signal regenerators, elements that can help installers to divide large and complex installation into several basic ones within specifications.
The main purposes of signal regenerators are listed below:
At the end of the day, the signal regenerator should be considered as a fresh new starting point for the signal (just like a panel or a monitor).
In order to adapt to any need installers may have, there are 3 different Signal Regenerators to suit every kind of installation. Their characteristics are listed as follows:
This regenerator has 2 ports: BUS_INPUT and BUS_OUTPUT. It is important to note that it regenerates signal incoming from any port, meaning that it has no directionality.
Figure 1: 1 Way Signal Regenerator Layout
This regenerator does not require programming. The only configuration required is to select a position for the Jumper JP1 that allows to use its integrated line adapter in port BUS_INPUT (Remember that in DUOX, line adaptation is required).
Finally, the signal regenerator includes 3 LEDs to indicate that it is receiving power (POWER LED), that there is data transmission from BUS_INPUT to BUS_OUTPUT (up arrow LED) and that there is data transmission from BUS_OUTPUT to BUS_INPUT (down arrow LED).
This signal regenerator is powered from the bus, so it will require to have a power set (power supply and DUOX filter) close. Also, as the regenerator works as an isolator too, it cuts the DC current transmission, so it requires a power set in each side there are devices connected:

Finally, the signal regenerator requires 1Vpp of signal amplitude to regenerate.
This regenerator is similar to 1 Way Signal Regenerator (Ref. 3256), with the exception that it is programmed with the block number where it is installed, and “filters” communications not belonging to this block, allowing a simultaneous conversation in each interior block. In the picture below, each signal regenerator has been configured with its block number. When there is a call originated in the General Entrance addressed towards Block #01, it will be propagated through the bus, thus reaching BUS_INPUT port of both signal regenerators, but the signal will only pass through the signal regenerator configured with Block Number #01. The signal regenerator with Block Number #00 will prevent the signal from propagating through the section of the installation connected to BUS_OUTPUT. For so, it is important to remark that this device has directionality (there is a difference in the behavior when connecting to BUS_INPUT and BUS_OUTPUT and vice versa).
Figure 3: Conversation filtered by Multichannel Regenerator
To configure Multichannel Regenerator, connect any device already programmed with a Block Number (a panel or a monitor) to BUS_OUTPUT and make a call/use Auto-on within 60s. The regenerator will record internally the Block Number from the call and will filter connections not belonging to that block.
This regenerator’s main purpose is to duplicate the bus, providing 2 similar outputs instead of one. As the previous ones, it regenerates signal coming from any of its ports.
Figure 4: 2 Ways Signal Regenerator
This regenerator is powered by a dedicated Power Supply Ref. 4830, providing power + regenerated signal through B1 and B2. It also can provide power through B, B (same port duplicated) optionally through switch SW1. If SW1 is set to OFF, port B, B won’t provide power (only regenerated signal). Every port of the signal regenerator incorporates a filter, so it is not necessary to include DUOX Filter Ref. 3244 when using 2 Way signal regenerator.
There are LEDS to indicate that there is power and data transmission from/to each port, and a switch to select a value for the line adapter included in port B, B.
Different architectures and different constraint require different solutions. With DUOX you can adapt to very different installation choosing different signal regenerators:

Figure 7: Duplicating risers
Figure 8: Installation with 4 blocks and a General Entrance. Each block can have a conversation simultaneously.
Independently of the complexity of your installation, there is a signal regenerator to fit your needs. Below you can find most common use cases for each one:
As always, do not hesitate to contact After Sales Department from Fermax to ask any question you may have. We hope this information was of use for you.
