Syncro Focus/Focus+ Repeaters - Network connections
To complement the Syncro and Syncro AS control panels, a range of network repeater panels are available.
The Syncro Response repeater provides a fully functional control and indication repeater panel. From the Syncro Response the user may perform network wide Access level 2 menu operations (including disablements, zone test operations and View devices) as well as Silence, Re-sound and Reset operations.
The Syncro Focus is a basic LCD network repeater which allows specific event types from selected panels on the network to be displayed. This panel has basic controls for “View More Fires”, “View More (other) Events” and “Silence Buzzer”.
The Syncro Focus+ has the same functions as the Syncro Focus, but with the additional Silence, Re-sound and Reset buttons, protected by an Enable Controls key switch.
The Syncro Focus and Focus+ repeaters are unique in their design by the virtue that they are a single board repeater and this circuit board incorporates the network card functionality as well as providing display and control operations.
All other Syncro products use the K555 network card to enable their networking functions. The K555 network card has its own microcontroller, which buffers and passes network events to/from their control panel onto the secure and optically isolated Syncro data network. The K555 network card also has on-board LED indicators to show the Data In / Data Out paths are healthy.
In order to provide a secure and fault tolerant data link between panels, the network is wired in a data loop, with the “Network Out” of one panel wired to the “Network In” of the next.
In the event that a Syncro / Syncro AS or Syncro Response panel has the incorrect network connections (Out to Out or In to In) the network will fail to initialise at all, until the problem is remedied.
However, the integration of the networking hardware onto the Syncro Focus / Focus+ boards has resulted in the characteristic that repeaters will connect and appear to work correctly even if the network connections to the board have been reversed.
The main indication that there may be an incorrect network connection is that the system may report intermittent network error messages and it is not possible to transfer the Syncro Focus / Focus + configuration file to the repeater via the network.
In the event that it is not possible to transfer a configuration file to the Syncro Focus / Focus+ repeater, it is recommended that the network in / out cables are checked to confirm correct connections with the other panels on the network. If it is not possible to transfer a configuration into the Focus and the network cables are correct, then running an Autolearn procedure on the Focus repeater will in most cases allow you to send data into it. To do this follow these steps:
1, Press and hold ‘More Fires & More Events’ together.
2, Momentarily press the CPU micro switch to reboot the unit & keep ‘More Fires & More Events held down for about 30 second and the display should show ‘Autolearn in progress’.
Once this has completed, proceed to upload the configuration into the Focus.
