To date, the Syncro firmware supported both Hochiki AND Apollo protocol panels and would decide the protocol of the panel at start-up, by interrogating the protocol specific loop cards. The advantage of this technique is that a single display card could be manufactured for both Hochiki and Apollo protocol panels. However, providing this facility means that quite a lot of storage space is used in the program, to support the unused protocol. As the Syncro product has evolved and new features have been added, the program has expanded in size. As a result of previous amendments the program had reached the maximum size possible for the Syncro display hardware memory and therefore no additional features could be added. In order to allow additional devices and features to be implemented, it has become necessary to split the protocols. This means that there will be a Hochiki only firmware and an Apollo only firmware and the fact that these are now single protocol firmware versions means that the memory size required has been reduced.        Splitting the Syncro protocol firmware has provided some additional memory, which can be used for additional device support and new features. How does split protocol affect me? The Syncro S550EN display card previously used for Apollo and Hochiki control panels will no longer be available. In place of this display card there will be two new items; S550ENA Apollo Protocol Syncro EN54 approved display card This display card hardware is identical to the current S550EN but the firmware loaded will be ONLY for Apollo protocol EN54 Kitemarked panels. S550ENH Hochiki Protocol Syncro EN54 approved display card This display card hardware is identical to the current S550EN but the firmware loaded will be ONLY for Hochiki protocol EN54 Kitemarked panels. It is essential that the display card protocol match the loop card protocol within the control panel. If the protocol does not match, then an "incorrect protocol" fault will be given. When ordering warranty replacement parts, or spare parts, it is essential that the correct protocol of the control panel be specified. Syncro Response repeater control panels can be fitted with either protocol part, because both firmware versions will recognize that when no loops are detected, the panel is repeater. What about networked systems? All Syncro panels on a network should be installed with the same firmware version, to ensure compatibility and correct support of the features provided. If the Syncro network comprises of both BSI Kitemarked panels and the older non-EN panels, then it will be necessary to update all panels. To allow the older panels to be updated we have a different firmware version. This firmware version is generically referred to as "EN compatible" and has identical functionality to the approved firmware, but does not monitor the display card "write enable" switch position. The EN compatible firmware MUST only be installed on display cards that do not have the write enable switch fitted (up to issue 10 K6001 circuit boards). NOTE: Very old display cards fitted with the AMD microprocessor may occasionally cause intermittent watchdog faults when updated. Consideration should be given before updating any S550 display card firmware if the AMD microprocessor is fitted. What firmware goes where? For the Syncro control panel, there are four different firmware files. Panel protocolPanel hardwareFile to useApollo protocolEN-54 approved panels (BSI Kitemark, display card issue 11 or later with write enable switch)SV570UK_Apollo.binNon-approved panels (display card issue 10 or earlier, no write enable switch)SV570UK_Apollo_EN54Compatible.binHochiki protocolEN-54 approved panels (BSI Kitemark, display card issue 11 or later with write enable switch)SV570UK_Hochiki.binNon-approved panels (display card issue 10 or earlier, no write enable switch)SV570UK_Hochiki_ENCompatible.bin The Syncro AS panel has a single file for both protocols. This is possible because the Syncro AS panel has additional memory to store the dual protocol firmware. The compatible file for the Syncro AS is SV520AS_UK.bin What about the older control panels? Non-EN approved control panels in standalone applications are currently fitted with firmware version up to V4.XX. These control panels have a slightly different mode of operation to the BSI approved control panels with firmware versions V5.XX onwards. However the same memory size restriction also applies to these panels and therefore we are unable to provide additional features to these control panels, including support the new devices. No further development or enhancements will be undertaken on these control panels and the current release version of the firmware will not be updated. If it is required to support new devices on these control panels, then the mode of operation will need to be revised to the EN54 mode and the panels loaded with the appropriate EN54 compatible firmware for the appropriate protocol.
