6 FITTING THE CONTROLLER INTO ALTERNATIVE CABINETS
The controller rack may be fitted into enclosures other than the single sided
ST950ELV cabinet. In the UK, the controller may only be fitted into an HA-approved
enclosure.
The procedure for fitting an ST950ELV controller into an alternative enclosure is
very dependent on the type of enclosure and the type and position of existing
equipment. For this reason it is not possible to define in detail exactly what needs to
be done.
Detailed installation instructions are included in the drawings contained in
the kit relevant to the cabinet.
When fitting an ST950ELV controller into an enclosure other than an ST950ELV
cabinet, a different type of 6U rack is required (a so-called ‘cuckoo’ rack). This rack
houses up to three LSLS cards and has two 3U high bays which can be fitted with
up to two Intelligent Detector Backplanes, supporting a maximum of eight Loop
Detector cards.
For some cabinets additional kits of parts are available. These provide brackets and
other equipment that may be helpful during the installation. The kits are listed on
667/DZ/46950/000 and contain the necessary installation instructions.
The standard controller items are used with these kits and are listed in the ST950
Family Tree (667/DZ/46950/000). Refer to Siemens Poole for the latest copy.
