Fitting The Elv Controller Into Alternative Cabinets (Cuckoo) - Siemens ST950 Handbook

When moving parts to an expansion cabinet, just move what is necessary to
accommodate incoming cables. The following order is recommended to minimize work:
1. Loop Detectors
2. I/O Cards
3. LSLS Cards
It is not necessary to have a separate Feeder Pillar for the expansion cabinet.

Fitting the ELV Controller into Alternative Cabinets (Cuckoo)

When fitting an ST950 ELV Controller into an enclosure other than an ST950 cabinet, a
different type of 6U rack can be used, 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.
In the UK, the controller may only be fitted into an HA-approved enclosure.
The procedure for Cuckooing an ST950 ELV Controller into an alternative enclosure is
very dependent on the type of enclosure and the type and position of existing
equipment.
Detailed installation instructions are included in the drawings contained in
the kit relevant to the cabinet.
