4.7 System Spare Capacity
The UK Fire alarm system code of Practice for Designing, Installing, Commissioning & maintaining fire alarm systems,
BS5839 recommends allowing at least 25% free capacity when designing a fire system.
This is a good precaution as it allows for:-
Changes to the system requirements before the site is finished
Additional devices identified as part of the commissioning process
Future Changes to the building layout (eg partitioning an open plan area)
If a system is designed to full capacity, any small additions might mean substantial changes (network an extra panel, or
change panel to an alternative model)
