Guest Brad Posted March 2, 2017 Report Share Posted March 2, 2017 Hi, Is there a 'standard' percentage for loop capacity for addressable fire alarm panel / loops? i.e. Kentec/Apollo 126 unique address numbers available _ 10% left off at installation (for future modifications etc.) = approx. 113 devices to be installed, with 13 'spare' spaces. I hear 10%, 15% & even 20% space 'requirements' for future expansion. Thanks, Brad. Quote Link to comment Share on other sites More sharing options...
AnthonyB Posted March 2, 2017 Report Share Posted March 2, 2017 It's usually down to any recommendations by the manufacturer and the designer. Completely filling a loop is frowned upon by some. At the end of the day a judgement needs to be made as to the potential need for expansion and to what extent when determining if you use a panel with a spare unused loop card, or various percentages of spare space per loop. In a building with an L1 system you may be able to safely load a loop to 95% as there is little scope for alteration (unless it has large open plan areas that could be heavily subdivided in future) where as a building with an L4 system may end up in future having additional detection in future for property protection or change of use.
