Not sure if any of you chaps could help me out.
I need to gather some real world info on the view of installers and system designers on central battery v distributed battery emergency lighting systems for stairwells and corridors in flats and care homes etc.
I have heard that some local authorities will not have central battery systems installed in their properties, anyone got any experience of that?
Central battery advantages:
Batteries tend to not need replacing so often.
Central battery disadvantages:
Install cost
Cabling needs to be FP200 to keep lights on in a fire.
Damage to a cable can take out other lights
Volt drop at end of run if 24V is piped about
Distributed battery advantages:
Cheap to install
Distributed battery disadvantages:
Expensive to maintain due to many batteries that don't last that long.
Anyone got anything else to add to those lists? Any system designers out there care to say which they would choose?
Any info greatfully appreciated!
