The number of devices that can be fitted to a zone when using schottky diode bases. The figure stated ensures that all detector fires/
faults are registered under various worst case scenarios e.g. Fire detection with devices removed from bases:- all but the last device
removed from it’s base; 32 Ohms cable impedance; no E.O.L device fitted (open circuit).
Also note that calculations assume an Active end of line device exhibiting a ‘fault current’ of no more than 40uA.
