Tabulating the results for each detector position we get:
Detector
N=1
N=2
N=3
N=4
N=5
N=6
N=7
N=8
N=9
N=10
N=11
N=12
N=13
N=14
N=15
N=16
N=17
N=18
N=19
N=20
N=21
N=22
Power Supply
So 22 detectors just exceeds the power supply guarantee voltage, therefore the answer
for a safe maximum number of detectors is 21.
If this is not a convenient solution then there is scope for increasing the number by
changing the power supply or using thicker (lower resistance) cable.
