Figure 14: Chimes Peak Inrush Current Waveforms
The chimes only have a maximum inrush current as illustrated in
Graphs C and D when both the chime and strobe operate from the same power source
(Figure 14). Otherwise, the chimes have a maximum inrush current as illustrated in
Graphs A and B (Figure 14).
