  • Page 12 maximum of 26.4 VDC to a lower voltage, for example 23 VDC. The 3.4 volt drop in the wiring is due to wire resistance. To measure ZAS line voltage drop, use an oscilloscope to measure the peak voltage at the ZAS module and at each analog/addressable device.
  • Page 13 Figure 1 . The Pulses should not be excessively curved, and the turn-on pulse must be present. If some pulses appear excessively rounded and/or the start pulse is missing, too much capacitance is the problem. Referring to Figure 1, the pulse width for all values below 5 Note: VDC must be at least 70% of the pulse width for values above 5 VDC, or the waveform is said to be excessively curved.
