All VFWR voltages are measured with a DC voltmeter. Multiply VFWR voltage by 1.11 to convert
values to VRMS.
Verify electrical ratings specified in Tables 1 and 2 to ensure proper electrical input.
Verify speaker wires are only connected to speaker terminals and strobe wires are only
connected to strobe terminals. Verify wiring at the panel, power supply, and/or NAC
control point is correct.
To calculate the total strobe current:
1.
Use Table 2 to determine the highest value of rated average current for an individual
strobe.
2.
Add this value to the total values of the strobes on the circuit.
3.
Add the current for any other devices powered by the same source, including any
required safety factors.
Note:
Calculate the total audible signal current in the same manner based on the input
voltage and the selected wattage of each individual speaker.
!
CAUTION:
Equipment damage hazard. Improper electrical input may
damage the device or cause it to malfunction.
