(For full-wave-rectified input voltage, multiply 1.41 by percent value shown in Figure 1.)
WARNING: MAKE SURE THAT THE TOTAL CURRENT REQUIRED BY ALL DEVICES THAT ARE
CONNECTED TO THE SYSTEM'S PRIMARY AND SECONDARY POWER SOURCES AND SIGNALING CIRCUITS
DOES NOT EXCEED THEIR RATED CURRENT. OVERLOADING THESE SOURCES COULD RESULT IN LOSS OF
POWER AND FAILURE TO ALERT OCCUPANTS DURING AN EMERGENCY.
When calculating the total current: use Table 1 to determine the highest value of "Rated Strobe Average Current" for an individual
strobe (across the expected operating voltage range of the strobe); then multiply this value by the total number of strobes; be sure to
add the current for any other devices, including audible signaling devices, powered by the same source and include any required
safety factors. Use Table 2 to calculate the total audible appliance current in the same manner.
WARNING: MAKE SURE THAT ALL FUSES USED ON SIGNALING CIRCUITS ARE RATED TO HANDLE THE
MAXIMUM INRUSH OR PEAK CURRENT FROM ALL DEVICES ON THOSE CIRCUITS. FAILURE TO DO THIS
MAY RESULT IN LOSS OF POWER TO THE SIGNALING CIRCUIT AND THE FAILURE OF ALL DEVICES ON
THAT CIRCUIT TO OPERATE.
When calculating the maximum inrush: use Figure 1 to determine the highest value of "Rated Inrush Current" for an individual strobe
(across the expected operating voltage range of the strobe); then multiply that value by the total number of strobes on the circuit; be
sure to add the inrush currents from any other devices on that circuit and include any required safety factors. The time duration of the
maximum strobe inrush current is shown in Figure 1. Calculate the maximum inrush current for all Multitone audible appliances in
the same manner. The Multitone audible appliances produce a brief inrush current that lasts for just 2 microseconds but can reach a
peak value of 8.0 Amps (11.2 Amps for FWR input).
CAUTION:
Strobes are not designed to be used on coded systems in which the applied voltage is cycled on and off.
