WARNING: CHECK THE MINIMUM AND MAXIMUM OUTPUT OF THE POWER SUPPLY AND STANDBY
BATTERY AND SUBTRACT THE VOLTAGE DROP FROM THE CIRCUIT WIRING RESISTANCE TO DETERMINE
THE APPLIED VOLTAGE TO THE STROBES.
WARNING: CANDELA SETTING WILL DETERMINE THE CURRENT DRAW OF THE PRODUCT.

WARNING:
MAKE SURE THAT THE TOTAL RMS CURRENT REQUIRED BY ALL APPLIANCES THAT ARE
CONNECTED TO THE SYSTEM'S PRIMARY AND SECONDARY POWER SOURCES, NAC CIRCUITS, SM, DSM SYNC
MODULES OR WHEELOCKS POWER SUPPLIES DO NOT EXCEED THE POWER SOURCES' RATED CAPACITY OR THE
CURRENT RATINGS OF ANY FUSES ON THE CIRCUITS TO WHICH THESE APPLIANCES ARE WIRED. OVERLOADING
POWER SOURCES OR EXCEEDING FUSE RATINGS COULD RESULT IN LOSS OF POWER AND FAILURE TO ALERT
OCCUPANTS DURING AN EMERGENCY, WHICH COULD RESULT IN PROPERTY DAMAGE AND SERIOUS INJURY OR
DEATH TO YOU AND/OR OTHERS.
When calculating the total currents: Use Table 2 to determine the highest value of "RMS Current" for an individual strobe (across the
expected operating voltage range of the strobe), then multiply these values by the total number of strobes; be sure to add the currents
for any other appliances, including audible signaling appliances, powered by the same source and include any required safety factors.
If the peak current exceeds the power supplies' peak capacity, the output voltage provided by the power supplies may drop below the
listed voltage range of the appliances connected to the supply and the voltage may not recover in some types of power supplies. For
example, an auxiliary power supply that lacks filtering at its output stage (either via lack of capacitance and/or lack of battery backup
across the output) may exhibit this characteristic.
CAUTION: The Speaker Strobe is not designed to be used on coded systems in which the applied voltage is cycled on and off.
