WARNING: THE VOLTAGE APPLIED TO THESE PRODUCTS MUST BE WITHIN THEIR RATED INPUT VOLTAGE RANGE.
THE APPLICATION OF IMPROPER VOLTAGE MAY RESULT IN DEGRADED OPERATION OR DAMAGE TO THESE
PRODUCTS, WHICH COULD RESULT IN PROPERTY DAMAGE AND SERIOUS INJURY OR DEATH TO YOU AND/OR
OTHERS.
WARNING: CANDELA SETTING WILL DETERMINE THE CURRENT DRAW OF THE PRODUCT.

* Time duration of Strobe Peak Current is 1 millisecond.
NOTE
: Strobe Inrush Current is less than Rated Peak Current.
WARNING: MAKE SURE THAT THE TOTAL AVERAGE CURRENT AND TOTAL PEAK CURRENT REQ UIRED BY ALL
APPLIANCES THAT ARE CONNECTED TO THE SYSTEM’S PRIMARY AND SECONDARY POWER SOURCES, NAC CIRCUITS,
SM, DSM SYNC MODULES AND THE PS-12/24-8 POWER BOOSTER 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 average or peak currents: Use Table 2 to determine the highest value of “Rated Average Current” for an
individual chime strobe (across the expected operating voltage range of the chime strobe), or the highest value of “Rated Peak Current”
(whichever is higher) of an individual chime strobe (across the expected voltage range of the chime strobe), then multiply the value by
the total number of chime strobes; be sure to add the currents for the chimes and 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’ inrush capacity, the output voltage provided by the power supplies may drop below the
lis ted 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
Chime Strobe is not designed to be used on coded systems in which the applied voltage is cycled on and off.
