WARNING: FOR UL/ULC APPLICATIONS THESE APPLIANCES WERE TESTED TO THE OPERATING
VOLTAGE LIMITS OF 16-33 VOLTS FOR 24V MODELS OR 96-132V FOR 115V MODELS. DO NOT APPLY 80%
AND 110% OF THESE VOLTAGE VALUES FOR SYSTEM OPERATION.
WARNING: MAKE SURE THAT THE TOTAL RMS CURRENT REQUIRED BY ALL APPLIANCES THAT ARE
CONNECTED TO THE SYSTEM’S PRIMARY AND SECONDARY POWER SOURCES 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 1 to determine the highest value of “RMS Current” for an individual bell (across
the expected operating voltage range of the bell), then multiply these values by the total number of bells; be sure to add the
currents for any other appliances, powered by the same source and include any required safety factors.
