GENERAL:

Wheelock offers a complete line of high performance AC horns. Wheelock's Horns are ideal for General Signaling Applications
where high output, low current draw and dependability are of critical concern.
All models provide rugged, vandal resistant construction with die cast housing to protect the horn mechanism. A full range of
Mounting Options are provided for indoor and outdoor installations.
NOTE: All CAUTIONS and WARNINGS are identified by the symbol
WARNING: PLEASE READ THESE INSTRUCTIONS CAREFULLY.
FOLLOWING INSTRUCTIONS, CAUTIONS AND WARNINGS COULD RESULT IN IMPROPER APPLICATION,

WARNING: FOR UL APPLICATIONS THESE APPLIANCES WERE TESTED TO THE OPERATING VOLTAGE LIMITS
OF 96-132 VOLTS. 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 horn (across
the expected operating voltage range of the horn), then multiply these values by the total number of horns; 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.
