MOUNTING OPTIONS:
CAUTION: The following figures show the maximum number of field wires (conductors) that can enter the backbox used with
each mounting option. If these limits are exceeded, there may be insufficient space in the backbox to accommodate the field wires
and stresses from the wires could damage the product.
Although the limits shown for each mounting option comply with the National Electrical Code (NEC), Wheelock recommends use of
the largest backbox option shown and the use of approved stranded field wires, whenever possible, to provide additional wiring room
for easy installation and minimum stress on the product from wiring.

WARNING: IF A SUPERVISED SELF-AMPLIFIED SPEAKER APPLIANCE IS OPERATED WITHIN 15 INCHES OF
A PERSON'S EAR, IT CAN PRODUCE A SOUND PRESSURE LEVEL THAT EXCEEDS THE MAXIMUM 120 dBA
PERMITTED BY ADA AND OSHA RULES. EXPOSURE TO SUCH SOUND LEVELS CAN RESULT IN DAMAGE TO A
PERSON'S HEARING.
CAUTION: Check the installation instructions of the manufacturers of other equipment used in the system for any guidelines or
restrictions on wiring and/or locating Notification Appliance Circuits (NAC) and notification appliances. Some system
communication circuits and/or audio circuits, for example, may require special precautions to assure immunity from electrical noise
(e.g. audio crosstalk).
