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.

MOUNTING NOTES:
CAUTION
: Check that the installed product will have sufficient clearance and wiring room prior to installing backboxes and
conduit, especially if sheathed multiconductor cable or 3/4" conduit fittings are used.
1) Mounting hardware for each mounting option is supplied.
2) When terminating field wires, do not use more lead length than required. Excess lead length could result in insufficient wiring
space for the signaling appliance.
3) Use care and proper techniques to position the field wires in the backbox so that they use minimum space and produce minimum
stress on the product. This is especially important for stiff, heavy gauge wires and wires with thick insulation or sheathing.
4) Do not pass additional wires (used for other than the signaling appliance) through the backbox. Such additional wires could result
in insufficient wiring space for the signaling appliance.
5) Place ‘Beauty Plugs’ over screw heads after installation using the mounting hardware supplied.
6) For Fire Alarm applications using white MIZ-Mini Horns, a red "Fire" Label is provided. Affix this label to the front of the
mounting plate to identify the function of the alarm appliance.

FOR SUCH USE.
If this appliance is required to produce a distinctive three-pulse Temporal Pattern Fire Alarm Evacuation Signal (for total evacuation)
in accordance with NFPA 72, 1999 Edition, the appliance must be used with a Fire Alarm Control unit that can generate the temporal
pattern signal. Refer to manufacturer’s installation manual for details.
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 electrical noise immunity (e.g.
audio crosstalk).
