MOUNTING INFORMATION
Figure 1:
CAUTION:
The maximum number of field wires (conductors) that can enter the CBB-8 or other listed equivalent backbox shall comply with the National Electrical
Code (NEC). If this limit is exceeded, there may be insufficient space in the backbox to accommodate the field wires. Stresses from the wires could damage the
product.
Cooper Wheelock also recommends 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.
The S8-70/25, S8-24MCC and S8-24MCCH models are designed to mount flush in a hung tile ceiling. The CBB-8 or other listed equivalent backbox is required per
UL Standard 1480 Speakers for Fire Protective Signaling Systems. When the speaker and backbox cannot be installed directly through a ceiling tile, a support bridge
must be used. Refer to P84239 and P81490 for additional mounting information.

1. The Low Profile Speaker Strobe model has in-out wiring terminals
that accept two #12 to #18 American Wire Gauge (AWG) wires at
each screw terminal. Strip leads 3/8 inches and connect to screw
terminals.
2. Break all in-out wire runs on supervised circuits to assure integrity
of circuit supervision as shown in Figure 3. The polarity shown in
the wiring diagrams is for operation of the appliances.
3. Connect speaker wires to common and positive of terminal block
and select the power tap terminal for 1/8W, 1/4W, 1/2W, 1W, 2W,
4W or 8W; 25V or 70V as required (see Figures 2, 3, 4, 5 and
Table 4).
GROUNDING:
Connect ground wire to backbox. Install signaling appliance to backbox using mounting screws provided.
WARNING: THE SPEAKER STROBE APPLIANCE MUST BE FIELD SET TO THE DESIRED dBA SOUND OUTPUT LEVEL BEFORE IT IS
INSTALLED. THIS IS DONE BY PROPERLY INSERTING JUMPER PLUGS IN ACCORDANCE WITH THESE INSTRUCTIONS. INCORRECT
SETTINGS WILL RESULT IN IMPROPER PERFORMANCE, WHICH COULD RESULT IN PROPERTY DAMAGE AND SERIOUS INJURY OR
DEATH TO YOU AND/OR OTHERS.
