NOTE:
The Code 3 Horn and Code 3 Tone (set on HIGH dBA) incorporate the temporal pattern specified by ANSI/NFPA for standard emergency evacuation
signaling. They should be used only for fire evacuation signaling and not for any other purpose.
The Horn and Bell Tones can be used on coded systems with a minimum On-Time of 1/4 second if the audible and strobe are wired to operate independently. All other
tones are recommended for use only on continuous (non-coded)
CAUTION:
Strobes are not designed to be used on coded systems in which the applied voltage is cycled on and off.
WIRING DIAGRAMS:
Figure 3:
1. Multitone Strobe models have 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. The polarity is reversed by the FACP during
supervision.

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.
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.
Although the limits shown for each mounting option comply with the National Electrical Code, 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.
