1. Strip leads 3/8 inches and connect to screw terminals. Multitone Appliances have in-out wiring terminals that accepts two

#12 to #18 American Wire Gauge (AWG) wires at each screw terminal.

2. Break all in-out wire runs on supervised circuits to assure integrity of circuit supervision. The polarity shown in the wiring

diagram is for operation of the appliances. The polarity is reversed by the Fire Alarm Control Panel (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.

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.
