Connect speaker wires to common and positive of terminal block and select the power tap terminal for 1/8W, 1/4W, 1/2W, 1W or 2W; 25V or 70V as required (see
Figures 1, 2, 3, 4 and Table 4). Each doubling of rated Watts increases sound output by 3 dBA.
Each letter corresponds to a plug position of the header located on the printed circuit board. Select voltage and wattage as shown in Table 4 below.

NOTE:
The speaker strobe appliances must be set to the desired dBA sound output level before they are installed. This is done by properly inserting jumper plugs in
accordance with these instructions.
WARNING: INCORRECT SETTINGS WILL RESULT IN IMPROPER PERFORMANCE.
CAUTION:
Always operate audio amplifiers and speakers within their specified ratings. Excessive input may distort sound quality and may damage audio
equipment. Improper input voltage can damage speaker. If distortion is heard, check for clipping of the audio appliance with an oscilloscope and reduce the amplifier
input level or gain level to eliminate any clipping.

NOTE:
The E50-24MCWH comes pre-set at 185cd. The E50-24MCW comes pre-set at 15cd.
CAUTION:
The candela select switch must be field set to the required candela intensity before installation. When changing the setting of the candela select
switch make certain that it “clicks” in place. After changing the candela setting the appliance must be retested to verify proper operation. Improper setting of the
candela select switch may result in operation at the wrong candela.
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), Cooper 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.
