NOTES
Models are Listed for indoor use with a temperature range of +32°F to
1.
+120°F (0°C to +49°C) and maximum humidity of 93% RH. The effect of
shipping and storage temperatures shall not adversely affect the perfor-
mance of the appliance when it is stored in the original cartons and is not
subjected to misuse or abuse.
The maximum supervision voltage is 33 volts DC.
2.
Frequency range of speakers is 300-8000Hz.
3.
CAUTION:
Always operate audio amplifiers and speakers within their specified
ratings. Excessive input may distort sound quality and may damage audio equip-
ment. Do not exceed 100% of speaker input voltage per UL 1480. 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.
WIRING AND MOUNTING INFORMATION
CAUTION:
The following figures show the maximum number of field wires (con-
ductors) that can enter the backbox used with each mounting option. If these
limits are exceeded, there may be insufficient space in the backbox to accom-
modate the field wires and stresses from the wires could damage the product.
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-inch (1.9-cm) conduit fittings are used.
Although the limits shown for each mounting option comply with the National
Electrical Code (NEC), Cooper Notification 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.
NOTE
: Surface backbox (SBB) in Figure B is compatible with wiremold and
conduit, mounting holes are for single-gang, double-gang, 4-inch (10.16-cm)
sq. (10.16-cm), 3-1/2-inch (8.9-cm) and 4-inch (10.16-cm) octagon or round
backboxes.
