u Sleek modern aesthetics
u Multiple voltages (12 VDC or 24 VDC)
u Voltage test points
The Cooper Wheelock Exceder Series Horns feature a
sleek modern design that incorporates high reliability
to minimize current draw. The reduced current draw
allows for a greater number of devices on the two‑wire
notification appliance circuit. This, in combination with
no tools needed for changing settings, voltage test
points, 12 V or 24 V DC operation, the universal
mounting base, and multiple mounting options results
in a reduced cost of ownership.
These horns provide three sound settings on each
appliance. All the switches to change these settings
can be set without a tool and are located behind the
appliance to prevent tampering.
The separate universal mounting base can be easily
mounted to five industry‑standard back box types.
They can also be pre‑wired to allow full testing of the
circuit wiring before the appliance is installed and the
surface finished. These wall‑mounting horns also
feature voltage test points for taking readings with a
volt meter for troubleshooting or AHJ inspection.

Compatibility
Horn:
These horns provide a selectable Continuous or
Code 3 horn tone when connected directly to the Fire
Alarm Control Panel (FACP). They can also provide a
synchronized Code 3 Horn tone when used in
conjunction with an FACP that incorporates the
Cooper Notification sync protocol, a Cooper
Notification Sync Module, or the Cooper Notification
Power Supply. The Horn Appliances can be field set
for High (HI), Medium (MED), or Low (LO) dBA sound
output.

Mounting Considerations
The Universal Mounting Base supplied with each horn
can be pre-wired. With the supplied Contact Cover in
place, the pre‑wired circuit can be checked for
continuity before the horns are mounted. The horns
snap onto the pre-installed Universal Mounting Bases
with the Contact Covers removed and can be secured
to the base with an optional securing screw. The
Universal Mounting Base flush mounts on single-gang,
double-gang, 4 in. square, 4 in. octal, 3.5 in. octal, and
100 mm European-type back boxes.
Wiring Considerations
The wiring terminals on the Universal Mounting Base
accept two appliance wires with diameters between
12 AWG and 18 AWG (ISO 4 mm2 and 0.75 mm2) at
each terminal.
