u Sleek modern aesthetics

u Multiple voltages (12 VDC or 24 VDC)

u Voltage test points

The Cooper Wheelock Exceder Series Strobes feature
a sleek modern design that incorporates high reliability
and high-efficiency optics 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 eight candela options
in one appliance, 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 strobes provide eight candela settings. 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 strobes also
feature voltage test points for taking readings with a
volt meter for troubleshooting or AHJ inspection.

Installation/configuration notes

Compatibility

Strobe:
These strobes provide a non-synchronized strobe
appliance when connected directly to a Fire Alarm
Control Panel (FACP), or provide a synchronized
strobe appliance 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. They are designed
to flash at 1 flash per second minimum over their
Regulated Voltage Range.

Mounting Considerations

The Universal Mounting Base supplied with each
strobe can be pre-wired. With the supplied Contact
Cover in place, the pre‑wired circuit can be checked
for continuity before the strobes are mounted. The
strobes 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 single­gang, 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.
