The Wheelock® ExcederTM Series of notification appliances feature
a sleek modern design that will please building owners with reduced
total cost of ownership. Installers will benefit from its comprehensive
feature list, including the most candela options in one appliance,
low current draw, no tools needed for setting changes, voltage test
points, 12/24 VDC operation, universal mounting base and multiple
mounting options for both new and retrofit construction.
The Wheelock® ExcederTM Series incorporates high reliability and
high efficiency optics to minimize current draw allowing for a greater
number of appliances on the notification appliance circuit. All strobe
models feature an industry first of 8 candela settings on a single
appliance. Models with an audible feature 3 sound settings (90, 95,
99 dB). All switches to change settings, can be set without the use
of a tool and are located behind the appliance to prevent tampering.
Wall models feature voltage test points to take readings with a
voltage meter for troubleshooting and AHJ inspection.
The Wheelock® ExcederTM Series of wall and ceiling notification
appliances feature a Universal Mounting Base (UMB) designed
to simplify the installation and testing of horns, strobes, and
combination horn strobes. The separate universal mounting
base can be pre-wired to allow full testing of circuit wiring before
the appliance is installed and the surface is finished. It comes
complete with a Contact Cover for protection against dirt, dust, paint
and damage to the contacts. The Contact Cover also acts as a
shunting device to allow pre-wire testing for common wiring issues.
The Contact Cover is polarized to prevent it from being installed
incorrectly and prevents the appliance from being installed while
it is on the UMB. When the Contact Cover is removed the circuit
will show an open until the appliance is installed. The UMB allows
for consistent installation and easy replacement of appliances if
required. Wall models provide an optional locking screw for extra
secure installation, while the ceiling models provide a captivated
screw to prevent the screw from falling during installation.
– Save up to 48% in current draw*
– Up to 9 models now in 1 appliance
– Save up to 14% cost of installation**

General Notes:
General Notes:
• Strobes are designed to flash at 1 flash per second minimum over their “Regulated Voltage Range”.
• All candela ratings represent minimum effective strobe intensity based on UL Standard 1971.
• Series Exceder Strobe products are Listed under UL Standards 1971 and 464 for indoor use with a temperature range of 32°F to 120°F (0°C to 49°C) and
maximum humidity of 93% (± 2%) UL 464 (85% UL 1971).
• Series Exceder horns are under UL Standard 464 for audible signal appliances (Indoor use only).
* UL max current rating is the maximum RMS current within the listed voltage range (16-33 VDC for 24 VDC units). For strobes the
UL max current is usually at the minimum listed voltage (16 VDC for 24 VDC units). For audibles the max current is usually at the
maximum listed voltage (33 VDC for 24 VDC units). For unfiltered ratings, see installation instructions.
Specification & Ordering Information
NOTE: Due to continuous development of our products, specifications and offerings are subject to change without notice in accordance
with Cooper Wheelock Inc., dba Cooper Notification standard terms and conditions.
Architects and Engineers Specifications
The notification appliances shall be Wheelock® Exceder™ Series HS Audible Strobe appliances, Series ST Visual Strobe appliances
and Series HN Audible appliances or approved equals. The Series HS and ST Strobes shall be listed for UL Standard 1971 (Emergency
Devices for the Hearing-Impaired) for Indoor Fire Protection Service. The Series HS and HN Audibles shall be UL Listed under Standard
464 (Fire Protective Signaling). All Series shall meet the requirements of FCC Part 15 Class B. All inputs shall be compatible with
standard reverse polarity supervision of circuit wiring by a Fire Alarm Control Panel (FACP) with the ability to operate from 8 to 33 VDC.
Indoor wall models shall incorporate voltage test points for easy voltage inspection.
The Series HS Audible Strobe and ST Strobe appliances shall produce a flash rate of one (1) flash per second over the Regulated
Voltage Range and shall incorporate a Xenon flashtube enclosed in a rugged Lexan® lens. The Series shall be of low current design.
Where Multi-Candela appliances are specified, the strobe intensity shall have 8 field selectable settings at 15, 15/75, 30, 75, 95, 110,
135, 185 candela for wall mount and 15, 30, 60, 75, 95, 115, 150, 177 candela for ceiling mount. The selector switch for selecting
the candela shall be tamper resistant. The 15/75 candela strobe shall be specified when 15 candela UL Standard 1971 Listing with
75 candela on-axis is required (e.g. ADA compliance). Appliances with candela settings shall show the candela selection in a visible
location at all times when installed.
The audible shall have a minimum of three (3) field selectable settings for dBA levels and shall have a choice of continuous or temporal
(Code 3) audible outputs.
The Series HS Audible Strobe, ST Strobe and Series HN Audible shall incorporate a patented Universal Mounting Base that shall allow
mounting to a single-gang, double-gang, 4-inch square, 3.5-inch octal, 4-inch octal or 100mm European type back boxes. Two wire
appliance wiring shall be capable of directly connecting to the mounting base. Continuity checking of the entire NAC circuit prior to
attaching any notification appliances shall be allowed. Product shall come with Contact Cover to protect contact springs. Removal of
an appliance shall result in a supervision fault condition by the Fire Alarm Control Panel (FACP). The mounting base shall be the same
base among all horn, strobe, horn strobe, wall and ceiling models. All notification appliances shall be backwards compatible.
The Series HS and ST wall models shall have a low profile measuring 5.24” H x 4.58” W x 2.19” D. Series HN wall shall measure 5.24”
H x 4.58” W x 1.6” D. The Series HSC and STC shall been round and have a low profile with a diameter of 6.68” x 2.63” D. Series
HNC ceiling shall have a diameter of 6.68” x 1.50” D.
When synchronization is required, the appliance shall be compatible with Wheelock®’s DSM Sync Modules, Wheelock® Power Supplies
or other manufacturer’s panels with built-in Wheelock® Patented Sync Protocol. The strobes shall not drift out of synchronization at any
time during operation. If the sync protocol fails to operate, the strobe shall revert to a non-synchronized flash-rate and still maintain (1)
flash per second over its Regulated Voltage Range. The appliance shall also be designed so that the audible signal may be silenced
while maintaining strobe activation when used with Wheelock® synchronization protocol.
