Cooper-Wheelock NS Series
Horn Strobes & NH Series Horns
Description
The Cooper-Wheelock Series NS Horn
Strobe Appliances will satisfy virtually
all requirements for indoor, wall mount
applications.
The Series NH Horn and the horn por-
tion of the Series NS include a select-
able continuous horn tone or temporal
pattern (Code 3) with selectable dBA
settings of 90 or 95 dBA.

NS Horn Strobe
Strobe options include 15/75cd or Coo-
per-Wheelock’s patented Multi-Can-
dela strobe with field selectable can-
dela settings of 15/30/75/110cd.
These versatile Horn Strobe Appliances
may be synchronized when used in
conjunction with the Wheelock SM or
DSM Sync Modules or a Power Sup-
ply with the Cooper-Wheelock patented
Sync Protocol. Additionally, the audible
may be silenced while maintaining
strobe activation.

All models of the Series NS and NH
are designed for maximum perfor-
mance, reliability and cost-effective-
ness while meeting or exceeding the
latest requirements of NFPA 72/ANSI
117.1/UFC and UL Standards 1971 and
464 as well as meeting ADA require-
ments concerning photosensitive epi-
lepsy.
Listings
Listings and approvals below apply to
the basic NS Series Strobes and NH
Series Horns. In some cases, certain
modules may not be listed by certain
approval agencies, or listing may be
in process. Consult factory for latest
listing status.
General Notes
• Strobes are designed to flash once per second minimum over their “Regulated
Voltage Range”. Note that NFPA-72 specifies a flash rate of 1 to 2 flashes per
second and ADA Guidelines specify a flash rate of 1 to 3 flashes per second.
• All candela ratings represent minimum effective Strobe intensity based on UL
Standard 1971.
• Series NS Strobe products are listed under UL Standard 1971 for indoor use
with a temperature range of 32°F to 120°F (0°C to 49°C) and maximum humidity
of 93% (± 2%).
• Series NH horns are listed under UL Standard 464 for audible signal appli-
ances (Indoor use only).
•
“Regulated Voltage Range” is the newest terminology used by UL to identify
the voltage range. Prior to this change UL used the terminology “Listed
Voltage Range”.

Engineer’s Specifications
The audible/visual notification appliances shall be Cooper-Wheelock Series NS Horn Strobe
appliances and Series NH Horn appliances or approved equals. The Series NS appliances shall
meet and be listed for UL Standard 1971(Emergency Devices for the Hearing-Impaired for Indoor
Fire Protection Service). The Series NH Horn shall be UL Listed under Standard 464 (Fire
Protective Signaling). The horn strobe shall be listed for indoor use and shall meet the require-
ments of FCC Part 15 Class B. All inputs shall be compatible with standard reverse polarity
supervision of circuit wiring by the Fire Alarm Control Panel (FACP).
The audible portion of the appliance shall have a minimum of two (2) field selectable settings for
dBA levels (90 and 95 dBA) and shall have a choice of continuous or temporal (Code 3) audible
outputs.
The strobe portion of the appliance 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 NS shall be of low current design. Where wall mount, Multi-Candela
appliances are specified, the strobe intensity shall have field selectable settings and shall be
rated per UL Standard 1971 for 15/30/75/110 candela. The selector switch for selecting the
candela setting 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).
When synchronization is required, the appliance shall be compatible with Cooper- Wheelock’s
SM, DSM Sync Modules or a Power Supply with Cooper-Wheelock’s built-in Patented Sync
Protocol. The strobes shall not drift out of synchronization at any time during operation. If the
sync module or Power Supply fails to operate, (i.e., contacts remain closed), the strobes shall
revert to a non-synchronized flash-rate. The appliance shall also be designed so that the
audible signal may be silenced while maintaining strobe activation.
The Series NS Horn Strobes and NH horn shall incorporate a Patented Universal Mounting Plate
that shall allow mounting to a single-gang, double-gang, 4-inch square, 100mm European type
backboxes, or the SHBB Surface Backbox. If required, an NATP (Notification Appliance Trimplate)
shall be provided.
All notification appliances shall be backward compatible.
