Gamewell Cooper-Wheelock NS Series Horn Strobes and 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 portion 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.
Strobe options include 15/75cd or Coo-per-Wheelock’s patented Multi-Candela
strobe with field selectable candela 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 performance, 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 requirements concerning
photosensitive epilepsy. NS Horn Strobe

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”.
Features
- Field Selectable Candela Settings 15/30/75/110cd (24 VDC Multi-Candela models) or 15/75cd in 12 or 24 VDC
- Selectable Continuous Horn or Temporal (Code 3)
- 2 Selectable dBA settings of 90 and 95 dBA in both tones
- 12 and 24 VDC models with UL “Regulated Voltage” using filtered DC or unfiltered VRMS input voltage
- Patented Universal Mounting Plate

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
requirements 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 Trim plate) shall be provided.
All notification appliances shall be backward compatible.
