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.

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.

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”.
