THESE MATERIALS CONTAIN IMPOR-
TANT INFORMATION THAT SHOULD BE
READ PRIOR TO SPECIFYING OR IN-
STALLING THESE PRODUCTS, IN-
CLUDING:
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 ULStandard 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 FireAlarm 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. ADAcompliance).
• TOTAL CURRENT REQUIRED BY ALL
APPLIANCES CONNECTED TO SYSTEM
SECONDARY POWER SOURCES.
• FUSE RATINGS ON NOTIFICATION AP-
PLIANCE CIRCUITS TO HANDLE PEAK
CURRENTS FROM ALL APPLIANCES
ON THOSE CIRCUITS.
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.
• COMPOSITE FLASH RATE FROM MUL-
TIPLE STROBES WITHINA PERSON’S
FIELD OF VIEW.
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 (NotificationAppliance Trimplate)
shall be provided.
• ADDING, REPLACING OR CHANGINGAP-
PLIANCES OR CHANGING CANDELA
SETTINGS WILL AFFECT CURRENT
DRAW.
All notification appliances shall be backward compatible.
• RECALCULATE CURRENTDRAWTO IN-
SURE THAT THE TOTAL AVERAGE
