Specifications
The audible/visual notification appliances shall be Wheelock
Series NS Horn Strobe appliances and Series NH Horn appli-
ances 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 05 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 never 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 1575 candela strobe shall be specified
when 15 candela UL Standard1971 Listing with 75 candela
on-axis is required (e.g. ADA compliance).
When synchronization is required, the appliance shall be com-
patible with Wheelock’s SM, DSM Sync Modules or a Power
Supply with 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, and 100 mm Euro-
pean backboxes, or the SHBB Surface Backbox. If required,
an NATP (Notification Appliance Trimplate) shall be provided.
All notification appliances shall be backward compatible.
