NOTIFIER Wheelock HS4-HS Series Single and Multi-Candela
GENERAL
The Wheelock Series HS4 Horn Strobe and HS Horn Appliances are an ideal choice
for retrofit applications as well as new installations. They satisfy virtually
all requirements for indoor, wall mount applications.
The Series HS Horn and the horn portion of the Series HS4 include a selectable
continuous horn tone or temporal pattern (Code 3) with three selectable dBA
settings for each tone.
Strobe options include 1575cd or Wheelock’s patented MCW Multi-Candela strobe
with field selectable candela settings of 15/30/75/110cd or the high intensity
MCWH strobe with field selectable 135/185cd.
The Series HS4 horn and strobe inputs are electrically isolated to allow for
independent operation of the strobe circuit and the horn circuit. The horn and
strobe may also be wired in parallel to operate on a single circuit.
These versatile Horn and Horn Strobe Appliances may be synchronized when used
in conjunction with the Wheelock SM or DSM Sync Modules or with a power supply
with the patented Wheelock Sync Protocol.
All models are designed for maximum performance, reliability and cost-
effectiveness 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.
FEATURES
- Field Selectable Candela Settings: 15/30/75/110cd or 135/185cd (Multi-Candela models) or 1575cd (single candela model)
- Selectable Continuous Horn or Temporal (Code 3)
- 3 Selectable dBA settings of 90/95/99 dBA in both tones
- 4-Wire Horn Strobe Appliance allows for separate operation of the horn and strobe circuits
- ADA/NFPA/UFC/ANSI compliant
- Complies with OSHA 29, Part 1910.165
- 24 VDC models with 16 to 33 VDC UL “Regulated Voltage” using filtered DC or unfiltered VRMS input voltage
- Wall mount flush to standard 4-inch square or double-gang boxes or surface mount to IOB backbox
- Synchronize with Wheelock SM, DSM Sync Module or a Power Supply with the built-in Wheelock sync protocol
- Fast installation with IN/OUT screw terminals using #12 to #18 AWG wires

GENERAL NOTES
- Strobes are designed to flash at 1 flash 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 HS4 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 HS horns are listed under UL Standard 464 for audible signal appliances (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”.
NOTE: All CAUTIONS and WARNINGS are identified by the symbol
All warnings are printed in bold capital letters.

ARCHITECTS AND ENGINEERS SPECIFICATIONS
The audible/visual notification appliance shall be Wheelock Series HS4 Horn
Strobe and HS Horn Appliances or approved equals. The Series HS4 and HS
appliance shall meet ad be listed for UL Standard 1971 (Emergency Devices for
the Hearing-Impaired for Indoor Fire Protection Service) and Standard 464
(Fire Protective Signaling). The horn strobe shall be listed for indoor use
and shall meet the requirement 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 HS Horn and the audible portion of the HS4 appliance shall have a minimum
of three (3) field selectable setting for dBA levels 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 HS4 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: 15/30/75/110cd or 135/185cd. The selector switch for
selecting the candela setting shall be tamper resistant. The 1575 candela
strobe shall be specified when 15 candela UL Standard 1971 Listing with 75
candela on-axis is required.
When synchronization is required, the appliance shall be compatible with
Wheelock’s SM, DSM Sync Modules or Wheelock’s PS-12/24-8MP Power Supply with
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.
All notification appliances shall be backward compatible.
