Notifier AH Series - Manual (Page 4)

Page 4 of 4 — DN-5566 • 03/30/04
ARCHITECTS’ & ENGINEERS’ SPECIFICATIONS
• The notification appliances shall be Wheelock’s patented AS Series Audible Strobe and AH Series Audible Horn devices, and when
synchronization is required, companion SM and DSM Sync Modules, or approved equivalents. AS Series devices and SM and DSM
Sync Modules shall be listed under UL Standard 1971 (Emergency Devices for the Hearing Impaired for Indoor Fire Protection Service).
AH Series Audible Horn shall be listed under Standard 464 (Fire Protective Signaling). AS, AH, SM, and DSM devices shall be certified
to meet FCC Part 15, Class B.
• The devices shall be designed for two-wire operation and shall provide either a continuous or temporal (Code 3) tone when
constant voltage from a Notification Appliance Circuit (NACs) of the Fire Alarm Control Panel (FACP) is applied; or synchronized
temporal (Code 3) horn and synchronized strobe when used in conjunction with the SM or DSM Sync Modules.
• The AS Series shall be designed so that the audible signal may be silenced while maintaining strobe activation (when used with the
SM or DSM Sync Modules). The SM and DSM Sync Modules shall incorporate two inputs from Notification Appliance Circuits (NACs)
for power connection from the Fire Alarm Control Panel (FACP): one for the strobe circuit (NAC), and one for the audible circuit (NAC).
A single two-wire output shall control both the audible and visual appliances. Upon activation of the audible silence function of the
FACP, the audible signal shall be silenced while maintaining strobe activation.
• Sound output at 10 feet (3.048 m) shall be field-selectable for 90, 95, or 99 dBA anechoic for both continuous or temporal (Code 3)
tone. The AS Series shall provide listed strobe intensities of 15, 15/75, 30, 75, and 110 candela for wall-mount and/or 75 or 100
candela for ceiling-mount applications; with a flash rate of one flash per second minimum across the listed voltage range. The strobe
shall incorporate a Xenon® flashtube enclosed in a rugged LEXAN® lens. The maximum allowable current at 24 VDC shall be 87 mA
@ 15 cd, 102 mA @ 15/75 cd, 120 mA @ 30 cd, 177 mA @ 75 cd, and 202 mA @ 110 cd. All devices shall incorporate a reduced
inrush circuit design. The strobe shall have a horizontal plane.
• The Sync Module shall be designed and available in two versions: the SM-12/24, for control of a single Class “B” NAC circuit; and
a dual-output version, the DSM-12/24, for control of either a single Class “A” or two Class “B” NAC circuits. The DSM dual-circuit
version shall provide the additional capability of “daisy-chaining,” i.e., the ability to interconnect multiple DSM’s for synchronous horn
and strobe operation on multiple NAC circuits. DSM-12/24 interconnection capability shall be for a maximum of 20 modules (40 Class
“B” NAC circuits or 20 Class “A” NAC circuits). Rated average current requirement for the SM-12/24 shall be 0.014 amperes @ 12
VDC and 0.025 amperes @ 24 VDC; the DSM-12/24 shall be 0.020 amperes @ 12 VDC and 0.038 amperes @ 24 VDC. The SM Sync
Module shall be capable of handling a three-ampere load at 12 or 24 VDC. The DSM Sync Modules shall be capable of handling a load
of three amperes per circuit in the Class “B” mode, and three amperes per module in the Class “A” mode at 12 or 24 VDC.
• SM or DSM Sync Modules and AS Audible Strobes shall be designed as a system for continuous activation of the strobes should
the Sync Module contacts fail in the passive state (i.e., contacts remain closed). In this default mode, the strobes shall revert to a non-
synchronized default flash rate.
• AS/AH Series devices shall be designed for operation at 12 or 24 VDC, over their respective listed voltage ranges of 10.5 to 15.6
VDC; and 20.0 to 31.0 VDC. The units shall be designed for operation on filtered DC, or unfiltered V
RMS
. Rated average current for AS
Series devices shall depend upon voltage and strobe intensity; current shall be as low as 0.058 amperes for 24 VDC versions and
0.145 amperes for 12 VDC versions. Rated average current for AH Series devices (volume set at high-dB output) shall be 0.041
amperes for 24 VDC versions and 0.113 amperes for 12 VDC versions.
• All versions shall be polarized for DC supervision and shall incorporate screw terminals for in/out field wiring of size #18 AWG (0.75
mm²) to #12 AWG (3.25 mm²).
• AS/AH shall incorporate a patented Universal Mounting Plate which shall allow mounting to single-gang, double-gang, 4" (10.16 cm)
square, 100 mm European backboxes or Wheelock’s SHBB surface backbox. No additional trim plate shall be required for flush
mounting.
• Dimensions for AS/AH appliances shall be 4.625" (11.7475 cm) square by 1.5" (3.81 cm) deep.
CONTACT WHEELOCK FOR “INSTALLATION INSTRUCTIONS” (Wheelock #P83509 [AS], #P83641
[AH-WP], and #P83519 [AH]) AND “GENERAL INFORMATION” SHEET (Wheelock #P82380) ON THESE
PRODUCTS. THESE MATERIALS UNDERGO PERIODIC CHANGES. IT IS IMPORTANT THAT YOU HAVE CURRENT INFORMATION
ON THESE PRODUCTS. THESE MATERIALS CONTAIN IMPORTANT INFORMATION THAT SHOULD BE READ PRIOR TO SPECIFYING
OR INSTALLING THESE PRODUCTS, INCLUDING:
• TOTAL CURRENT REQUIRED BY ALL DEVICES CONNECTED TO SYSTEM PRIMARY AND SECONDARY POWER
SOURCES.
• FUSE RATINGS ON NAC CIRCUITS TO HANDLE PEAK CURRENTS FROM ALL DEVICES ON THOSE CIRCUITS.
• COMPOSITE FLASH RATE FROM MULTIPLE STROBES WITHIN A PERSON’S FIELD OF VIEW.
• VOLTAGE APPLIED: THE VOLTAGE APPLIED TO THESE PRODUCTS MUST BE WITHIN THEIR RATED INPUT VOLTAGE
RANGE.
• INSTALLATION OF 100/110 CANDELA STROBE PRODUCTS IN SLEEPING AREAS.
• INSTALLATION IN OFFICE AREAS AND OTHER SPECIFICATION AND INSTALLATION ISSUES.
• Note: USE AS/AH ONLY ON CIRCUITS WITH CONTINUOUSLY APPLIED OPERATING VOLTAGE. DO NOT USE AS SERIES
ON CODED OR INTERRUPTED NAC CIRCUITS IN WHICH THE APPLIED VOLTAGE IS CYCLED ON AND OFF, AS THE
STROBE MAY NOT FLASH.
• CONDUCTOR SPECIFICATIONS: CONDUCTOR SIZE (AWG), LENGTH AND AMPACITY SHOULD BE TAKEN INTO
CONSIDERATION PRIOR TO DESIGN AND INSTALLATION OF THESE PRODUCTS, PARTICULARLY IN RETROFIT
INSTALLATIONS.
FAILURE TO COMPLY WITH THE INSTALLATION INSTRUCTIONS OR GENERAL INFORMATION SHEETS COULD RESULT IN
IMPROPER INSTALLATION, APPLICATION, AND/OR OPERATION OF THESE PRODUCTS IN AN EMERGENCY SITUATION, WHICH
