Engineer’s Specifications

• The notification appliances shall be Wheelock’s patented AS Series Audible Strobe

and AH Series Audible Horn devices, and when synchronization is required, compan-

ion 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 Ap-

pliance Circuit (NACs) of the Fire Alarm Control Panel (FACP) is applied; or synchro-

nized 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 main-

taining 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 aver-

age 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 ver-

sions. 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 ter-

minals 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.

Wheelock products must be used within their published specifications and must be PROPERLY

specified, applied, installed, operated, maintained, and operationally tested in accordance with

their installation instructions at the time of installation and at least twice a year or more often and

in accordance with local, state, and federal codes, regulations, and laws. Specification, appli-

cation, installation, operation, maintenance, and testing must be performed by qualified person-

nel for proper operation in accordance with all of the latest National Fire Protection Association

(NFPA), Underwriters’ Laboratories (UL), National Electrical Code (NEC), Occupational Safety

and Health Administration (OSHA), local, state, county, province, district, federal, and other

applicable building and fire standards, guidelines, regulations, laws, and codes including, but

not limited to, all appendices and amendments and the requirements of the local authority having

jurisdiction (AHJ).
