Wheelock AS Series Audible Strobe
Devices & AH Series Audible Devices
Description
Wheelock's patented 2-wire AS Series Audible Strobe Applicances and AH Series Audible Devices offer more features with low current draw. Strobe options for wall mount models include 15/ 75cd or Wheelock's patented MCW multi-candela wall strobes with field selectrable candela settings of 15/30/75/110cd.
Features
* ADA/NFPA/UFC/ANSI Compliant * AS Series Audible Strobe Devices are available in wall and ceiling-mount models: * Wall mount models offered are available with Field Selectrable Candela Settings of 15/30/75/110cd or 15/75cd (single candela model) * Ceiling mount models offered are available with field selectrable candela settings of 15/30/75/95cd * Selectable Continous Horn or Temporal (Code 3) * 3 Selectable dBA settings (99, 95 and 90 dBA) in both tones * Patented 2-Wire Audible Strobe Appliance * Patented Universal Mounting Plate * Weatherproof models are available for outdoor use * Strobes produce 1 flash per second over the regulated voltage range * 12 and 24 VDC models with wide UL "Regulated Voltage Range" using filtered DC or unfiltered FWR input voltage * Synchronize with Wheelock SM, DSM or power supply with builtin Wheelock sync protocol * Fast installation with IN/OUT screw terminals using #12 and #18 AWG wires
AS Audible Strobe
Ceiling mount models incorporate Wheelock's patented MCC multi-candela ceiling strobe with field selectrable intensities of 15/30/75/95cd. The audible provides a selectable choice of either a continous horn or temporal pattern (Code 3) when constant voltage from a Fire Alarm Panel (FACP) is applied. Each tone has 3 dBA settings to choose from.
When used with the Wheelock Series SM or DSM Sync Module or with a power supply with the Wheelock sync protocol, synchronization of the continous horn tone provides the temporal (code 3) tone (mandated by NFPA 72) simultaneously for all audible appliances. This ensurses a distinct temporal (code 3) pattern when 2 or more audibles are AH Audible within hearing distance. If not synchronized the temporal sound could overlap and not be distinctive. At the same time the strobes will be synchronized. This provides the ability to comply with ADA guidelines concerning photosensitive epilepsy and the NFPA standards when installing 2 or more visual appliances within the field of view all of this plus the ability to silence the audible is achieved using only 2 wire.
Listings
Listings and approvals below apply to the basic Wheelock AS Series Audible Strobe Devices and AH Series Audible Devices. In some cases, certain modules may not be listed by certain approval agencies, or listing may be in process. Consult factory for latest listing status. * UL Listed: file E5946. * ULC Listed: file CS356. * MEA approved: file 152-92-E. * CSFM approved: file 71250785:131
General Notes
* Strobes are designed to flash once per second minimum over the Regulated Voltage Range. Note that NFPA-72 (1999) specifies a flash rate of 1 to 2 flashes per second and ADA Guildelines specify a flash rate of 1 to 3 flashes per second. * All candela ratings represent minimum effective Strobe intensity based on UL Standard 1971. * AS Series Strobe products are listed under UL Standard 1971 for indoor use with a temperature range of 32 F to 120 F (O C to 49 C) and maximum humidity of 93% (+ 2%) * AH-24 Series horns are listed under UL Standard 464 for audible signal appliances (indoor use only). * AH-24WP Series audible appliances are listed under UL Standard 464 for indoor/outdoor use with a temperature range of -31 F to 150 F (-35 C to 66 C) and maximum humidity of 95%. * "Regulated Voltage Range" is the newest terminology used by UL to identify the voltage range. Prior this change, UL used the terminology "Listed Voltage Range".

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, 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(R) flashtube enclosed in a rugged LEXAN(R) 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 threeampere 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 VRMS. 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 mm) to #12 AWG (3.25 mm). * 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.
