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.

Ceiling mount models incorporate Wheelock’s pat-

ented 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 tem-

poral (code 3) pattern when 2 or more audibles are

within hearing distance. If not synchronized the tem-

poral sound could overlap and not be distinctive. At

the same time the strobes will be synchronized.

This provides the ability to comply with ADA guide-

lines concerning photosensitive epilepsy and the NFPA standards when install-

ing 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.

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”.
