GENERAL

Wheelock has enhanced the ET Series

high-performance Speakers and Speaker

Strobe combinations. These speakers are

specifically designed to meet the critical

needs of the life safety industry for voice

and tone signaling. These dual voltage (25/

70 volt), multiple tap (from 1/8 to 8 watts)

audio systems now

incorporate a new

low-profile design which results in more

space in standard electrical backboxes.

ET Series Speakers and Speaker Strobes

now incorporate a new speaker mounting

plate for faster and easier installation with

a built-in level adjustment feature, and a

new aesthetically pleasing two-screw grille

cover. Additionally, the ET Series Speaker

Strobe models now incorporate

the

new

low-current,

reduced-inrush,

Wheelock RSS Series Non-Sync/Sync

Strobes (synchronization of the strobe

flash is achieved when used with the

Wheelock SM or DSM Sync Module).

ET Series Speaker Strobes are designed

with maximum performance, reliability and

cost-effectiveness while meeting or ex-

ceeding the latest requirements of NFPA

72 (National Fire Alarm Code), ANSI 117.1

(American National Standard of Accessible

and Usable Buildings and Facilities), and

UL Standard 1971(Standard for Signaling

Devices for the Hearing Impaired). ET

Speaker Strobes, when properly specified

and installed in accordance with NFPA/

ANSI standards, can provide the equiva-

lent facilitation allowed under ADA Acces-

sibility Guidelines (ADAAG General Sec-

tion 2.2) by meeting or exceeding the il-

lumination which results from the ADA

specified strobe intensity of 75 candela at

50 feet (15.24 m). This is an illumination

of 0.030 lumens per square foot.

ET Series Speaker Strobes are UL listed

for indoor use, ceiling- and wall-mounting,

under Standard 1971 for Signaling Devices

for the Hearing Impaired and Standard 1480

for Speaker Appliances. They use a Xenon

flashtube with solid state circuitry enclosed

in a rugged LEXAN® lens to provide

maximum reliability for effective visual

signaling.
