FEATURES
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.
