INC.
SERIES ET
LOW PROFILE
SPEAKER STROBES
Description
ET high performance speaker strobe combinations 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)
speakers incorporate a low profile design which results in
more space in electrical backboxes.
The Series ET Speaker Strobes incorporate a speaker
mounting plate for faster and easier installation with a built-
in level adjustment feature along with an aesthetic two (2)
screw grill cover. Additionally, the Series ET Speaker Strobe
models incorporate the Low Current, Zero Inrush, Series
RSS Non-Sync/Sync Strobes (synchronization of the strobe
flash is achieved when used with SM or DSM Sync Module
or FF8 Power Supply) .
Series ET Speaker Strobes are designed with maximum
performance, reliability and cost-effectiveness while meeting
or exceeding 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 Equivalent Facilitation allowed
under ADA Accessibility Guidelines (ADAAG General Section
2.2) by meeting or exceeding the illumination which results
from the ADA specified strobe intensity of 75 candela at 50
feet. This is an illumination of 0.030 lumens per square
foot. Series ET Speaker Strobes are UL Listed for indoor
use, ceiling and wall mount, under Standard 1971 for
Signaling Devices for the Hearing Impaired and Standard
1480 for Speaker Appliances, and use a Xenon flashtube
with solid state circuitry enclosed in a rugged Lexan lens to
provide maximum reliability for effective improved audibility.
The Series ET weatherproof model can be used not only in
outdoor applications but also in damp indoor locations as
well such as clean room and food storage facilities. The
Series ET weatherproof model incorporates an
environmentally adaptive strobe. Candela output vary from
88.3CD to 212CD over a temperature range of 31
o
F to 150
o
F.
