SERIES ET SPEAKERS &

Description

Wheelock’s Series ET provides a full range of rugged, high
performance speakers and speaker strobe combinations spe­cifically designed to meet the critical needs of the life safety
industry for voice and tone signaling. A vailable in compact,
aesthetically pleasing package styles, each ET model cov­ers both 25 or 70 volt audio systems. Their high-efficiency
design provides improved evacuation signal, such as the “slow
whoop” and “code-3”. The Series ET provides unequaled per­formance and installation flexibility at the job site, while mini­mizing confusion about mounting and performance capabili­ties.

Series ET S peaker Strobes use an Xenon flashtube with solid
state circuitry enclose din a rugged Lexan® lens to provide
maximum reliability for effective visible signaling.

All Series ET models have IN and OUT wiring terminals that
accept two #12 to #18 American Wire Gauge (A WG) wires at
each terminal. Strobe input s are polarized and audio inputs
include a 10 uF blocking capacitor for compatibility with stan­dard reverse polarity DC supervision of NAC circuits.

Features

• Approvals include: CAN/ULC-S541-99 for speaker appliances
and CAN/ULC-S526-02 for visual appliances

• High efficiency design for maximum output at minimum wattage
across a frequency range of 400 to 4000 HZ

• Field selectable taps for 25 VRMS operation from 1/8 watt to 2
watts

• Field selectable taps for 70 VRMS operation from 1/8 watt to 8
watts.

• Series ET Speaker S trobes models available with 15 candela
strobes featuring low current draw and low temperature com­pensation to reduce power consumption and wiring costs

• All audio and strobe inputs are compatible with standard
reverse polarity type supervisions of circuit wiring by an alarm
panel

• Four attractive package styles for flush, semi-flush or surface
mounting to low cost electrical backboxes

• Choice of vandal resistant die cast grilles (ET -1010/1080) or
general purpose sheet metal grilles (ET-1070/1090)

• Sealed back speaker construction for extra protection and
improved audibility

• Sealed back speaker construction for extra protections and
improved audibility

• Fast installation with IN/OUT screw terminals using #12 to #18
AWG wires

WARNING: PLEASE READ THESE SPECIFICA TIONS AND ASSOCIA TED INST ALLA TION INSTRUCTIONS CAREFULL Y BEFORE USING,

SPECIFYING OR APPL YING THIS PRODUCT. F AILURE TO COMPLY WITH ANY OF THESE INSTRUCTIONS, CAUTIONS OR W ARNINGS
COULD RESULT IN IMPROPER APPLICA TION, INST ALLA TION AND/OR OPERATION OF THESE PRODUCTS IN AN EMERGENCY SITUA TION,
WHICH COULD RESULT IN PROPERTY DAMAGE, AND SERIOUS INJUR Y OR DEA TH TO YOU AND/OR OTHERS.

CAUTION: Always operate audio amplifiers and speakers within their specified ratings. Excessive input may distort sound quality and may
damage audio equipment. Do not exceed +30% of speaker rated voltage per CS 243. Improper input voltage can damage speaker. If distortion
is heard, check for clipping of the audio signal with an oscilloscope and reduce the amplifier level or gain level to eliminate any clipping.

General Notes:

• Strobes are designed to flash at 1 flash per second minimum over their Regulated Voltage Range.

• ET-1010 Speakers are Listed for indoor/outdoor use with a temperature range of -35°C to 66°C (-31°F to 150°F) and maximum
humidity of 95% RH. All other ET Speakers and Speaker Strobes are Listed for indoor use with a temperature range of 0°C to
49°C (32°F to 120°F) and maximum humidity of 85%RH.

WARNING: USE STROBES ONL Y ON NAC CIRCUITES WITH CONTINUOUSL Y APPLIED OPERA TING VOL TAGE. DO NOT USE STROBES ON
CODED OR INTERRUPTED NAC CIRCUITS IN WHICH THE APPLIED VOL T AGE IS CYCLED ON AND OFF , AS THE STROBE MA Y NOT FLASH.

WARNING: AL THOUGH UL TESTING HAS VERIFIED THA T THESE
STROBES FUNCTION EVEN A T 80% OF THEIR MINIMUM RA TING AND
110% OF THEIR MAXIMUM RA TING, WHEELOCK STRONGL Y RECOM­MENDS THAT THE VOL T AGE APPLIED TO THESE PRODUCTS BE
WITHIN THEIR RATED INPUT VOL T AGE RANGE. THE APPLICA TION OF
IMPROPER VOLT AGE MA Y RESUL T IN DEGRADED OPERA TION OR
DAMAGE TO THESE PRODUCTS.

The UL “Listed Rated Input Voltage” uses either filtered (DC) or unfiltered
full-wave-rectified (FWR) voltage. Check the minimum and maximum
output of the power supply and stand by battery and subtract the voltage
drop from the circuit wiring resistance to determine the applied voltage to
the strobes.
