Description
The Wheelock high performance ET Speakers and Speaker Strobes
provide high audio output, clear audibility, dual voltage (25/70 VRMS)
capability and field selectable taps from 1/8 to 8 watts. They are
designed to meet the critical needs of the life safety industry for
effective emergency voice communications, tone signaling and
visible signaling to alert the hearing impaired.
The low profile design incorporates a speaker mounting plate
for faster and easier installation. Each model has a built-in level
adjustment feature and an aesthetic two (2) screw grille cover.
The ET Speaker Strobe models incorporate Low Current draw Series
RSS Strobes.
Strobe options for wall mount models include 1575 cd or Wheelock’s
patented MCW multi-candela strobe with field selectable candela
settings of 15/30/75/110cd or the high intensity MCWH strobe with
field selectable 135/185cd.
Ceiling mount models are available in Wheelock’s patented MCC
multi-candela ceiling strobe with field selectable intensities of
15/30/75/95cd or the high intensity MCCH strobe with field
selectable 115/177cd.
The strobe portion of all ET Strobes may be synchronized when
using the Wheelock DSM Sync Modules, Wheelock Power Supplies
or other manufacturers panels incorporating the Wheelock Patented
Sync Protocol. Wheelock synchronized strobes offer an easy way
to comply with ADA recommendations concerning photosensitive
epilepsy.
ET70 and ET90 Speaker Strobes are UL Listed for indoor use under
Standard 1971 (Signaling Devices for the Hearing Impaired) and
Standard 1480 (Speaker Appliances), and use a Xenon flashtube with
solid state circuitry enclosed in a rugged Lexan® lens to provide
maximum reliability for effective visual signaling. All inputs are
supervised and employ IN/OUT wiring terminals for fast installation
using #12 to #18 AWG wiring.
Color options for Series ET speakers and speaker strobes are red or
white.

General Notes
• Strobes are designed to flash at 1 flash per second minimum over their
“Regulated Voltage Range.” Note that NFPA-72 specifies a flash rate of 1
to 2 flashes per second and ADA Guidelines specify a flash rate of 1 to 3
flashes per second.
• All candela ratings represent minimum effective Strobe intensity based
on UL 1971.
Architects and engineers specifications
The speaker appliances shall be Wheelock ET Speakers and speaker
strobe appliances shall be Wheelock ET Speaker Strobes or approved
equals. The speakers shall be UL Listed under Standard 1480 for
Fire Protective Service and speakers equipped with strobes shall be
listed under UL Standard 1971 for Signaling Devices for the Hearing-Impaired. In addition, the strobes shall be certified to meet the
requirements of FCC Part 15, Class B.
All speakers shall be designed for a field selectable input of either
25 or 70 VRMS, with selectable power taps from 1/8 watt to 8 watts.
All models shall have listed sound output of up to 93 dB at 10 feet
and a listed frequency response of 400 to 4000 Hz. The speaker shall
also incorporate a sealed back construction. All inputs shall employ
terminals that accept #12 to #18 AWG wire sizes.
The strobe portion of the appliance shall produce a flash rate of one
(1) flash per second over the Regulated Voltage Range and shall
incorporate a Xenon flashtube enclosed in a rugged Lexan® lens.
The strobe shall be of low current design. Where, Multi-Candela
Speaker Strobes are specified, the strobe intensity shall have field
selectable settings and shall be rated per UL Standard 1971 at
15/30/75/110cd or 135/185cd for wall mount and 15/30/75/95 cd or
115/177cd for ceiling mount. The selector switch for selecting the.
candela shall be tamper resistant. The 1575 strobe shall be specified
when 15 candela UL Standard 1971 listing with 75 candela on-axis is
required (e.g. ADA compliance).
When synchronization is required, the strobe portion of the appliance
shall be compatible with Wheelock’s DSM Sync Modules, Wheelock
Power Supplies or other manufacturers panels with built-in Wheelock
Patented Sync Protocol. The strobes shall not drift out of synchroniza tion at any time during operation. If the sync module or Power Supply
fails to operate, (i.e., contacts remain closed), the strobe shall revert
to a non-synchronized flash rate.
The speaker and speaker strobe appliances shall be designed for
indoor surface or flush mounting. The speaker and speaker strobe
shall incorporate a speaker mounting plate with a grille cover which
is secured with two screws for a level, aesthetic finish and shall
mount to standard electrical hardware requiring no additional trimplate or adapter.
The finish of the ET speakers and speaker strobes shall be white,
red or nickel plate.
All speakers and speaker strobes shall be backward compatible.
We encourage and support nicet certification 3 year warranty.
