Notifier ET Series - Manual (Page 2)

Page 2 of 4 — dn-2225:a1 • 2/9/10
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 inten-
sity based on UL Standard 1971.
• Series ET Speaker Strobes and Series ET Speakers are
listed under UL Standard 1971 for indoor use with a tempera-
ture range of 32°F to 120°F (0°C to 49°C) and maximum
humidity of 85%.
• Wheelock Weatherproof Appliances are designed to operate
over an extended temperature of -40° F to 150°F (-40°C to
66°C) and all candela ratings represent minimum effective
strobe intensity based on UL 1638. Maximum humidity of
93% RH + 2%.
• “Regulated Voltage Range” is the newest terminology used
by UL to identify the voltage range. Prior to this change UL
used the terminology “Listed Voltage Range”.
ARCHITECTURAL/ENGINEERING
SPECIFICATIONS
The speaker appliances shall be Wheelock Series ET Speakers
and speaker strobe appliances shall be Wheelock Series 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 Stan-
dard 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 inten-
sity 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 com-
pliance).
When synchronization is required, the strobe portion of the
appliance shall be compatible with Wheelock’s SM, DSM sync
modules or a a power supply with built-in Wheelock Patented
Sync Protocol. The strobes shall not drift out of synchronization
at any time during operation. If the sync module or Power Sup-
ply 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 fin-
ish and shall mount to standard electrical hardware requiring no
additional trimplate or adapter. The finish of the Series ET
speakers and speaker strobes shall be white, red or nickel plate.
All speakers and speaker strobes shall be backward compatible.

“GENERAL INFORMATION” SHEET (P82380) ON THESE PRODUCTS. THESE DOCUMENTS UNDERGO
PERIODIC CHANGES. IT IS IMPORTANT THAT YOU HAVE CURRENT INFORMATION ON THE PRODUCTS.
THESE MATERIALS CONTAIN IMPORTANT INFORMATION THAT SHOULD BE READ PRIOR TO
SPECIFYING OR INSTALLING THESE PRODUCTS, INCLUDING:
• TOTAL CURRENT REQUIRED BY ALL APPLIANCES CONNECTED TO SYSTEM SECONDARY
POWER SOURCES.
• FUSE RATINGS ON NOTIFICATION APPLIANCE CIRCUITS TO HANDLE PEAK CURRENTS FROM
ALL APPLIANCES ON THOSE CIRCUITS.
• COMPOSITE FLASH RATE FROM MULTIPLE STROBES WITHIN A PERSON’S FIELD OF VIEW.
• ADDING, REPLACING OR CHANGING APPLIANCES OR CHANGING CANDELLA SETTINGS WILL
AFFECT CURRENT DRAW. RECALCULATE CURRENT DRAW TO INSURE THAT THE TOTAL
AVERAGE CURRENT AND TOTAL PEAK REQUIRED BY ALL APPLIANCES DO NOT EXCEED THE
RATED CAPACITY OF THE POWER SOURCES OR FUSES.
• THE VOLTAGE APPLIED TO THE PRODUCTS MUST BE WITHIN THEIR “REGULATED VOLTAGE
RANGE.”
• INSTALLATION OF 110 CANDELA STROBE PRODUCTS IN SLEEPING AREAS.
• INSTALLATION IN OFFICE AREAS AND OTHER SPECIFICATION AND INSTALLATION ISSUES.
• THESE APPLIANCES ARE NOT DESIGNED TO BE USED ON CODED SYSTEMS IN WHICH THE
APPLIED VOLTAGE IS CYCLED ON AND OFF.
• FAILURE TO COMPLY WITH THE INSTALLATION INSTRUCTIONS OR GENERAL INFORMATION
SHEETS COULD RESULT IN IMPROPER INSTALLATION, APPLICATION, AND/OR PROPERTY
DAMAGE AND SERIOUS INJURY OR DEATH TO YOU AND/OR OTHERS.
• CONDUCTOR SIZE (AWG), LENGTH AND AMPACITY SHOULD BE TAKEN INTO CONSIDERATION
PRIOR TO DESIGN AND INSTALLATION OF THESE PRODUCTS, PARTICULARLY IN RETROFIT
INSTALLATIONS.
