General Notes

• Strobes are designed to flash once 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 min. effective Strobe intensity per UL Standard 1971.

• Series ET Speaker Strobes and Series ET Speakers are listed under UL Stan-

dard 1971 for indoor use with a temperature range of 32°F to 120°F (0°C to 49°

C) and maximum humidity of 85%.

• Cooper-Wheelock Weatherproof Appliances are designed to operate over an

extended temperature of of -31° F to 150°F (-35°C - 66°C) and all candela rat-

ings 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

voltage range. Prior to this change, UL used the term, “Listed Voltage Range”.

Engineer’s Specifications

The speaker appliances shall be Cooper-Wheelock Series ET Speakers and

speaker strobe appliances shall be Cooper-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

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.

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 produces a flash rate of one (1) flash per sec-

ond over the Regulated Voltage Range and incorporates a Xenon flashtube en-

closed in a rugged Lexan® lens. The strobe is of low current design. If, Multi-

Candela Speaker Strobes are specified, the strobe intensity has field selectable

settings and is 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 the candela is tamper resistant. The 15/75 strobe is specified when 15 candela

UL Standard 1971 listing with 75 candela on-axis is required (ADA compliance).

When synchronization is required, the strobe portion of the appliance is compatible

with Cooper-Wheelock’s SM, DSM sync modules or power supply with built-in Coo-

per-Wheelock Patented Sync Protocol. The strobes do not drift out of synchroniza-

tion during operation. If the sync module or Power Supply fails to operate,

(i.e.,contacts remain closed), the strobe reverts 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 incorporates 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 or red plate. All speakers and speaker strobes shall be backward compatible.

Cooper-Wheelock products must be used within their published specifications and

must be PROPERLY specified, applied, installed, operated, maintained and opera-

tionally tested in accordance with their installation instructions at the time of instal-

lation and at least twice a year or more often and in accordance with local, state

and federal codes, regulations and laws. Specification, application, installation,

operation, maintenance and testing must be performed by qualified personnel for

proper operation in accordance with all of the latest National Fire Protection Asso-

ciation (NFPA), Underwriters’ Laboratories (UL), National Electrical Code (NEC),

Occupational Safety and Health Administration (OSHA), local, state, county, prov-

ince, district, federal and other applicable building and fire standards, guidelines,

regulations, laws and codes including, but not limited to, all appendices and

amendments and the requirements of the local authority having jurisdiction (AHJ).
