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 minimum effective Strobe intensity based on UL

Standard 1971.

•

Series E Speaker Strobes and Series E Speakers are listed under UL Standard

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

and maximum humidity of 85%.

•

“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”.

Engineering’s Specifications

The chime appliances shall be Wheelock Series CH Chimes and the chime strobe

appliances shall be Wheelock Series CH Chime Strobes or approved equals. The

chime shall be UL Listed under Standard 464 for Audible Signal Appliances and

chimes equipped with strobes shall be listed under UL Standard 1971 for Emergency

Devices for the Hearing-Impaired. In addition, the strobes shall be certified to meet

the requirements of FCC Part 15, Class B and shall incorporate low temperature

compensation to ensure the lowest possible current consumption.

All chimes shall use solid state components and shall provide field selectable single

stroke or vibrating operation with volume control and tone control. All models shall

have a peak Anechoic sound output of 83 dB at 10 feet and an adjustable frequency

range of 800 to 1200 Hz. 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 Chime Strobes are specified, the strobe intensity shall have a mini-

mum of four (4) field selectable settings and shall be rated per UL Standard 1971 at:

15/30/75/110cd or 135/185cd for wall mount and 15/30/75/95cd or 115/177cd for

ceiling mount. The selector switch for selecting the candela shall be tamper resistant

and not accessible from the front of the appliance. The 1575 candela 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 com-

patible with Wheelock’s SM, DSM sync modules or any power supply with built-in

Patented Wheelock Sync Protocol. The strobes shall not drift out of synchronization 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 chime and the chime strobe appliances shall be designed for indoor surface or

flush mounting. The chime and chime strobe shall incorporate a chime 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.

All chime and chime strobe appliances shall be backward compatible.

Wheelock products must be used within their published specifications and must be PROPERLY

specified, applied, installed, operated, maintained and operationally tested in accordance with their

installation instructions at the time of installation 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 Association (NFPA),

Underwriters’ Laboratories (UL), National Electrical Code (NEC), Occupational Safety and Health

Administration (OSHA), local, state, county, province, district, federal and other applicable building

and fire standards, guidelines, regulations, laws and codes including, but not limited to, all appen-

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