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).

Application
1. The chimes are factory set in single stroke (SS) mode. They can be
changed to vibrating (VIB) mode with jumper on PC Board. SINGLE STROKE
OPERATION: The minimum input pulse duration must be at least 160 ms “on”
time and 160 ms “off” time. The chime will only operate once each time it is
pulsed. This mode is recommended for coded systems. VIBRATING OP-
ERATION: Continuous input voltage applied to the chime will activate the
chime at one-second intervals.
2. The volume and tone controls have been adjusted at the factory to insure
maximum dBA output. However, once the mode is selected, the installer
may want to fine-tune the signal to better suit the application.
3. Anechoic dBA is measured in an anechoic chamber with peak meter re-
sponse. Reverberant dBA is rated per UL Standard 464.
4. Chime inrush current is 0.100 amps maximum with filtered DC input (0.140
amps with VRMS input voltage) with a time duration of 100 milliseconds.
