Architects’ and Engineers’
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 incorpo-
rate low temperature compensation to ensure the lowest pos-
sible current consumption.
All chimes shall use solid state components and shall provide
field selectable single stroke or vibrating operation with vol-
ume 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 AWG to 18 AWG wire sizes.
The strobe portion of the appliance shall produce a flash rate
of one flash per second over the Regulated Voltage Range
and shall incorporate a Xenon flashtube enclosed in a rug-
ged LEXAN® lens. The strobe shall be of low current design.
Where Multi-Candela Chime Strobes are specified, the
strobe intensity shall have a minimum of four field-selectable
settings and shall be rated per UL Standard 1971 at: 15/30/
75/110 cd or 135/185 cd for wall-mount models and 15/30/
75/95 cd or 115/177 cd for ceiling-mount models. The selec-
tor 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 Stan-
dard 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 SM, DSM sync
modules or the Wheelock PS-24-8MC Power Supply with
built-in Patented 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.
