NOTIFIER Series CH Chimes and Chime Strobes
Audio/Visual Devices
General
The Wheelock Series CH Chimes and Chime Strobes minimize alarm system power
supply requirements and wiring costs with a low current draw and a patented
chime mounting plate for fast, easy installation. Each model has a built-in
level adjustment feature and an aesthetic two-screw grille cover.
These unique solid-state chime appliances provide field selectable single-
stroke or vibrating operation with Anechoic sound levels adjustable up to 83
dB and tone adjustable from 800 to 1200 Hz.
Strobe options for wall mount models include 15/75 candela or Wheelock
patented MCW multi-candela strobe with field-selectable candela settings of
15/30/75/110 cd or the high-intensity MCWH strobe with field-selectable
135/185 cd.
Ceiling-mount models are available in Wheelock patented MCC multi-candela
ceiling strobe with field-selectable intensities of 15/30/75/95cd, or the
high-intensity MCCH strobe with field selectable 115/177cd.
The strobe portion of all Series CH Chime Strobes may be synchronized when
used in conjunction with the Wheelock SM, DSM Sync Modules or the Wheelock
PS-24-8MC Power Supply with patented Sync Protocol. Wheelock’s synchronized
strobes offer an easy way to comply with ADA recommendations concerning
photosensitive epilepsy as well as meeting the requirements of NFPA 72 and
UFC.
The Series CH Chime Strobes are UL Listed for indoor, wall or ceiling mount
applications under Standard 1971 for Signal-ing Devices for the Hearing-
Impaired and under Standard 464 for Private Mode Audible Signal Appliances.
They are available in two attractive package styles for flush mounting to
standard electrical boxes or convenient surface mounting. All models include
IN/OUT wiring terminations that accept two 12 AWG to 18 AWG wires at each
terminal. Inputs are polarized for compatibility with industry standard
reverse-polarity supervision.

WARNING
PLEASE READ THESE SPECIFICATIONS AND ASSOCIATED INSTAL-LATION INSTRUCTIONS
CAREFULLY BEFORE USING, SPECIFYING OR APPLYING THIS PRODUCT. VISIT
WWW.COOPERWHEELOCK.COM OR CONTACT COOPER WHEELOCK FOR THE CURRENT INSTALLATION
INSTRUCTIONS. FAILURE TO COMPLY WITH ANY OF THESE INSTRUCTIONS, CAUTIONS OR
WARNINGS COULD RESULT IN IMPROPER APPLICATION, INSTALLATION AND/OR OPERATION
OF THESE PRODUCTS IN AN EMERGENCY SITUATION, WHICH COULD RESULT IN PROPERTY
DAMAGE, AND SERIOUS INJURY OR DEATH TO YOU AND/OR OTHERS.
General Notes
- Strobes are designed to flash at 1 flash per second mini-mum 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 NS Strobe products 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 93% (± 2%).
- Series NH horns are listed under UL Standard 464 for audible signal appliances (indoor use only).
- “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.”
Application Notes for Current Table
-
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 OPERATION: Continuous input voltage applied to the chime will activate the chime at one-second intervals. -
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.
-
Anechoic dBA is measured in an anechoic chamber with peak meter response. Reverberant dBA is rated per UL Standard 464.
-
Chime inrush current is 0.100 A maximum with filtered DC input (0.140 A with VRMS input voltage) with a time dura-tion of 100 milliseconds.
CHIME dBA RATINGS
Sound level for CH70/CH90 is 83 dBA @ 10 ft (3.048 m) anechoic room; dBA in a
10 ft (3.048 m) reverberant room is 52 dBA minimum to 58 dBA maximum.

NOTE: __ RMS current ratings are per UL average RMS method. UL
maximum current rating is the maximum RMS current within the Listed voltage
range (16-33Vfor 24V units). For strobes, the UL maximum current is usually at
the minimum Listed voltage (16V for 24V units). For audibles, the maximum
current is usually at the maximum Listed voltage (33V for 24V units). For
unfiltered FWR ratings, see installation instructions.

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
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 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 rugged 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 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
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 trim plate or adapter.
All chime and chime strobe appliances shall be backward compatible.
