General

The Wheelock Series CH Chimes and Chime Strobes mini­mize alarm system power supply requirements and wiring
costs with a low current dra w and a pate nted chim e moun ting
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 field­selectable candela settings of 15/30/75/1 10 cd or the high­intensity 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 Signal­ing 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 reverse­polarity supervision.

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 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.

DN-3468:A • 02/28/07 — Page 1 of 4

• Series NS Strobe prod ucts are listed under UL Standard
1971 for indoor use with a temperature ra nge 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

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 OPERATION: Continuous input voltage

Average RMS Current

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 response. Reverberant dBA is rated per UL
Standard 464.

4. Chime inrush current is 0.100 A maximum with filtered
DC input (0.140 A with V

RMS 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.
