Series S 8” Ceiling Speakers and Speaker Strobes
Description
The Wheelock Series S Speakers and Speaker Strobes are designed for high efficiency sound output, with dual voltage (25/70
VRMS) capability and field selectable taps from 1/8 to 8 watts.
The Series S Speaker Strobe models incorporate the Low Current
draw Series RSS Strobes. Strobe options for ceiling mount models
include 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.
Series 8 Speakers and Speaker Strobes provide high audio
output with clear audibility and are designed to meet the critical
needs of the life safety industry for effective emergency voice
communications, tone signaling and visible signaling to alert the
hearing impaired.
The strobe portion of all Series S Speaker Strobes may be
synchronized when used in conjunction with the Wheelock SM,
DSM Sync Modules or Wheelock PS-24-8MC Power Supplies
with Patented Sync Protocol. Wheelock synchronized strobes offer
an easy way to comply with ADA recommendations concerning
photosensitive epilepsy.
Series S Speaker Strobes are UL Listed for indoor use under
Standard 1971 (Signaling Devices for the Hearing-Impaired) and
Standard 1480 (Speaker Appliances), and use a Xenon flashtube
with solid state circuitry enclosed in a rugged Lexan® lens to
provide maximum reliability for effective visual signaling. All
inputs are supervised and employ IN/OUT wiring terminals for fast
installation using #12 to #18 AWG wiring.
The Series S, 8” Ceiling Speakers and Speaker Strobes are
available in three configurations:
S8-70/25 - Dual Voltage, multi-tap speaker
S8-24MCC - Speaker strobe with field selectable settings of
15/30/75/95cd
S8-24MCCH - Speaker strobe with field selectable candela settings
of 115/117cd

NOTE: All CAUTIONS and WARNINGS are identified by the symbol . All warnings are printed in bold capital letters.
WARNING: PLEASE READ THESE SPECIFICATIONS AND ASSOCIATED INSTALLATION 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 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 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”.

/8, ¼, ½, 1, 2, 4, 8 wattage taps. The frequency response shall be 200Hz 15kHz, per UL Standard 1480 shall be 400Hz 4kHz. The
sensitivity shall be 93 dBA @ 10 feet with 8 watts of source power, 90 dBA @ 10 feet with 4 watts of source power, 87 dBA @ 10 feet
with 2 watts of source power, 84 dBA @ 10 feet with 1 watts of source power, 81 dBA @ 10 feet with 1/2 watt of source power, 78 dBA
@ 10 feet with 1/4 watt of source power, 75 dBA @ 10 feet with 1/8 watt of source power. The magnet weight shall be 9.5 ounces. The
speaker impedance shall be 8 ohms.
The Speaker Strobe versions shall be Wheelock Series RSS Strobe Appliances or approved equals. The Series RSS shall meet and
be listed for UL Standard 1971 (Emergency Devices for the Hearing-Impaired) for Indoor Fire Protection Service. The strobe shall be
listed for indoor use and shall meet the requirements of FCC Part 15 Class B. The strobe appliances 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. All
inputs shall be compatible with standard reverse polarity supervision of circuit wiring by a Fire Alarm Control Panel (FACP).
The Series RSS Strobe shall be of low current design. The strobe intensity shall have field selectable settings and shall be rated per
UL Standard 1971 at 15/30/75/95cd or 115/177cd.
When synchronization is required, the appliance shall be compatible with Wheelock’s SM, DSM Sync Modules or Wheelock’s PS-12/248CP and PS-12/24-8MP Power Supply with built-in Patented Wheelock Sync Protocol. The strobes shall not drift out of synchronization
