www.cooperwheelock.com    SERIES S8 EIGHT INCH SPEAKER AND MULTI-CANDELA SPEAKER STROBE 

     (CEILING MOUNT VERSION)

 

 

Use this product according to this instruction manual.  Please keep this instruction manual for future reference. 

GENERAL: 

Wheelock’s Series S8-70/25 Eight Inch Speaker, S8-24MCC Multi-Candela Eight Inch Speaker Strobe and S8-24MCCH Multi-High Candela are UL Listed under 
Standard 1971 (Signaling Devices for the Hearing Impaired) and Standard 1480 (Speakers for Fire Protective Signaling Systems) for indoor fire protection service.  The 
S8 Eight Inch Speaker is designed for multiple power requirements with high dBA output at each power tap and offers a choice of field selectable taps, 1/4W to 8W for 
either 25.0VRMS or 70.0VRMS audio systems.  The speaker has a molded, flame retardant cone. 

 

NOTE

:  In order to maintain proper UL 1480 listing, the CBB-8 Speaker Backbox (available separately) must be installed.  The CBB-8 Backbox is required for  use in 

ceiling plenums that are part of return air handling systems. 

 

The S8-24MCC Strobe provides four selectable light output intensities (15,30,75,95cd) in one unit.  The S8-24MCCH Strobe provides two selectable light intensities 
(115,177cd) in one unit. The Strobe can provide a non-synchronized strobe appliance when connected directly to a fire alarm control panel (FACP), or provide a 
synchronized strobe appliance when used in conjunction with a Sync Module (SM), Dual Sync Module (DSM) or Wheelock’s Power Supplies.  The strobe uses a xenon 
flashtube with solid state circuitry enclosed in a polycarbonate lens to provide maximum visibility and reliability for effective visible signaling.  The S8-70/25, S8-
24MCC and S8-24MCCH are Listed for 

indoor use, ceiling mount only

 with the backboxes specified in these instructions (see wiring and mounting information). 

WARNING:  PLEASE READ THESE INSTRUCTIONS CAREFULLY.  FAILURE TO COMPLY WITH ANY OF THE FOLLOWING 

INSTRUCTIONS, CAUTIONS AND WARNINGS COULD RESULT IN IMPROPER APPLICATION, CANDELA SETTING, 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.

NOTES: 

1. 

The strobe will produce 1 flash per second over the "Regulated Voltage" range. 

2. 

The strobe meets the required light distribution patterns defined in UL 1971.   

3. 

The Series S8-70/25, S8-24MCC and S8-24MCCH are UL Listed for indoor use with a temperature range of +32

°

F  to +120

°

F  (0

humidity of 85% RH. 

4. A 

10

µ

F blocking capacitor for DC supervision of audio lines by the FACP is factory wired in series with the speaker input.  The

 

maximum supervision voltage is 

33 volts DC.   Frequency range of speakers is 400-4000Hz. 

 

WARNING:  THESE APPLIANCES WERE TESTED TO THE REGULATED VOLTAGE LIMITS OF 16.0-33.0 VOLTS FOR 24V MODELS USING 

FILTERED DC OR UNFILTERED FULL-WAVE-RECTIFIED VOLTAGE.  DO NOT APPLY VOLTAGE OUTSIDE OF THIS RANGE.

  

 

WARNING:  CHECK THE MINIMUM AND MAXIMUM OUTPUT OF THE POWER SUPPLY AND STANDBY BATTERY AND SUBTRACT THE 

VOLTAGE DROP FROM THE CIRCUIT WIRING RESISTANCE TO DETERMINE THE APPLIED VOLTAGE TO THE STROBES.  THE MAXIMUM 
WIRE IMPEDANCE BETWEEN STROBES SHALL NOT EXCEED 35 OHMS.  

 

WARNING:  CANDELA SETTING WILL DETERMINE THE CURRENT DRAW OF THE PRODUCT.

WARNING:  MAKE SURE THAT THE TOTAL RMS CURRENT REQUIRED BY ALL APPLIANCES THAT ARE CONNECTED TO THE 

SYSTEM’S PRIMARY AND SECONDARY POWER SOURCES, NAC CIRCUITS, SM, DSM SYNC MODULES OR WHEELOCKS POWER SUPPLIES 
DO NOT EXCEED THE POWER SOURCES’ RATED CAPACITY OR THE CURRENT RATINGS OF ANY FUSES ON THE CIRCUITS TO WHICH 
THESE APPLIANCES ARE WIRED.  OVERLOADING POWER SOURCES OR EXCEEDING FUSE RATINGS COULD RESULT IN LOSS OF POWER 
AND FAILURE TO ALERT OCCUPANTS DURING AN EMERGENCY, WHICH COULD RESULT IN PROPERTY DAMAGE AND SERIOUS INJURY 
OR DEATH TO YOU AND/OR OTHERS. 

When calculating the total currents:  Use Table 2 to determine the highest value of “RMS Current” for an individual strobe (across the expected operating voltage range 
of the strobe), then multiply these values by the total number of strobes; be sure to add the currents for any other appliances, including audible signaling appliances, 
powered by the same source and include any required safety factors. 

NOTE:  

The maximum number of strobes on a single notification appliance circuit shall not exceed 50. 

CAUTION:  

The

 

Strobe is not designed to be used on coded systems in which the applied voltage is cycled on and off.
