WARNING:  MULTITONE STROBE APPLIANCES ARE NOT TO BE USED AS AN INDOOR VISUAL 

EVACUATION APPLIANCE OR FOR THE HEARING IMPAIRED. 

 

WARNING: IF MULTITONE STROBE APPLIANCES ARE OPERATED WITHIN 15 INCHES OF A PERSON'S EAR, 

THEY CAN PRODUCE A SOUND PRESSURE LEVEL THAT EXCEEDS THE MAXIMUM 120 dBA PERMITTED BY 
ADA AND OSHA RULES.  EXPOSURE TO SUCH SOUND LEVELS CAN RESULT IN DAMAGE TO A PERSON'S 
HEARING. 

 

WARNING: A SMALL POSSIBILITY EXISTS THAT THE USE OF MULTIPLE STROBES WITHIN A PERSON'S 

FIELD OF VIEW, UNDER CERTAIN CIRCUMSTANCES, MIGHT INDUCE A PHOTO-SENSITIVE RESPONSE IN 
PERSONS WITH EPILEPSY.  STROBE REFLECTIONS IN A GLASS OR MIRRORED SURFACE MIGHT ALSO 
INDUCE SUCH A RESPONSE.  TO MINIMIZE THIS POSSIBLE HAZARD, WHEELOCK STRONGLY RECOMMENDS 
THAT THE STROBES INSTALLED SHOULD NOT PRESENT A COMPOSITE FLASH RATE IN THE FIELD OF VIEW 
WHICH EXCEEDS FIVE (5) Hz AT THE OPERATING VOLTAGE OF THE STROBES (SEE TABLE 4).  WHEELOCK 
ALSO STRONGLY RECOMMENDS THAT THE INTENSITY AND COMPOSITE FLASH RATE OF INSTALLED 
STROBES COMPLY WITH LEVELS ESTABLISHED BY APPLICABLE LAWS, STANDARDS, REGULATIONS, 
CODES AND GUIDELINES. 

 

WARNING:  THE MULTITONE STROBE APPLIANCES MUST BE FIELD SET TO THE DESIRED dBA SOUND 

OUTPUT LEVEL AND ALARM TONE BEFORE THEY ARE INSTALLED.  THIS IS DONE BY PROPERLY 
INSERTING A JUMPER PLUG AND ADJUSTING A FOUR POSITION SWITCH IN ACCORDANCE WITH THESE 
INSTRUCTIONS.  INCORRECT SETTINGS WILL RESULT IN IMPROPER PERFORMANCE AND MAY DAMAGE 
THE PRODUCT. 

 

CAUTION:  Check the installation instructions of the manufacturers of other equipment 

used in the system for any guidelines or restrictions on wiring and/or locating 
Notification Appliance Circuits (NAC) and notification appliances.  Some system 
communication circuits and/or audio circuits, for example, may require special precautions 
to assure electrical noise immunity (e.g. audio crosstalk). 
 

These appliances can produce a distinctive three pulse Temporal Pattern Fire Alarm Evacuation Signal (for total evacuation) in 
accordance with NFPA 72, 1993 Edition. 
 

NOTE:

  This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the 

FCC Rules.  These limits are designed to provide reasonable protection against harmful interference in residential installation.  This 
equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, 
may cause harmful interference to radio communications.  However, there is no guarantee that interference will not occur in a 
particular installation.  If this equipment does cause harmful interference to radio or television reception, which can be determined by 
turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:  
1) Reorient or relocate the receiving antenna,  2) Increase the separation between the equipment and receiver,  3) Connect the 
equipment into an outlet on a circuit different from that to which the receiver is connected, and  4) Consult the dealer or an 
experienced radio/TV technician for help.
