CAUTION:  

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 120dBA permitted by ADA and OSHA rules.  Exposure to such sound levels can result in damage to 
a person's hearing. 

 

WARNING: WHEN INSTALLING STROBES IN AN OPEN OFFICE OR OTHER AREAS CONTAINING 

PARTITIONS OR OTHER VIEWING OBSTRUCTIONS, SPECIAL ATTENTION SHOULD BE GIVEN TO THE 
LOCATION OF THE STROBES SO THAT THEIR OPERATING EFFECT CAN BE SEEN BY ALL INTENDED 
VIEWERS, WITH THE INTENSITY, NUMBER, AND TYPE OF STROBES BEING SUFFICIENT TO MAKE SURE 
THAT THE INTENDED VIEWER IS ALERTED BY PROPER ILLUMINATION, REGARDLESS OF THE VIEWER'S 
ORIENTATION.  FAILURE TO DO SO COULD RESULT IN PROPERTY DAMAGE AND SERIOUS INJURY OR 
DEATH TO YOU AND/OR OTHERS. 

 

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 6).  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. 

 

NOTE:  

NFPA 72/ANSI 117.1 conform to ADAAG Equivalent Facilitation Guidelines in using fewer, higher intensity strobes within 

the same protected area. 

 

These appliances can produce a distinctive three pulse Temporal Pattern Fire Alarm Evacuation Signal (For total evacuation in 
accordance with NFPA 72 1999 Edition. 

 

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).

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.
