Simplex 4903 Horn-Visible Units - Installation Instructions

4903 Horn Visible Units Instructions and Warnings NOT INSTALL ANY SIMPLEX PRODUCT THAT APPEARS DAMAGED Upon unpacking your Simplex product inspect the contents of the for shipping damage If damage is apparent immediately file a claim with the carrier and notify Simplex HAZARD Disconnect electrical power when making any internal adjustments or repairs Servicing should be by qualified Simplex Representatives HAZARD Static electricity can damage components Therefore handle as follows Ground yourself before opening or installing components Keep uninstalled component wrapped in anti static material at all times use the 553 484 Static Control Kit 4903 Horn Visible Units are Notification Appliances listed by Underwriters Laboratories UL Notification Appliances provide an audible and or visible indication of an alarm condition when activated from the control panel of a UL listed Simplex Protective Signaling System When Notification emit sound and or flash a light they indicate the possibility of an emergency situation that requires your immediate attention Horn Visible Units have a switch to select Free Run or Synchronous operation of the strobe appliance Selecting Free Run has the strobe flash at a rate determined by a timer circuit in the strobe Selecting Synchronous operation forces the strobe to flash whenever the NAC voltage to zero Safety and Placement of Notification Appliances appliances and the fire alarm system itself have certain limitations and requirements for safety placement installation and test Since you must the limitations and adhere to the requirements keep these instructions at a central location for future reference so that all people who use maintain and the fire alarm system have access to this information appliances do not sense any hazardous conditions such as smoke fire explosion etc they are activated by a control panel as part of a system does sense such conditions appliances do not provide their own power They receive their power from the fire alarm system If power is not supplied to the notification for whatever reason the notification appliances will not provide an audible visible warning THEREFORE BACK UP POWER SUPPLIES OR BACK UP POWER SOURCES ARE REQUIRED FOR THE FIRE ALARM SYSTEM appliances provide a specific rated output level of sound or light The output level must meet the requirements of the intended protected Although the 4903 notification appliances meet the current UL standards for sound output and light intensity the protected area s may have walls carpeting furniture insulation or other obstacles that reduce or even block the sound and or light For all applications the sound and light output must enough intensity to alert all occupants of the protected area s including those occupants that are sleeping or hearing impaired for whatever reason If occupants cannot hear and or see the effect of the notification appliances within the protected area s you must increase the intensity of the sound light or add additional notification appliances so that the occupants can hear an or see the effect of the notification appliances when activated Refer to Fire Protection Association NFPA National Fire Alarm Code 72 Chapter 4 appliances are not a substitute for insurance coverage All users should have adequate levels of life and property insurance install maintain and test notification appliances within their specifications Failure to follow all safety precautions and instructions may result in of life and property due to non functioning notification appliances notification appliances use high voltage To avoid electrical hazards and avoid damage to appliances make sure that the electrical power for the Appliance Circuit is disconnected at the control panel before installing repairing or internally adjusting any notification appliances with electrical power removed some notification appliances such as visible strobes store a high voltage charge The high voltage can cause injury in death from electrical shock DO NOT TOUCH EXPOSED CIRCUITRY placement of notification appliances must conform to appliances are not intended for installation within hazardous locations as defined by the National Electrical Code NEC or the NFPA Contact for information on explosion proof notification appliances designed for hazardous environments candela rating of
