SYS/HS Hooters(Hooter Cum Strobe)

Key Features and Descriptions:

  • Horn Strobe Combination:
    • These devices combine both an audible (horn) and a visual (strobe) alarm signal. This dual functionality is crucial for ensuring that everyone in a building is alerted to a fire, including those with hearing impairments.
  • Notification Appliance:
    • They serve as notification appliances, designed to alert occupants of an emergency.
  • Visual Signaling:
    • The strobe component provides a flashing light, meeting requirements for visual signaling devices, particularly those outlined in the Americans with Disabilities Act (ADA).
  • Audible Signaling:
    • The horn component produces a loud, distinct sound that is easily recognizable as a fire alarm.
  • Field-Selectable Settings:
    • A significant feature of the SYS-HS series is its field-selectable candela settings (for the strobe) and horn settings (for the audible output). This allows installers to customize the devices to meet the specific requirements of the installation environment.
    • Candela settings determine the intensity of the strobe’s light output.
    • Horn settings allow for adjustments to volume and tone.
  • Synchronization:
    • These devices often include built-in synchronization features, ensuring that multiple strobes in a system flash in unison. This is important for avoiding seizures in individuals with photosensitive epilepsy.
  • Installation Flexibility:
    • They are designed to be compatible with a wide range of back box sizes, simplifying installation.
  • Certifications:
    • These devices are UL Listed (Underwriters Laboratories) and often hold other certifications, ensuring they meet established safety standards.
  • Universal Fire Symbol:
    • They commonly employ the universal fire symbol, making them easily recognizable regardless of language.

Key Technical Specifications:

  • Operating Voltage:
    • Typically 16 to 33 VDC (24 VDC nominal).
  • Operating Temperature:
    • 0°C to 49°C (32°F to 120°F).
  • Humidity Range:
    • 10% to 93% non-condensing.
  • Sound Intensity:
    • ≥82 dBA (varies with settings).
  • Strobe Flash Rate:
    • 1 flash per second.
  • Candela Settings:
    • Field-selectable settings, commonly including options like 15, 75, and 115 cd.
  • Wiring:
    • Input terminal wire gauge: typically 14 to 18 AWG.
  • Dimensions:
    • Varies slightly depending on the exact model, but generally around 5.15″ L x 5.0″ W x 1.5″ D.

Key Features Related to Specifications:

  • Synchronization:
    • Built-in synchronization to keep strobes in sync, often for up to 30 minutes.
  • Audible Settings:
    • Field-selectable horn settings, including high and low volume, and continuous or temporal 3-tone options.
  • Visual Settings:
    • Field selectable candela settings.
  • Certifications:
    • UL Listed (UL 1638 for strobes, UL 464 for horns).

Important Considerations:

  • Always refer to the specific product datasheet for the most accurate and up-to-date technical specifications.
  • Ensure that installations comply with all applicable local and national codes.
  • UL Listings:
    • A primary certification is from Underwriters Laboratories (UL). This is crucial for fire safety equipment. Specifically, SYS-HS devices are typically:
      • UL Listed for audible signal appliances (UL 464).   
      • UL Listed for visual signaling appliances (UL 1638).   

       

    • These UL listings mean the devices have been rigorously tested to meet safety and performance standards.   
  • Other Potential Certifications:
    • Depending on the specific model and where it’s being used, SYS-HS devices may also have certifications from:
      • CSFM (California State Fire Marshal).   
      • MEA (NYC Department of Buildings Materials and Equipment Acceptance).
      • ULC (Underwriters Laboratories of Canada) for canadian applications.
  • ADA Compliance:
    • While not a “certification” in the same way as a UL listing, these devices are designed to comply with the Americans with Disabilities Act (ADA) requirements for accessible alarm systems. This involves meeting standards for strobe light intensity and flash rate.
