New addressable Sounders - 420 Series from Bosch with advanced features

ST_FNS_420_Series_keyv.jpg
A new series of LSN improved Sounders that offer a high degree of flexibility by allowing installation of an acoustic alarm only, combined fire detection and acoustic alarm or acoustic plus an optical (strobe) alarm.

Innovation

  • Possibility to connect up to 100 sounders per loop
  • Constant sound pressure level even in case of voltage drop
  • Low current consumption of less than 4 mA
  • Immediate and permanent synchronization
  • Quick and easy ‘click-in’ installation
  • LSN improved version: The standard Bosch connection technology for both fire and intrusion systems

Benefits

  • The constant sound pressure level (SPL) simplifies the projection and planning
  • The low current consumption allows cost-effective solutions
  • Simplified planning and installation of fire alarm systems
  • High flexibility by mounting: 
           - acoustical alarm only 
           - fire detection and acoustical alarm  
           - acoustical and optical annunciation
  • Up to 100 sounders per loop

  • European tones covered

Base Sounder
  • Easy installation (sounder snaps into pre-installed mounting plate)
  • Special mounting plate for surface mounted cabling    
  • Installation costs reduced by mounting detectors or beacons into the base sounder
  • Subtle and low profile    
Stand-alone Sounder Indoor/Outdoor
  • Very high, consistent sound pressure level at low power
  • Easy Installation (comfortable black box with knock-outs and space for cabling)
  • Very robust design
Local Security Network functionality
  • Master-slave principle, with all smoke detectors, remote indicators, fire alarm devices, intrusion detectors, keypads, arming devices and sounders connected to it
  • Flexible structure with loop, stub or tree-off configurations
  • Additional extension by interfaces with inputs and outputs and zone expanders
  • Power and data transmission via two wires

Features

  • 2 types: red and white
  • 90 dB with current < 4 mA
  • Constant sound pressure level in case of voltage drop
