Alarm Horn Sounder & LED Beacon

Upgraded Product:

  • New enhanced version
  • 64 alarm tones
  • 4 remotely activated alarm stages
  • Low in-rush electronics
  • Auto-synchronised horn and beacon
  • Pluggable, duplicated cable terminals
  • Dual cable entries with stopping plugs

Description

The low current consumption and high SPL in a robust fire retardant enclosure ensure the AB105LDA is suitable for all general signalling applications. The alarm horn sounder & LED beacon may be connected from a single or separate supplies for simultaneous or independent operation. The DC voltage versions feature 6 user selectable flash modes including rotating, flashing and steady. An alternative second stage beacon mode can be remotely activated via a third wire (as can alternative alarm tones on the horn sounder) enabling an audible and visual communication of a two stage alarm condition.
