Alarm Horn Sounder & Xenon Strobe

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

Low current consumption and high SPL in a outdoor rated robust enclosure ensure the AB112STR is suitable for all general signalling applications. Designed to withstand the harshest of environments the AB112STR employs the latest in reliable D Class amplifier technology for superior sound output with low current consumption. The alarm horn sounder & Xenon strobe beacon may be connected for simultaneous or independent operation. The Xenon beacon component features an automatically synchronised flash rate of 1Hz. The DC voltage versions also have user selectable 1.5Hz (90 flashes per minute) and double-strike flash rates.
