The beacon and sounder can be operated from the same power source or controlled individually.

The AB105STR Xenon beacon component features an automatically synchronised flash rate of 1Hz (60 flashes per minute) as standard. The DC voltage versions also have user selectable 1.5Hz (90 flashes per minute) and double-strike flash rates. The double strike flash rate can be remotely activated via a third wire (as can alternative alarm tones on the horn sounder) enabling a audible and visual communication of a two stage alarm condition.
