AB121STR Alarm Sounder & Xenon Strobe

The AB121STR combines a heavy duty 126dB(A) alarm sounder with a powerful 15J Xenon strobe warning beacon featuring a single and double flash patterns.

The beacon and sounder can be operated from the same power source or controlled individually.
The AB121STR 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.
