AB105LDA Alarm Horn Sounder & LED Beacon 2-31-170

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.
