AB-26
Audiobeam Fog Signal
AB-26 Audiobeam® is an electrically powered fog signal that automatically broadcasts a 360° beam of sound in the horizontal plane to a preselected code.
It is UL listed as suitable for use in Class I, Division 2, Group D hazardous locations and also certified for ATEX CAT3 EEx nL IIA locations. The AB-26 is United States Coast Guard approved. The IALA usual range for this fog signal is 1/2NM.
Characteristics
- ELECTRONIC CONTROL UNIT – Contained within the hinged top section are the electronic controls utilizing a patented solid-state power amplifier, a time delay circuit with three- position switch and a unijunction control-led timer. Timer uses Tideland’s OMNIBUS® circuitry technology, which allows two or more fog signal units to be synchronized to sound sequentially or in unison.
- ELECTRODYNAMIC DRIVER UNITS – A heavy-duty driver powers a dual resonant emitter. Enclosed in the AB-26 weatherproof housing, it is engineered for efficiency and long on-station life, operating at less than 25% of rated capacity.
- STRUCTURE – AB-26 structure is 5052-H32 aluminum with primer wash and Polane epoxy coating. The fog signal is completely assembled and wired, ready for field connection with 3/4-inch NPT cable entry and six 3/4-inch NPT UL-Listed NavGrip®
- POWER – AB-26 is designed for unattended operation from a source of 12 volts DC primary or secondary energy cells. It can be operated from Tideland’s SolaViva® solar power generator, or from mains power using a Tideland Signal power supply or charger and secondary energy cell.
