  • Features

    Electronic Control Unit
    Contained within the hinged top section are the electronic controls utilising a patented solid-state power amplifier, a time delay circuit with threeposition switch and a unijunction control-led timer. Timer uses Tideland’s OMNIBUS® circuitry technology, which allows two or more fog signal units to be synchronised to sound sequentially or in unison.

    Electrodynamic Driver Units
    A heavy-duty driver powers a dualresonant 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
    The AB-26 structure is 5052-H32 aluminium 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.
