The Zeta motorised fire alarm bells combine styling and functional efficiency. They incorporate a low power rotary centrifugal mechanism, which gives a high sound output with low current consumption at 24V dc. The bells are available in 2 sizes; 6″ (152mm) and 8″ (203mm). These sizes suit a wide variety of installations. There is a 230V ac version of the 6″ bell, and a 24V dc Weatherproof version of the 8″ bell.
