Horn Speaker


The Redback C2053 10W, 100 Vrms Horn Speaker offers a high degree of speech articulation and program clarity, essential to meet today’s demanding evacuation standards. Although the C2053 Speaker is suitable for general paging applications, it was primarily designed for Emergency Evacuation Systems. Supplied with an in-built bipolar capacitor, it is compatible with EWIS Control Systems utilising line-monitoring circuitry. It is also fitted with a 4-core termination lead to provide connection points for Loop In, Loop Out wiring, as required by Australian Standards.
