The SRC-612 EN is an EN 54-24:2008 certified A/B ceiling speaker, engineered for use in voice alarm systems (VAS) in accordance with DIN EN 50849, VDE 0828 and VDE 0833-4. Featuring two independent full-range drivers and two 100 V transformers in a single housing, it enables genuine A/B line separation while saving space – a key requirement in safety-critical installations.

Thanks to its compact depth of just 68 mm and an antistatic PET plastic rear cover, the SRC-612 EN is ideal for shallow ceiling cavities. Installation is quick via spring-clamp mounting, compatible with ceiling thicknesses of 3–45 mm. For added safety, the speaker includes two 2-pole ceramic terminals with thermal fuses, moisture-proofing, and operates within a wide temperature range.
