The SDR-2R-INT internal sounder is ideal for those hard-to-reach areas out of earshot of keypads or panels - but where users need to hear system sounds. Designed with a discreet housing, the unit blends in easily in entrance halls and other aesthetically sensitive areas. What’s more, it offers the option of connecting via either a radio expander or control unit with built-in radio capability.
