D-BZR

RDL D-BZR – Piezo Alert Module with Audible and Visual Alarm

The RDL D-BZR is a compact piezo alert module designed for professional AV installations, security systems, and industrial applications requiring immediate notification of remote conditions. It generates a 4 kHz audible signal with a sound pressure level of up to 85 dB SPL at 10 cm, ensuring clear and effective alerts.

The module features an LED alarm indicator, a front-panel reset button, and remote reset capability. Users can select between momentary or latching operation and choose between loud or soft audio levels, allowing for flexible adaptation to various environments.

With simple TRIP and RESET control inputs (activated by grounding), the D-BZR integrates easily into AV control systems, building automation, or warning systems. Its compact size and 24 V AC/DC power requirement make it ideal for rack enclosures, control panels, and space-constrained installations.
