Alpha DZ209/5 5-Diode Board Assembly with Tape

Reduce installation complexity and improve access-panel reliability with the Alpha Communications DZ209/5 5-Diode Board Assembly. Designed for 2-wire intercom and NoCoax video entry applications, this compact diode board lets standard pushbuttons act as common wires when idle, minimizing dedicated conductors and simplifying multi-tenant installations. The DZ209/5 supports five pushbuttons using five diodes, ships with self-stick tape for convenient placement inside lobby entry stations, and measures just 1.8" x 0.6" x 2.3" for tight panel fits. Fully compatible with Alpha HT2009 and HT3009 handset systems as well as 5661/000 video-intercom systems, it’s ideal for property managers, integrators, and security professionals building or retrofitting intercom, access control, or surveillance-ready entry systems. By isolating each button circuit, the board reduces false triggers and improves signaling reliability—critical for secure access and monitoring. Match DZ209/5 and DZ209/10 boards as needed for custom button counts. Add the DZ209/5 to your next lobby or gate entry build to streamline wiring and enhance system performance.

• Simplifies lobby entry wiring by enabling standard pushbuttons to share common lines, reducing installation time and cable runs
• Compatible with Alpha Communications HT2009, HT3009 and 5661/000 systems for seamless integration into 2-wire intercom and video entry setups
• Includes self-stick tape for fast, tool-free mounting inside entry panels and tight enclosures
• Modular 5-diode design supports up to 5 pushbuttons and can be mixed with DZ209/10 boards for scalable multi-button panels
• Improves system reliability by isolating button circuits with diodes to prevent cross-talk and ensure clear signaling for access control and monitoring
