Dormakaba Rci P-500-H-A-OSDP Proximity Reader Osdp

Product Description

The DORMAKABA USA INC. / RCI P-500-H-A-OSDP is a proximity card reader designed for access control applications. It communicates over the Open Supervised Device Protocol (OSDP), an industry-standard serial communication protocol that supports bidirectional communication between the reader and an access control panel. OSDP-capable readers offer enhanced security compared to legacy Wiegand-output devices, and this unit is suited for installation in commercial and institutional environments where supervised communication is required. Licensed security and low-voltage technicians are the primary installers.

This proximity reader is intended for use in commercial door access control systems where OSDP connectivity is specified. Typical applications include secured entry points in office buildings, data centers, healthcare facilities, and other environments requiring credential-based access management. The unit ships as a single reader (sold individually) and is positioned as a standard-form-factor device within the RCI proximity reader product line.

Key Features

• OSDP communication protocol for supervised, bidirectional reader-to-panel data exchange
• Proximity card credential reading for contactless access control
• Standard form factor suitable for typical commercial door frame and wall-box mounting
• Sold as a single unit for straightforward per-door deployment

Compatibility

Designed as an OEM-style proximity reader for commercial access control panels and controllers that support OSDP serial communication. No specific compatible panel model numbers were provided in the available product data.

Installation Notes

Installation should be performed by a licensed low-voltage or security systems technician in accordance with applicable local codes and NFPA 731. De-energize the access control panel and associated wiring circuits before connecting or disconnecting the reader. Follow the access control panel manufacturer's documentation for OSDP address configuration and supervised line settings. Do not install in locations exposed to direct moisture unless the unit is rated for that environment.
