SDC EHRA15A 1.5" Adjustable Extended Rod
Overview
The EHRA15A is a 1.5-inch adjustable extended rod strike assembly designed for multi-door access control installations where door frames or security requirements demand rod-based locking. This accessory integrates with enterprise access control systems that use OSDP-compliant readers and TCP/IP network communication. The adjustable rod length accommodates retrofit and new-build scenarios where standard strike plates are insufficient — typical in high-security corridors, server rooms, or facilities requiring consistent fail-safe or fail-secure operation across multiple doors.
Compatibility
The EHRA15A pairs with access control platforms supporting OSDP protocol and TCP/IP communications. Verify that your readers output OSDP signals and that your control system supports mixed-credential environments (DESFire, MIFARE, NFC at 13.56MHz, and 125kHz Proximity). Compatible with systems managing up to 63 doors and 250,000-user credential databases — typical for mid-to-large enterprise deployments. If you're integrating retrofit installations, confirm door frame depth and existing strike mounting before ordering; adjustability mitigates minor frame variations but does not accommodate extreme offsets.
Installation Notes
Install the rod strike using standard screws rated for your door frame material (wood, aluminum, or steel). The 1.5-inch rod provides clearance for frames with shallow or angled edges. Ensure the strike aligns with the latch mechanism on the locking device — misalignment creates binding and premature wear. Wire connections to the strike control circuit must be rated for the strike's energization voltage and current draw; consult your access control panel documentation for circuit specifications. Test the strike in both energized and de-energized states before final commissioning to verify fail-safe or fail-secure behavior matches your security policy.
