SDC EH301224A Surface Mount Electric Strike

Overview

The SDC EH301224A is a surface-mounted electric strike designed for access control system integration. This unit operates on 24VAC power and mounts directly to standard door frames without requiring mortise cuts — a significant advantage in retrofit installations where frame modification is costly or restricted. The electromagnetic design holds doors securely while allowing remote release via access control panels or life-safety command centers. Zinc alloy construction resists corrosion in moderate indoor environments. The EH301224A accommodates 30 doors in a single system deployment, making it suitable for small-to-mid-scale facility access control.

Compatibility

The EH301224A integrates with access control systems and readers that support electromagnetic strike control via standard relay or solenoid activation circuits. Surface mount form factor fits standard hollow metal and wood door frames with minimal frame preparation. The 24VAC supply requirement means it operates from standard low-voltage power supplies common in access control installations — verify your control panel's strike relay capacity (typically 1–2A per strike) before wiring multiple units. No specific reader technology restrictions are noted in the evidence, but strike control is relay-based rather than credential-aware — the strike responds to electrical command from your panel, not directly to card or credential presentation.

Installation Notes

Surface mount installation requires drilling pilot holes into the door frame and securing the strike body with provided fasteners. The 4 5/8-inch projection extends from the frame to accommodate standard deadbolt throws. Ensure 24VAC power and control wiring are run to the strike location before final mounting. The single coil design provides field-selectable holding force — consult your control panel documentation and door weight specifications to confirm the holding force is adequate for your application. Zinc alloy construction is suitable for indoor dry environments; do not install in direct-weather exposure without additional protective housing.
