Fermax 3093 - Lock Release 300AD-412-S

Compact and silent electric strike with 412 compatibility for streamlined entry system fitting.

Fermax 30938 Electric Lock Release 300AD-412-S Max (12Vdc Automatic Fail Secure, Short Shield)

The Fermax 30938 combines automatic re-locking, fail-secure operation, a short shield, and an adjustable latch in an electric lock release designed for 12V DC systems. The designation indicates: 300 series body, AD operation (Automatic Fail Secure DC), 412 voltage (12V DC), S type short shield, and MAX adjustable latch. It does not have a manual override.

Key features detailed: The 300 series body. AD operation means it is Automatic Fail Secure for DC – locked without power, unlocks on a 12V DC (412) pulse, and mechanically re-locks automatically only after the door has been opened and closed. This prevents the door being left unlocked accidentally. The S shield is the *short* version (approx 25x120mm) for frames with restricted space. The MAX adjustable jaw allows +/- 4mm tuning for perfect latch alignment, ensuring secure locking and preventing rattle.

This model is ideal for 12V DC installations needing automatic re-locking security, fail-secure functionality, and where a short strike plate is required. The addition of the MAX adjustable latch provides valuable installation flexibility, making it easier to achieve a precise fit, especially in retrofit scenarios or with non-standard frame preparations.
