Fermax 2909 300A-S Lock Release

Fermax 2909 Electric Lock Release 300A-S (12Vac Automatic Fail Secure, Short Shield)

The Fermax 2909 is an electric lock release featuring automatic re-locking and fail-secure operation, specifically designed for 12V AC systems and utilizing a short mounting shield. The designation indicates: 300 series body, A operation (Automatic Fail Secure AC), and S type short shield. It does not typically have a manual override lever and likely uses a standard (non-adjustable) latch.

Detailing the features: The 300 series body type. A operation means Automatic Fail Secure for AC voltage Ñ the lock is secure (locked) without power. Applying a 12V AC pulse unlocks it temporarily. It will then automatically re-lock mechanically only after the door has been physically opened and closed again, ensuring the door is secured after use. The S shield is the *short* version (approx 25x120mm), used when the door frame preparation has limited vertical space. The latch mechanism is typically standard (non-adjustable) in this model series.

This lock release is suitable for 12V AC powered Fermax intercom systems (common in many standard kits) where automatic re-locking functionality is desired for enhanced security, and where the frame requires a short strike plate. Its fail-secure nature ensures the door remains locked during power failures. Ideal for applications needing guaranteed re-locking without manual override.
