Fermax Lock Release 300AD-S

Fermax 2910 Electric Lock Release 300AD-S (12Vdc Automatic Fail Secure, Short Shield)

The Fermax 2910 is an electric lock release featuring automatic re-locking functionality and fail-secure operation, designed for 12V DC systems and notable for its short shield. The type code indicates: 300 series body (often associated with specific frame types or older standards), AD operation (Automatic Fail Secure DC), and S type shield (but in a shorter variant). It does *not* typically include the MAX adjustable latch or a manual override.

Key attributes include: The 300 series body might imply a slightly different form factor or legacy compatibility compared to the 540 series. AD operation means it is Automatic Fail Secure for DC voltage – locked without power, unlocks on a 12V DC pulse, and automatically re-locks mechanically only after the door has been opened and closed. The S designation here refers to a *short* standard flush shield, typically around 120mm in height and 25mm wide, often finished in grey. This shorter shield is used where frame preparation space is limited vertically.

This model is suitable for applications requiring the security of automatic re-locking and fail-secure operation on a 12V DC system, particularly where a standard length shield will not fit. Its lack of manual override enhances security in certain contexts. Ensure compatibility with the door frame preparation and the 12V DC power source from your Fermax system or access control panel.
