Fermax Lock Release 540N-S Max

Fermax 30711 Electric Lock Release 540N-S Max (12Vac Fail Secure)

The Fermax 30711 is a standard electric lock release mechanism designed for 12V AC powered Fermax door entry systems, providing basic fail-secure operation with the benefit of an adjustable latch. The designation details are: 540 series standard body, N operation (Normal Fail Secure AC), S type standard shield, and MAX adjustable latch. It does not include automatic re-locking or manual override.

Key features explained: The 540 standard body fits common frame preparations. N operation indicates Normal Fail Secure for AC voltage – the lock remains secure without power. Applying a continuous 12V AC voltage unlocks the strike, allowing the door to open. Power removal instantly re-locks it. The S shield is the standard grey flush mounting plate (approx 25x160mm). The crucial MAX feature is the adjustable jaw, allowing +/- 4mm movement for precise alignment with the doors latch bolt, ensuring proper locking and preventing rattle.

This model is a reliable workhorse for standard 12V AC intercom systems (common in older or basic Fermax audio/video kits). It offers essential fail-secure functionality (locked on power failure) and the adjustable MAX latch simplifies installation, particularly useful in retrofit situations where frame/door alignment might not be perfect. it is suitable for a wide range of residential and light commercial applications.
