Fermax 450AD-S Universal Lock Release Automatic 12Vac

Fermax F-2820 Universal Lock Release 450AD-S Automatic 12Vac

The Fermax F-2820 is a flush-mounted electric lock release based on the universal MOD.450 mechanism. It is designed for installation in wooden or metal door frames and is activated remotely from a door entry telephone or monitor.

Type A Automatic 12Vac operation: the lock release is unblocked when it receives a 12Vac voltage pulse. The lock release is blocked again once the voltage is cut off and the door opens and closes again mechanically. For proper installation, the automatic lock pin must be pressed in 3 mm by the latch once the door is closed again.

The lock release is reversible (Right DIN or Left DIN) and symmetrical, allowing change of hand while maintaining body symmetry. It includes a manual unblocking lever (D type) which inhibits its function, allowing free access when required.

Supplied with an S-type grey metallic flush shield for access doors, dimensions 25 x 160 mm (H x V).
