Product description

Electromechanical locking systems GN 120.4 are used together with latches GN 115 or GN 515. In the closed position, the latch arm is locked by the locking catch and by an electrical input signal. In addition, the presence of the latch arm in the closed position is detected and emitted as an output signal.

The locking system can be used for left or right locks and increases the latch distance A by 8 mm. Existing installations can be upgraded with minimal effort. The electromechanical locking system is also not visible from the outside.

Operation description


						If the latch arm is moved to the closed position via the rotation limited to 90°, the spring-loaded locking catch snaps forward to prevent reopening of the cam latch.
						In the closed position, the presence of the latch arm is detected by the latch arm check, and a high signal is output at the latch arm check output (pin 4) if a connection is also present between the additional contact pins 5 and 6. For example, this can take the form of a simple wire bridge or a door position check.
						To release the latch again, a high signal is applied to control input pin 4, causing the locking catch to be withdrawn electromechanically. In the event of a power failure or system fault, the locking catch can be pushed back via the manual emergency release. The emergency release is designed to allow the fastening of a Bowden cable.
						When the high signal at control input pin 4 falls away, the locking catch is released by the electromechanical mechanism, allowing the spring to push it forward again into the initial position.

Technical and assembly instructions

After installation, the connection cable can be additionally secured by a cable tie at the strain relief if necessary. The electromechanical locking system GN 120.4 can be easily added to existing
installations. To accommodate the electromagnetic locking system, it is only necessary to increase the latch distance A of the latch by 8 mm. Corresponding latch arms are available for all typical latch distances.
