effeff 709X801PZ---G44

The security lock with handle control 709X is designed for situations where the benefits of handle-controlled unlocking must be combined with the mechanical security requirements of lock models 309X and 409X. The integrated monitoring contacts can query essential locking statuses.

The bolt is forced back by the engaged external handle, allowing the double action latch to function without obstruction. When the door is closed, the control latch, along with the pre-tensioned cross control, ensures that the bolt is fully extended and the double action latch is blocked, enhancing security.

Panic side settings and the selection between fail-locked and fail-unlocked can be adjusted on the lock as needed.

Features include:

• Mechanical automatic locking system
• Mechanical follow-up control between double action latch and control latch
• Double action lock, DIN left
• Switchable panic side
• Changeable between fail-unlocked and fail-locked
• Burglary-resistant due to solid bolt with 20 mm throw
• Panic function – approval in accordance with EN 179 and EN 1125
• Suitable for fire doors
• Controllable external handle
• Changeover function for unlocking with a key from the outside
• Monitoring functions
• One piece security lock
• One operating manual

The locks in the 709X series have a separate follower and require an internal handle (or a panic bar) and an external handle. Actuation is always with DC voltage, and the lock is available for both 12 V and 24 V actuation. The coils are designed for a 100% duty cycle.
