3F11/3F12 - Motorised Slam Action Lock

Application

Purpose

To provide secure locking of swinging doors or gates that can be unlocked from a remote location using third party security management systems (SMS) or by conventional key control. Designed to enable key and electric operation from one (3F11) or both (3F12) sides of the door.

Overview

The 3F11/3F12 are mortice locks of robust construction based on the Chubb Locks Custodial Services large mortice footprint. The locks are designed to deadlock automatically and to be unlocked electrically with bolt withdrawal by a motorised mechanism.

Specification

Unlocking

  • Electric Operation - Remote switch activates the locking solenoid and the locking dead bolt is withdrawn by the motor. When fully withdrawn the locking deadbolt is latched in position ready for the relocking operation.
  • Mechanical Operation - Locking mechanism is operated by a mechanical key that lifts the locking solenoid and withdraws the locking dead bolt. When fully withdrawn the locking dead bolt is latched in position ready for the relocking operation.

Locking

  • The lock automatically deadlocks when the door/gate is closed.
