Lock Functions

  • Apartment/Corridor function is where the latch bolt is operated by a lever from either side, except when the outside lever is made inoperative by a stop or mechanical means other than a key. The dead bolt is operated by a key outside or turn inside. A key outside operates both bolts. Operating the inside lever retracts both bolts and the outside remains locked. The latch bolt is deadlocked when outside lever is made inoperative or when the dead bolt is projected. When dead bolt is retracted, lever is unlocked by a stop or mechanical means other than key.
  • Classroom function is where the latch bolt is operated by a lever on either side EXCEPT when the outside lever is locked from the outside by a key.
  • Entrance/Office function is where the door is unlocked by a key from the outside when the outer lever is locked by a turn-button on the inside lever. The inside lever is always unlocked.
  • Passage function is where the latch bolt is operated by the lever from either side at all times. There is no locking function.
  • Privacy function features push-button locking. The lock can be opened from the outside with an emergency release. The inside push button can be released by turning the inside lever.
  • Storeroom function is where the latch bolt is operated by a key outside and the lever from the inside. The outside lever is rigid.
