LOCKSET FUNCTIONS

LOCKSET FUNCTIONS

Lever- and knobsets come with at least one of the following functions: passage, entrance, privacy, storeroom, classroom, classroom intruder, communicating, and institutional. In this post I will explain what each of these functions are, and provide an example of where one might find them in the field.

1. Passage

This function allows both the interior and exterior knob or lever to retract the latch. Knobsets with this function are commonly used on closet doors, doors with an exiting lockset, or on doors that do not require a lock, like for example a laundry room door.

2. Entrance

This function allows the user to lock the outside lever by pushing the inside button. Using the operating key or depressing the inside lever will unlock the outside lever. This function also allows the user to lock the outside lever by pushing and turning the inside button. In this function the outside lever is always locked; only the operating key will retract the latch. The inside lever always retracts the latch. Leversets with this function are typically used on office doors.

3. Privacy

This function allows the user to lock the outside knob by pushing the inside button. Using an emergency tool or turning the inside knob will unlock the outside knob. Knobsets with this function are typically used on bathroom doors.

4. Storeroom

This function maintains the outside lever in the locked position at all times. The latch can only be retracted by using the operating key or by depressing the inside lever. Leversets with this function can be used on entrance doors to low-rise apartment buildings, computer server rooms, or public washrooms at gas stations.

5. Classroom

This function allows the user to lock or unlock the exterior knob by using the operating key in the outside knob. The interior knob always retracts the latch. Knobsets with this function are typically used on classroom doors.

6. Classroom Intruder

During a lockdown situation, this function allows the user to lock the exterior lever by using the operating key in the interior lever, thus preventing them from having to open the door to secure their classroom. The interior lever allows for free egress. Leversets with this function are used on classroom doors.

7. Communicating

This function is very similar to the classroom intruder function. Knobsets with this function allow the user to lock or unlock either knob with the operating key. Knobsets with this function can be found in senior care facilities to prevent patrons from wondering away.

8. Institutional

This function is very similar to the storeroom function. Leversets with this function are always rigid. The operating key must be used in either lever to retract the latch. Leversets with this function can be found in correction facilities.

Before buying a lever- or knobset it is important to determine which operational function you require. The above is intended to help you make this decision.
