Sargent 11-Line Cylindrical (bored) Lockset
Security in our elementary and secondary schools has become much more important. Schools across the country are implementing lockdown procedures in case of emergency. Lockdowns are achieved through the use of locks, and new lock functions have been developed for use in concert with existing lock functions to answer the need for increased security.
Classroom Security Locks
A regular, traditional classroom function lock is unlocked and locked from the outside by key and the inside lever is always unlocked, allowing free egress. The problem with this function from a lockdown point of view is that, in order to lock the door, the teacher must open the door to lock it, exposing themselves and potentially their students to danger as they do so.
All major lock companies are either developing a classroom security function or assigning that application to one of their existing functions. Basically, the principal is this: in the event of an emergency the teacher can lock the outside lever handle of the classroom door from inside the classroom, thereby securing the safety of the students without endangering themselves. The inside lever remains unlocked allowing free egress. When locked, entry from the outside is by key only.
Some companies have developed classroom security function locksets in which the outside lever can be locked or unlocked with either the inside key or the outside key. This allows the teacher to continue to use the lock as a traditional classroom lock unless an actual emergency develops.

Electric Lock Down Systems
Some school districts have opted to lock down their perimeter doors with delayed egress systems. Delayed egress systems are a way of locking exterior entrance doors from both sides while allowing for emergency egress.
