To answer the challenge of security and life safety in today’s classroom environment, MARKS USA Custom Lockset Division has developed the Loc-Down™ Classroom Intruder ANSI/BHMA F110 Function Leverset with Clutch Design (MARKS USA Function DB). MARKS USA has incorporated all of the standard features of their Survivor Series Locksets (Clutch System, Super Strength Retractor, Long Life Lever Support Springs and a Life Test of over 3 Million Cycles) with their new Life Safety Classroom Intruder Function.
At the first sign of trouble outside, lock down a classroom instantly with Marks USA's Loc-Down™ Intruder locksets. Typical classroom function cylindrical locksets are designed to be locked or unlocked from the exterior with the interior always in an open position, but allows in emergency life safety situations the teacher to secure the classroom without stepping into the hallway to lock the outside handle. Faculty and students remain safely within the classroom. There is no need to open the door, the exterior lever is disables by operating the interior lock cylinder.
