Classroom Intruder Cylindrical Lock with LED indicator | PDQ XGT135LED

Easy-to-Read LED Indicator Confirms the Door is Locked. XGT135 LED Classroom Intruder Cylindrical Lock is designed to allow a staff member to use the inside cylinder to lock the outside of the door, without compromising safety to the occupants in the room. But how does a staff member know if the outside lever is locked? Until now, it required opening the door and checking the lever. PDQ’s 135 LED Classroom Intruder function eliminates the need to open the door. Simply press the button on the lock, and…if the Red LED lights up, the outside lever is locked and secure. If the Red LED does not light up, this indicates the outside lever is not locked and secure.
