The LSDB-600 is an electric dropbolt that is mounted on any door frame with a width of 1.75” (44.5mm) or more. In addition, when fully mor- tised, its compact design allows the lock to fit on frames with a depth of 1.75“ (44.5mm). The 5/8” (16mm) stainless steel bolt has a 5/8” (16mm) throw, making forced entries difficult. The lock uses a magnetic sensor to sense the door posi- tion, thus locking the door when the door is in the closed position, preventing potential tailgaters. The device comes standard at failsafe, and oper- ates on 12VDC, with an aluminum polished face plate cover inclusive.
