By electronically verifying mechanical latch and bolt positions, Securitron LM Series latch monitors detect and report to the building alarm or access control systems that a door is actually latched or bolted, not just closed. They install easily, are concealed behind exiting hardware, and require no jamb or strikeplate modification.
Three models in two sizes accept all North American latches or bolts. The innovative patented design automatically copes with variations between different brands of latching hardware without requiring installer adjustments. The LMS-1 includes a single SPDT switch and fits any standard 2-3/4” ANSI cut-out. The LML-1 also has a single SPDT switch and fits any standard 4-7/8” ANSI cut-out. The LML-2 monitors a mortise latch and deadbolt separately, features two separate SPDT switches, and fits any standard 4-7/8” ANSI cut-out.
When monitoring hook or swing bolts, conventional magnetic contacts report a door as simply closed, without confirmation that it’s secure. The deadlock monitor model LMD-1 can be used with an Adams Rite MS type deadlock or similar brand to report the locked or unlocked status of narrow stile aluminum frame doors, including sliding glass doors. And the LMD-1 installs quickly in door frame stiles without routing – just three holes to drill!
