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 its 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!
Securitron LMD-1 Latch Monitor for Aluminum Door Deadlock
The Deadlock Monitor is employed with an Adams Rite MS type deadlock or similar lock from an alternate manufacturer to report on the locked or unlocked status of a narrow stile door (usually aluminum frame glass). The LMD-1 provides an SPDT dry output to an alarm system or other monitoring device. It provides higher security assurance than the more commonly employed magnetic contacts which report a door as "closed" when it may still be unbolted. The LMD-1 installs easily in the door frame stile without the need for any routing.
