Securitron LMS-1 Securitron LMS1 Latch Monitor for ANSI Strike, Single Switch

Ensure doors are actually latched — not just closed — with the Securitron by ASSA ABLOY LMS-1 latch monitor. Designed for security and access control professionals, the LMS-1 electronically verifies latch and bolt position to reduce nuisance alarms, improve incident verification, and strengthen perimeter monitoring. The LMS-1 uses a single SPDT switch to report precise latch status to alarm panels, access control systems, or delayed egress logic timers, operating on common 12V or 24V DC inputs. Installation is fast and discreet: the unit fits any standard 2-3/4" ANSI strike cutout and mounts concealed behind existing hardware with no jamb or strike plate modification, making it ideal for retrofits. Whether you’re integrating with surveillance, building automation, or life-safety systems, the LMS-1 provides clear, tamper-resistant feedback that improves situational awareness and lowers false alarm risk. Perfect for commercial entrances, healthcare, education, and multi-tenant facilities.
