HES 1500C-630 LM - Lock monitor - 1500C-630-LM

HES 1500C-630-LM Lock Monitor

When your access control system needs reliable feedback on physical lock status beyond just request-to-exit or door position, the HES 1500C-630-LM provides direct monitoring of the electric strike's bolt position. This lock monitor switch gives your panel real-time confirmation that the locking mechanism has actually retracted or engaged, not just that power was applied. Critical for high-security applications where you need to verify mechanical compliance, not just electrical state.

Key Features

• Direct mechanical monitoring of HES 1500 series strike bolt position
• 630 satin stainless finish matches HES 1500C-630 strikes for consistent appearance
• Form C dry contact output for universal panel compatibility
• Integrates into existing HES 1500C installations without strike replacement
• Provides independent lock status separate from RTE or DPS circuits
• Mechanical actuation ensures accurate status regardless of power conditions
• Field-installable on compatible HES 1500 series strikes

The 1500C-630-LM addresses a common gap in door hardware monitoring. REX sensors tell you someone wants out. Door position switches tell you the door opened. But neither confirms the strike bolt actually retracted when commanded. This monitor closes that loop, giving your access control panel definitive feedback on lock state. Particularly valuable in secure areas where tailgating is a concern, in elevator lobbies where you need to verify unlock before allowing car dispatch, or anywhere audit requirements demand mechanical confirmation of access events.

Installation integrates directly with HES 1500C series strikes. The monitor mounts to the strike body and actuates based on physical bolt movement. The dry contact output ties back to a supervised input on your panel, allowing you to log forced entry attempts, detect lock failures, or trigger alarms when bolt position doesn't match commanded state. The 630 satin stainless finish maintains aesthetic consistency across the strike assembly. For integrators deploying HES 1500 series hardware in applications requiring full electromechanical monitoring, the LM variant provides the verification layer your system design demands.
