Sdc Security Door Controls MS-18 Mortise Lock Monitor

Product Description

The SDC Security Door Controls MS-18 is a mortise lock dead bolt monitor designed to provide electrical status feedback on the position of a dead bolt within a mortise lock body. The MS-18 detects whether the bolt is extended or retracted and sends that signal to an access control panel, alarm system, or building automation system. This type of monitor is a critical component in door hardware integration for facilities that require real-time lock-status reporting. It is installed by licensed locksmiths, security integrators, or low-voltage access control technicians working on commercial door hardware applications.

The MS-18 is suited for commercial and institutional environments where mortise lock dead bolt status must be monitored as part of an integrated access control or security system. Typical applications include office buildings, schools, healthcare facilities, and other commercial properties where door position and lock status are tracked electronically. The monitor installs within or alongside the mortise lock body and interfaces with the facility control infrastructure.
