Locknetics GF3000 DSM Series Electromagnetic Lock, Mortise mounted, Fully concealed shear lock, Door Status Monitor

For high-security entrances where appearance and reliability matter, the Locknetics GF3000 electromagnetic lock delivers heavy-duty protection with discreet installation. This mortise-mounted, fully concealed shear lock provides a certified 3000 lb holding force to secure perimeter and interior doors against forced entry while maintaining a clean, tamper-resistant finish. Designed for modern access control and surveillance systems, the GF3000 includes a Door Status Monitor (DSM) and supports an optional Magnetic Bond Sensor (MBS) so security teams can monitor secure/not-secure and open/closed conditions in real time.

Installation is simplified by automatic voltage selection (12/24 VDC) and microprocessor-controlled features, including an adjustable relock timer (0–30 seconds) for tailored response behavior. The low-temperature rating and limited lifetime warranty on the coil assembly lower long-term maintenance risk, making the GF3000 a dependable choice for commercial, institutional, and critical infrastructure projects. Ideal for secure access control, monitoring, and alarm integration—spec your Locknetics GF3000 shear lock for the next secure-door installation or contact our sales team to integrate it into your security system.
