Securitron GL1 Electromechanical Gate Lock

High-Security Electromechanical Lock for Swing and Slide Gates

The GL1 Electromechanical Gate Lock is a rugged, high-security solution designed for swing and slide gates in commercial, industrial, and restricted-access environments. Engineered for performance under pressure, it delivers 2,000 lbs of holding force and operates under up to 100 lbs of preload - making it ideal for gates that sag, misalign, or experience pressure from wind or manual force.

Built for perimeter applications, the GL1 supports dual voltage (12/24 VDC) and can be installed on manual or automated gate systems. Its weather-resistant cast housing, surface-mount design, and compatibility with mortise cylinders make it adaptable for various high-risk sites. Optional status monitoring contacts allow system-level lock verification when integrated with access control panels.

Key Features

• 2,000 lbs of holding force for reliable gate retention
• Operates under preload conditions up to 100 lbs
• Auto-sensing dual voltage (12/24 VDC) - no manual adjustment required
• Tamper-resistant cast aluminum housing for rugged durability
• Surface-mount design simplifies installation on swing or slide gates
• Self-aligning receiver (+/– ½") compensates for gate sag or misalignment
• Optional status monitoring output for lock state feedback
• Compatible with key cylinder for mechanical override
• Built to operate in harsh outdoor conditions year-round

Models & Variants

GL1-FS (Fail-Safe):

• Unlocks automatically when power is lost.
• Recommended for gates requiring emergency egress or compliance with safety codes. 
• Requires continuous power to remain locked.

GL1-FL (Fail-Locked/ Fail-Secure):

• Stays locked during a power failure.
• Used in solar-powered or off-grid gate systems where maintaining continuous power is not advisable. Requires power only during the unlock cycle, making it energy efficient.
• Recommended for high security sits where maintaining a locked gate during outages is critical. 

GL1-FS-M (Fail-Safe with Monitoring):

• Includes all the features of the GL1-FS model.
• Built-in status contact to confirm if the bolt is engaged.
• Requires integration with commercial access control or alarm systems.

GL1-FL-M (Fail-Locked with Monitoring): 

• Includes all the features of the GL1-FL model.
• Built-in status contact to confirm if the bolt is engaged.
  
• Requires an access control system.

The GL1 is available in four factory configurations to meet different power, safety, and integration needs. All models accept a mortise cylinder (sold separately) for manual key override, allowing physical access during power or system failures.

Available Accessories:

• Power supply
• Mortise lock
• Mounting Bracket for swing gates
• Mounting Bracket for slide gates

Conclusion

The GL1 Electromechanical Gate Lock is built for secure, continuous-duty use in perimeter-critical installations. Whether applied to a high-traffic swing gate or a solar-powered slide gate, it offers fail-safe and fail-secure options, access control integration, and tamper-resistant durability. For property managers, security integrators, and system designers, the GL1 delivers proven reliability where gate security cannot be compromised.
