Securitron GL1-FL Electromechanical Gate Lock, 12/24VDC, Standard Fail Locked

The Securitron GL1-FL is a fail-secure electromechanical gate lock designed for indoor and outdoor pedestrian, vehicle, and security gates. Delivering 2,000 lbs of holding force and reliable operation under up to 100 lbs of gate preload, it provides electronically controlled access for swinging and sliding gates. The lock features automatic 12/24VDC voltage selection, a self-aligning receiver with 1/2-inch horizontal adjustment, and a tamper-resistant cast housing. Its fail-locked design remains secured during power loss and supports an optional mortise cylinder with Adams Rite MS cam for mechanical key override.

Securitron GL1-FL 2,000 lb Fail-Secure Electromechanical Gate Lock

The Securitron GL1-FL Electromechanical Gate Lock is a heavy-duty electronic locking device engineered for pedestrian gates, vehicle access gates, security fences, and controlled outdoor entrances. Manufactured by Securitron, an ASSA ABLOY brand, the GL1-FL provides 2,000 pounds (907 kg) of holding force through an electromechanical locking mechanism designed to maintain secure gate engagement. The fail-secure, or fail-locked, configuration keeps the locking mechanism engaged when electrical power is removed, helping maintain perimeter security during outages. Unlike conventional electromagnetic locks that require continuous power to remain secured, the GL1-FL uses an electromechanical locking design suited to installations requiring security during power interruptions. Its weather-resistant construction supports electrically or manually operated swinging and sliding gates, stock cages, and other commercial access-controlled enclosures.

The GL1-FL incorporates automatic dual-voltage sensing for 12VDC or 24VDC operation, eliminating the need for manual voltage selection during installation. At 12VDC, the manufacturer specifies an initial current draw of 870mA for approximately one second, followed by a reduced current draw of 290mA. At 24VDC, the lock draws approximately 720mA initially and 170mA during reduced-current operation. Rated power consumption is approximately 3.5 watts at 12VDC and 4.1 watts at 24VDC. The locking mechanism is designed to release under up to 100 lbs of preload, accommodating gate pressure caused by wind, mechanical loading, or minor misalignment. A self-aligning receiver with 1/2-inch (12.7 mm) horizontal tolerance helps maintain proper engagement as gate positioning changes through normal operation or gradual sagging.

Designed for electronic gate access control and perimeter security integration, the Securitron GL1-FL can be connected to compatible access control panels, card readers, keypads, remote release switches, and gate operator control systems. An authorized release command electrically disengages the locking mechanism, permitting gate movement while the system provides the appropriate release signal. When power is removed, the fail-locked mechanism remains secured, supporting installations where maintaining a locked perimeter is required. The GL1-FL also accommodates a separately purchased standard mortise cylinder equipped with an Adams Rite MS cam for manual key override. The cylinder can be configured for right-hand or left-hand access according to the installation requirements. Optional Securitron FMK-SW and FMK-SL Flex-Mount bracket kits support swinging and sliding gate applications, allowing the locking assembly to be mounted to suitable gate structures. The standard GL1-FL does not include integrated latch status monitoring; that feature requires the separately specified monitored configuration.

The Securitron GL1-FL features a tamper-resistant cast housing suitable for indoor and outdoor gate installations. The lock assembly measures approximately 7-1/4 inches high, 2-3/4 inches long, and 3-1/4 inches deep, with the manufacturer's dimensional drawing providing additional receiver and installation measurements. It operates across a temperature range of -58 F to 167 F (-50 C to 75 C), accommodating challenging environmental conditions in approved installations. The GL1 Series is documented as UL 294 listed for access control system applications, with additional manufacturer references to CAN/ULC-S533 and applicable NFPA 101 requirements. Installation requires appropriate gate alignment, a regulated DC power supply, compatible control wiring, and a code-compliant means of egress where the gate serves an occupied area. Securitron currently identifies the GL1 gate lock family under its SecuriCare three-year no-fault replacement warranty, subject to the manufacturer's published warranty terms. With its high holding force, preload-resistant release mechanism, dual-voltage operation, and optional mechanical key override, the GL1-FL provides a versatile locking solution for commercial gate security and controlled access applications.
