Securitron GL1-FSM Electromechanical Gate Lock, 12/24VDC, Monitored Fail Safe

The Securitron GL1-FSM is a heavy-duty, fail-safe monitored electromechanical gate lock providing 2,000 lbs of holding force for indoor and outdoor access control applications. Operating on automatically selected 12/24 VDC power, the GL1-FSM accommodates up to 100 lbs of gate preload and features an integrated latch status monitoring option. Its weather-resistant, tamper-resistant housing and self-aligning receiver support reliable locking for swinging and sliding pedestrian, vehicle, and livestock gates.

Securitron GL1-FSM 2,000 lb Fail-Safe Monitored Electromechanical Gate Lock

The Securitron GL1-FSM electromechanical gate lock provides 2,000 lbs (907 kg) of holding force for securing swinging and sliding gates in commercial, industrial, and controlled-access environments. Designed for both electrically operated and manually operated gates, this fail-safe monitored configuration releases its locking mechanism when electrical power is removed and incorporates latch status monitoring for integration with compatible security systems. The GL1-FSM accommodates up to 100 lbs of preload, allowing the lock to release under gate pressure caused by wind, gate movement, or mechanical loading. Its weather-resistant construction supports indoor and outdoor applications, including pedestrian entrances, vehicle access gates, and agricultural enclosures.

The GL1-FSM features automatic 12/24 VDC voltage detection, eliminating manual voltage selection during installation. At 12 VDC, the lock draws approximately 870 mA during its initial one-second activation period before reducing to 290 mA, with power consumption of 3.5 watts. At 24 VDC, initial current reaches 720 mA before decreasing to 170 mA, with power consumption of 4.1 watts. The lock measures 2-3/4 inches long, 7-1/4 inches wide, and 3-1/4 inches deep and incorporates a tamper-resistant cast housing. Its operating temperature range extends from -58 F to 167 F (-50 C to 75 C), supporting installations exposed to demanding outdoor conditions.

The GL1-FSM surface-mounted gate lock includes a self-aligning receiver that accommodates up to 1/2 inch (12.7 mm) of horizontal gate misalignment, helping compensate for gate sag and movement during operation. The monitored configuration provides latch status feedback for compatible access control panels and security monitoring equipment. Installation flexibility includes compatibility with the separately available Securitron FMK-SL Flex-Mount Bracket Kit for sliding gates and FMK-SW Flex-Mount Bracket Kit for swinging gates. These mounting options support gate installations where standard hardware positioning is restricted by frame geometry or gate construction.

The Securitron GL1-FSM is UL 294 listed for access control applications and combines fail-safe operation, monitored latch status, and preload-resistant locking in one electromechanical gate security device. Its black housing and compact surface-mounted configuration support installations where exposed locking equipment must withstand repeated gate operation and environmental exposure. The GL1 series is covered by the Securitron SecuriCare three-year, no-fault, no-questions-asked warranty, according to current manufacturer documentation. Installers must verify compatible power supplies, mounting hardware, gate alignment, and applicable emergency egress requirements before installation.
