Electric Latch Bolt Lock — Durable, Secure, Fast Why you need it Provides a dependable, low-maintenance locking solution for doors where reliable electronic control and physical strength are required. Eliminates frustration from slow or unreliable latches by delivering fast, consistent locking and unlocking. Increases safety and predictable behavior in access-control applications by using a defined fail-safe mode. Key benefits Durable construction: Made from a robust, high-grade aluminum alloy for long-lasting performance and resistance to wear. Predictable fail-safe operation: The lock is fail-safe — it unlocks when power is off and locks when power is on — offering a clear, secure response to power changes. Fast, responsive action: Sensitive mechanism ensures quick engagement and release to minimize delays and user inconvenience. Adjustable timing: Built-in delay options let you choose 0, 3, or 6 seconds delay after activation to match how you use the door; factory default is 0 seconds. Features and performance Function: Electric latch bolt (fall-rigel) design for controlled electronic locking and unlocking. Mechanism: Reliable locking mechanism engineered for stable, repeatable operation. Material: High-quality aluminum alloy body for strength and durability. Timing: Selectable delay of 0 s / 3 s / 6 s; default = 0 s. Ideal for metal doors and heavy-use entrances where a robust mechanical latch combined with electronic control is needed. Practical applications Commercial and industrial entrances: Use on staff entrances, storage rooms, or workshops where a durable, electronically controlled latch is required. Office and multi-tenant buildings: Integrate on interior or exterior metal doors to provide fast access control with predictable fail-safe behavior. Service doors and utility rooms: Provide reliable locking for doors that need both mechanical strength and electronic operation. What it solves Removes uncertainty from lock behavior during power changes by providing fail-safe unlocking. Reduces door hold/open delays with fast actuation and configurable delay options. Replaces weaker latch hardware with a sturdier aluminum-alloy electric latch suited to heavy-use doors, particularly metal doors. Notes Factory delay setting is 0 seconds; changeable to 3 or 6 seconds to suit door usage. Designed as an electric latch bolt lock with fail-safe operation and high-strength construction for reliable, repeatable performance.
