Gretsch-Unitas Limited, a leading supplier of window and door technology, has announced the launch of the GU Secury LogIQ Automatic Multipoint Lock. By rethinking the locking mechanism, Gretsch-Unitas has created a solution that overcomes the installation and compatibility hurdles often found in automatic hardware, allowing for seamless integration into standard door preparations.
At the core of the GU Secury LogIQ is an innovative trigger mechanism integrated directly within the top and bottom latch bolts. This design allows the lock to engage automatically as soon as the door is closed, achieving a full 20mm bolt projection without the need for external triggers or magnets. To ensure smooth operation for the end user, the system features an integral patented hold-back feature that allows for controlled movement during both daily use and the initial installation process.
The system is designed to fit standard door preparations, allowing fabricators to add automatic locking to their existing product range without the need for new tooling or bespoke routing. With a 45mm backset and universal handing, the GU Secury LogIQ simplifies the retrofitting process for existing configurations, effectively reducing the requirement for specialised stock. This mechanical reliability is supported by rigorous durability testing, with the mechanism exceeding the requirements of BS 6375-2 Class 5 by completing over 100,000 cycles.
GU Secury LogIQ is also backed by the technical validation required for complex commercial and residential specifications. The system has successfully undergone EN 1634-1 fire testing for both 30 minute and 60 minute timber doorsets. This testing programme was specifically designed to reflect real-world requirements for access controlled fire doors.
The fire-tested configurations included the full electronic ecosystem, including the Secury A- Opener motor and connection cables. These were tested alongside both the GU SECUREconnect wireless power transfer system and conventional frame-side cable loops.
By testing the lock, motor, and power transfer components as a single configured system in conjunction with bespoke Norseal intumescent kits, GU provides specifiers with the verified evidence needed to maintain doorset integrity in fire-rated applications.
The GU Secury LogIQ has been included in successful PAS 24:2022 security door assembly tests and holds Secured by Design accreditation. This combination of mechanical innovation and formal certification meets the growing demand for motorised hardware that does not compromise on safety or security documentation.
With UK stock currently available, the system is ready for immediate distribution. The technical team at GU is able to provide guidance on incorporating these verified solutions into upcoming project specifications.
