Multi-Gate Access Control – 3PL

Some machines in automated warehouses require an access point on every single aisle, meaning a multi-door access system needs to be implemented to allow operators to safely enter the safeguarded space without incurring high installation costs. These access points do not lead into the ASRS system directly and do not need to be EN 528/619 compliant, so Fortress have devised a great solution that is both cheaper to install and extremely safe for operators / maintenance personnel.

The gate can only be opened once the 'Request to Enter' button has been pressed on the Networked Control Unit. When access has been granted the actuator can be removed from the head of the interlock, allowing access to the gate.

The forced extracted safety key ensures personnel take the key with them inside the safeguarded space, preventing unexpected restart.
