An access controller is a professional element for the protection of perimeters and gates. They are located in safe and hidden places, allowing the connection of the readers, which are placed in the visible place of the installation and identify the user who wants to access, as well as the connection to the electronic locks, which will be activated if the user is allowed access.
This controller supports readers based on the Wiegand protocol, which allows the connection through direct wiring of each reader to the controller. It has 2 readers to perform entry and exit at each door and supports readers that connect through RS485 and allow connection through BUS (cascading), allowing up to 2 readers by this method.
This model has 2 relay outputs, being configurable as dry contact (without voltage) or wet contact (with voltage).
By using an access controller, it is possible to ensure certain functions, such as opening all doors when a fire signal is received or triggering an alarm when a forced door is detected. Thanks to its inputs and outputs, it is possible to manage these functions in a simpler way.
Advanced configurable functions: anti-pass-back technology (does not allow a person to pass through if he/she is already inside), locks (double door system that allows the passage of people one at a time) or capacity control (does not allow access to more users once a certain number has been exceeded).
The Alta Access software is used to configure users, schedules and access groups, as well as special functions, relay opening times or reader reading times.
