ACC1 access switch

The ACC1 access switch is a component used in access control systems to monitor door status and control access, often integrated with door controllers like the ADC-ACC1-17.

Overview

The ACC1 access switch is typically used to detect the open or closed status of a door in an access control system. It can also trigger relocking of the door when it returns to a closed state and help identify if a door has been forced open without proper authorization. This functionality is essential for maintaining security and monitoring entry points in commercial or residential installations .

Wiring and Integration

For systems like the ADC-ACC1-17 door controller, the ACC1 switch connects to one of the onboard inputs, which can also support a Request-to-Exit (REX) device. The switch generally has two wires that are connected to the input terminals on the access control board. Door position switches may be surface-mounted or concealed within the door frame, depending on the installation requirements .

Access Control Cabling

The ACC1 switch often uses composite access control cables, such as the ACC-1 series, which include multiple conductors (e.g., 2C/22 AWG, 4C/22 AWG, 4C/18 AWG, 6C/22 AWG) and are shielded and bundled for reliable signal transmission. These cables are designed to be compatible with a wide range of access control devices and simplify installation by providing multiple conductor options in a single cable .

Additional Notes

• ACC1 switches are sometimes referred to as Accessory 1 or ACC 1 in documentation.
• They are part of a broader access control ecosystem, including door controllers, REX devices, and monitoring systems.
• Proper installation ensures accurate door status reporting and enhances security by preventing unauthorized access. In summary, the ACC1 access switch is a key component in access control systems, providing door status monitoring and integration with controllers via dedicated inputs and compatible composite cabling .
