Usage Features:

Flexible Power Options: The AC12 supports various power configurations, including PoE++, PoE+, PoE, and DC Only, with different power outputs for readers, wet locks, USB, and DC power out. This flexibility allows the controller to adapt to diverse installation requirements and power availability. For instance, with PoE++, it can power a single reader and disable USB, or support an in/out door configuration with USB enabled.

Reader Compatibility: The device is designed to work with both Verkada RS-485 readers and standard Wiegand readers. This broad compatibility ensures seamless integration with a wide range of access control peripherals.

Door Lock Configurations: The AC12 supports both fail-secure and fail-safe locking hardware. In a fail-secure configuration, the lock remains locked when power is interrupted, typically used for Normally Open (NO) configurations. In a fail-safe configuration, the lock unlocks when power is interrupted, typically used for Normally Closed (NC) configurations. The voltage selection switch (12VDC/24VDC) allows for proper power delivery to the locking hardware.

Input Connectivity: The controller includes inputs for Door Position Indicators (DPI) and Request-to-Exit (REX) sensors. DPIs are typically configured as Normally Closed (NC) to detect when a door is open or closed, while REX inputs are Normally Open (NO) to trigger door unlocks. These inputs are crucial for comprehensive door monitoring and control.

AUX Inputs: The AC12 features one AUX input, which is normally open by default but can be changed to normally closed in Verkada Command. These inputs can connect to devices like intercoms and panic buttons, with all associated events logged in Command. AUX inputs can also be programmed to configure a connected device to initiate a lockdown or unlock a door.

Easy Registration and Setup: The device can be easily registered and set up by scanning a QR code on the product using a smartphone or laptop, or by manually registering via verkada.com/start. This streamlines the deployment process.

LED Behavior for Status Monitoring: The AC12 provides clear LED indicators for Status, Network, and PoE Out, offering quick visual diagnostics:

Status LED:
- Solid Blue: Running and healthy.
- Flashing Blue: Network issue (diagnosed via Network LED).
- Solid Orange: Booting up.
- Flashing Orange: Updating firmware.
- Solid Magenta: Power input is 802.3af PoE, limiting some functionality (refer to page 5 of the install guide for details).
- Flashing Magenta: Unknown issue (contact support).
Network LED: Flashes in a specific order (1 blue flash followed by orange flashes) to indicate various error states, such as inability to connect to the switch, no IP address, unreachable gateway, duplicate IP addresses, inability to resolve hostnames, no NTP server response, SSL connection issues, or unreachable Verkada endpoints.
PoE Out LED:
- Solid Blue: Data and power up to 30W.
- Solid Green: Data and power up to 27W.
- Magenta: Data only.
- No Light: PoE Out disabled via Command.
- Blinking Amber: Data only.

Maintenance Features:

Recommended Testing: To ensure ongoing functionality, Verkada recommends checking the AC12's interfaces every 6 months. This includes:

Input Testing: Short each input to its adjacent GND port and verify that the corresponding LED illuminates.
Relay Output Testing: Use a multimeter to confirm expected impedance across relay outputs (closed across NC and COM, open across NO and COM).
Voltage Verification: Use a multimeter to verify correct voltage at the 12V AUX output, relay contact outputs, and reader power outputs.
Grounding Check: Check the shielding cables of the readers and other AUX wiring for proper connection to the grounding screw(s) on the chassis.

Professional Installation and Maintenance: Installation and/or maintenance of the AC12 must be performed by trained professionals only, ensuring proper setup and adherence to safety standards.

Wiring Requirements: The manual provides detailed recommended wiring specifications for various components (readers, power, REX, door contact) including AWG, twisted pair, conductor, shielding, and maximum length. It emphasizes the importance of using shielded wiring and proper grounding to prevent interference and ensure product behavior. Specifically, it advises connecting the drain wire (bare metal) from the reader cable bundle to the drain wire in the shielded cabling, and then connecting the drain wire at the other end of the shielded cabling to the AC12 drain wire screw. Improper grounding and shielding may result in unintended product behavior.

Network Settings: The AC12 requires an Ethernet connection with DHCP. Users need to configure firewall settings to communicate with the AC12, ensuring TCP port 443, UDP port 123 (NTP time synchronization), and MAC address presence for single port in passthrough mode are open.

Security Screw Access: To maintain unobstructed access to the captive security screw on the controller's cover, a minimum of 6 inches (152mm) of clearance from the bottom edge of the device is required when mounting. This allows for easy access during maintenance or troubleshooting.

Detachable Terminal Blocks: The terminal blocks can be detached from the device, simplifying wiring during installation and maintenance.

Firmware Updates: The AC12's firmware can be updated, indicated by a flashing orange status LED. This ensures the device stays current with the latest features and security enhancements.
