Before starting installation, determine which components will be used in the system and analyze the power requirements to avoid
over-loading the EDGE EVO Hi-O Networked Controller & Reader (EH400-K).
The steps that follow illustrate sizing power requirements for the system.
Step 1 - Identify System Components
Identify the components that will be used in the system. A typical installation may include the following components:
• Door Position Switch – Detects when the door is open or closed.
• Magnetic Lock – Holds the door locked.
• Request to Exit (REX) Switch – Unlocks the door when exiting the secured area.
• EDGE EVO Hi-O Standard Networked Controller (EH400-K) – Provides access control and manages all
peripherals around the door.
• iCLASS Wiegand Reader – Provides entry into the secured area.
Step 2 - Create System Layout
Using the components identified in “Step 1 - Identify System Components” on page 2, create the system layout.
In this example, the EH400-K is connected to the remote server through an Ethernet connection and manages door
peripherals over the Hi-O bus. Controlling downstream door peripherals, the EH400-K is a fully integrated single-door
controller offering discrete I/O and Wiegand/Clock-and-Data interfaces to external readers. The EH400-K receives inputs
from the Door Position Switch and REX Switch to drive the Magnetic Lock output.
