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 (EHR40/EHRP40).
The steps that follow illustrate sizing power requirements for the system.
Step 1 - Identify System Components
Installation components include the following examples.
• 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 Edge Door Module (EDM-M) – Connects peripheral devices to the Hi-O bus.
• EDGE EVO Hi-O Networked Controller & Reader – Provides entry into the protected area and manages all peripherals
around the door.
Step 2 - Create System Layout
Using the components identified in “Step 1 - Identify System Components” on page 2, create the overall system layout.
This example illustrates connecting the EH40/EHRP40 to the remote server through an Ethernet connection and manages
door peripherals over the Hi-O bus. The EDM-M receives inputs from the Door Position Switch and REX Switch to drive the
Magnetic Lock output.
