EDGE EVO is the next evolution in access control hardware solutions. A true IP solution that meets the demands of open architecture,
IP-centric environments, EDGE EVO provides fully distributed intelligence and decision making right to the door, leveraging the IT
infrastructure to the maximum extent possible. Wire the EDGE EVO device to Hi-O interface modules providing connectivity to electronic
door components and access control readers.
Hi-O involves devices with built-in intelligence and a CANbus that links all the devices together. Password protect or encrypt Hi-O CANbus
data trafc. Each Hi-O device (such as the push plate, electric strike, card reader and door operator) is connected to the CANbus by a
single, four-wire cable. Two of the wires supply power and the other two are used for data communication.
For the door peripherals identied in “Step 1 - Identify System Components” on page 2, consult the vendor data
sheets to determine the operational current draw. Typical operational current draw is provided below.
Note: See individual peripheral data sheets for actual operational current draw.

B - Match I/O Requirements to the Hi-O Interface Device
For the door peripherals identied in “Step 1 - Identify System Components” on page 2, the system requires
connection to a Hi-O interface device. In this example, the EDGE EVO Hi-O Edge Door Module (EDM-M) provides
general purpose I/O connectivity.
The Hi-O iCLASS reader does not require connection to the EDM-M and derives power and data connectivity from the
Hi-O CANbus directly.

The combined current requirement for the four door peripherals identied in “Step 1 - Identify System Components” on
page 2 is 413mA @ +12VDC,
or 273mA @ +24VDC.
The EDM-M provides sufcient power when the door peripherals are connected to the Strike/AUX relays congured for
unregulated output at +12VDC/+24VDC. Alternatively, connect the door peripherals to the Strike/AUX relays congured
for Dry contact.
The Hi-O iCLASS reader does not require connection to the EDM-M and derives power and data connectivity from the
Hi-O CANbus directly.
Calculate the total current draw for all door peripherals, all Hi-O interface devices, and all Hi-O enabled readers with
the following equation, adding terms as required.

Compare the required current draw (I

In this example, the EH400 provides sufcient power when operating with +12/+24VDC auxiliary power supplies.
Directly connect the door peripherals identied in “Step 1 - Identify System Components” on page 2 to the I/O ports
of the EDGE EVO Hi-O Edge Door Module (EDM-M). Consult the EDM-M datasheet to determine the available current
capacity for the selected input power scheme of the EH400.
Ensure all door peripherals connected to the Strike/AUX relays and the Reader DC PWR Output or both do not exceed
1.2 Amps (AUX Input) or 400mA (PoE Input) combined. Alternatively, connect the door peripherals to the Strike/AUX
relays congured for Dry contact up to 2 Amps per relay.
