Directly connect the door peripherals identified in “Step 1 - Identify System Components” on page 2 to the I/O ports
of the EDM-M. Consult the EDM-M datasheet to determine the available current capacity for the selected input power
scheme of the EHR40 / EHRP40.
Ensure all door peripherals connected to the Strike/AUX relays and the Reader DC PWR Output or both do not exceed
1.125 Amps (AUX Input) or 0.35 Amps (PoE Input) combined. Alternatively, connect the door peripherals to the Strike/
AUX relays configured for Dry contact up to 2 Amps per relay.
Step 4 - Select Power Scheme
Select the appropriate power scheme to meet overall current draw. Using the analysis from the previous sections equates to the
following power scheme possibilities.
