Hold-open time — how long the door stays fully open after activation clears — is set as a parameter on the control. On ESA I it is typically a potentiometer/parameter adjustment; on ESA II it is a programmable parameter accessed through the program switch / service display. Increase the value for slower foot traffic or accessibility requirements and decrease it for higher-throughput entries. Make the change, then test a full cycle to confirm the door dwells for the expected interval before closing.
