eMAX-EP4502 INTELLIGENT CONTROLLER
1. General:
The eMAX-EP4502 intelligent controller provides decision making, event reporting, and database storage for
the Mercury hardware platform. Two reader interfaces provide control for two doors.
The eMAX-EP4502 communicates with the host via on-board 10Base T/100Base-TX Ethernet port.
Two doors / physical barriers can be controlled with the eMAX-EP4502. Each reader port can accommodate a
read-head that utilizes Wiegand, magnetic stripe, or 2-wire RS-485 electrical signaling standards, and also
provides tri-stated LED control, and buzzer control (one wire LED mode only). Four (4) Form-C relay outputs
may be used for strike control or alarm signaling. The relay contacts are rated at 5 A @ 30 Vdc, dry contact
configuration. Eight (8) inputs are provided for monitoring the door contacts, exit push buttons and alarm
contacts. The eMAX-EP4502 requires 12 to 24 Vdc for power.
