EP4502 Intelligent Controller
with Two Reader Interface
Installation and Specifications:
1. General
The 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 EP4502 communicates with the host via on-board 10Base T/100Base-TX Ethernet port.
Two physical barriers can be controlled with the 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 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 inputs are provided for monitoring the door contacts, exit push buttons and
alarm contacts. The EP4502 requires 12 to 24 Vdc for power.
