EP1502 Intelligent Controller
with Two Reader Interface
Installation and Specifications:
1. General
The EP1502 intelligent controller provides decision making, event reporting, and database storage for the
Mercury hardware platform. Two reader interfaces provide control for two doors.
It communicates with the host via on-board 10-BaseT/100Base-TX Ethernet port. Alternatively, port 1
(RS-232) can be used for host communication.
Two physical barriers can be controlled with the EP1502. Each reader port can accommodate a read-
head that utilizes Wiegand, magnetic stripe, or 2-wire RS-485 electrical signaling standards, one or two
wire LED controls, 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 EP1502 requires 12-24 Vdc for power. It is recommended that the EP1502 be mounted
.25" minimum above any conductive surface.
