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 physical barriers.
The EP1502 communicates with the host via on-board 10-BaseT/100Base-TX Ethernet port. Alternatively,
port 1 (RS-232) can be used for host communication.
Each reader port can accommodate a reader that utilizes TTL (D1/D0, Clock/Data), F/2F, or 2-wire
RS-485 device signaling, and also provides tri-state 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 that may be used for monitoring
the door contacts, exit push buttons and alarm contacts. Input circuits may be configured as unsupervised
or supervised. The EP1502 requires 12 to 24 Vdc for power.
