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.

- Page 1 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.
- Page 2 TB7-1 Input 8 TB7-2 TB7-3 Input 7 TB7-4 Jumpers: The EP1502 processor hardware interface is configured using jumpers to setup the port interface and end of line termination. JUMPERS SET AT DESCRIPTION Factory Use Only 10-Base-T/100Base-Tx Ethernet Connection (Port 0)
- Page 3 6. Full memory erase takes up to 60 seconds. 7. When complete, only LEDs 1 & 4 will flash for 8 seconds. 8. The EP1502 board will reboot 8 seconds after LEDs 1 & 4 stop flashing (no LEDs are on during this time).
- Page 4 RS-485 signaling requires two 2-conductor cables. Use one cable for power (18 AWG) and one cable for communication (24 AWG, with drain wire and shield) J7 – Reader Power Select If the input voltage to the EP1502 is 12 Vdc, jumper J7 MUST be in the PASS position.
