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 read­head 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.

3. EP1502 Wiring and Setup:

Jumpers:

The EP1502 processor hardware interface is configured using jumpers to setup the port interface and end
of line termination.

Note 1: The input power (VIN) must be 20 Vdc minimum if the 12 Vdc selection is to be used.

Note 2: Observe POLARITY connection to LED. External current limiting is not required.

DIP Switches:

The four switches on S1 DIP switch configure the operating mode of the EP1502 processor.
DIP switches are read on power-up except where noted. Pressing switch S2 causes the EP1502 to reset.

All other switch settings for unassigned and are reserved for future use. X = don’t care.

In the factory or OEM default modes, downloaded configuration/database is not saved to flash memory.

Factory Default Communication Parameters:

Network: static IP address: 192.168.0.251
Communication address: 0
Primary Host port: IP server, no encryption, port 3001.
Alternate Host Port 1: RS-232, 38,400 baud, no encryption, no flow control.

Bulk Erase Configuration Memory:

The bulk erase function can be used for the following purposes:

 To erase all configuration and cardholder database data.
 To recover from a corrupted database in the unlikely event the database gets corrupted and causes

the EP1502 to continuously reboot.
When power is applied with S1 switches set to 1 & 2 ON and 3 & 4 OFF, there is a 10-second window
that if switch 1 or 2 is changed to the OFF position memory is erased. The LEDs flash the following
pattern when in the reset window: LED 1 & 2 and LED 3 & 4 flash alternately at .5 second rate. When
erasing memory, LED 2 flashes at a 2 second rate;
seconds to erase the memory. LEDs 1 and 4 flash for 10 seconds after the memory has been erased,
then the EP1502 will re-boot.

DO NOT CYCLE POWER

. It takes less than 60

4. Input Power, Cabinet Tamper and UPS Fault Input Wiring:

The EP1502 requires 12-24 Vdc power. Locate power source as
close to the unit as possible. Connect power with minimum of 18
AWG wire.

LOCATION within the system! Multiple earth ground connections
may cause ground loop problems and is not advised.

Observe POLARITY on 12-24 Vdc input!

There are two dedicated inputs for cabinet tamper and UPS fault
monitoring. Normal (safe) condition is a closed contact. If these
inputs are not used, install a jumper wire.

Connect the GND signal to earth ground in ONE

5. Communication Wiring:

The EP1502 controller communicates to the host via the on-board 10-BaseT/100Base-TX Ethernet
interface (port 0) and/or RS-232 interface (port 1). RS-232 interface is for direct one to one connection to
a host computer port or via modem, 25 feet maximum.

The serial I/O device communication port (TB3) is a 2-wire RS-485 interface which can be used to
connect additional I/O panels. The interface allows multi-drop communication on a single bus of up to
4,000 feet (1,219 m). Use twisted pairs (minimum 24 AWG) with an overall shield for communication.
