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.

Network: static IP address: 192.168.0.251
Subnet Mask: 255.255.0.0
Default Gateway: 192.168.0.1
DNS Server: 192.168.0.1
Primary Host port: IP server, no encryption, port 3001, communication address: 0
Alternate Host Port 1: RS-232, 38,400 baud, no encryption, no flow control.
4. Bulk Erase Configuration Memory:
The bulk erase function can be used for the following purposes:
Erase all configuration and cardholder database (sanitize board)
Update OEM default parameters after OEM code has been changed
Recover from database corruption causing EP1502 board to continuously reboot
If clearing the memory does not correct the initialization problem, contact technical support.
Bulk Erase Steps: Do not remove power during steps 1-8.
1. Set S1 DIP switches to: 1 & 2 "ON", 3 & 4 "OFF".
2. Apply power to the EP1502 board.
3. Watch for LEDs 1 & 2 and 3 & 4 to alternately flash at a 0.5 second rate.
4. Within 10 seconds of powering up, change switches 1 or 2 to "OFF". If these switches are not
changed, the EP1502 board will power up using the OEM default communication parameters.
5. LED 2 will flash indicating that the configuration memory is being erased.
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).
5. Input Power, Cabinet Tamper and UPS Fault Input Wiring:
The EP1502 requires 12 to 24 Vdc power. Locate power source as close
to the unit as possible. Connect power with minimum of 18 AWG wire.
Connect the GND signal to earth ground in ONE LOCATION within the
system! Multiple earth ground connections may cause ground loop
problems and is not advised.
Observe POLARITY on 12 to 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.

6. 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 drain wire and shield for communication.
IMPORTANT NOTE! Install the termination jumper ONLY on the panel at each end of the RS-485
bus. Failure to do so will compromise the proper operation of the communication channel!
7. Reader Wiring:
Each reader port supports a reader with TTL (D1/D0, Clock/Data), F/2F, or 2-wire RS-485 signaling. Power
to the readers is selectable: 12 Vdc (VIN must be greater than 20 Vdc), or power is passed-through (PASS)
from the input voltage of the EP1502 (TB1-VIN), 180 mA maximum per reader port. Readers that require
different voltage or have high current requirements must be powered separately. Refer to the reader
manufacture specifications for cabling requirements. In the 2-wire LED mode the buzzer output is used to
drive the second LED. Reader port configuration is set via the host software.
To fully utilize each reader port:
TTL signaling requires a 6-conductor cable (18 AWG)
F/2F signaling requires a 4-conductor cable
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.

8. Input Circuit Wiring:
Typically, these inputs are used to monitor door position, request to exit, or alarm contacts. Input circuits
can be configured as unsupervised or supervised. When unsupervised, reporting consists of only the open
or closed states. When configured as supervised, the input circuit will report not only open and closed, but
also open circuit, shorted, grounded*, and foreign voltage*. A supervised input circuit requires two resistors
be added to the circuit to facilitate proper reporting. The standard supervised circuit requires 1k ohm, 1%
resistors and should be located as close to the sensor as possible. Custom end of line (EOL) resistances
may be configured via the host software.
* Grounded and foreign voltage states are not a requirement of UL 294 and therefore not verified by UL

9. Relay Circuit Wiring:
Four relays with Form-C contacts are provided for controlling door lock mechanisms or alarm signaling.
The relay contacts are rated at 5 A @ 30 Vdc, dry contact configuration. Each relay has a Common pole
(C), a Normally Open pole (NO) and a Normally Closed pole (NC). When you are controlling the delivery
of power to the door strike, the Normally Open and Common poles are used. When momentarily removing
power to unlock the door, as with a mag lock, the Normally Closed and Common poles are used. Check
with local building codes for proper egress door installation.
Door lock mechanisms can generate feedback to the relay circuit that can cause damage and premature
failure of the relay. For this reason, it is recommended that a diode be used to protect the relay. Wire
should be of sufficient gauge to avoid voltage loss.
10.Memory and Real Time Clock Backup Battery:
The static RAM and the real time clock are backed up by a lithium battery when input power is removed.
This battery should be replaced annually. If data in the static RAM is determined to be corrupt after power
up, all data, including flash memory, is considered invalid and is erased All configuration data must be re-
downloaded. Remove the insulator from the battery holder after installation. Battery type: BR2325,
BR2330, or CR2330.
11.IT Security
When installing the EP1502, it is important to ensure that it done in a secure manner.
Upon installation, the user accounts to the web configuration page should be created with secure
passwords, and that all DIP switches are in the off position for the normal operating mode. The EP1502
is shipped from the factory with a default login account, which is enabled when DIP 1 is moved from OFF
to ON. The default login user name and password will be available for five minutes once enabled.
Therefore, it is important that at least one user account is defined, and the DIP switches are set to OFF
before the EP1502 is commissioned. It is also highly recommended not to configure the EP1502 with an
IP address that is accessible from the public Internet.
To further enhance network security, options are available to disable SNMP, Zeroconf discovery, as well
as the web configuration module itself. Additionally, data encryption can also be enabled over the host
communication port.
12.Status LEDs:
Power-up: All LED's OFF.
Initialization: LED's 1, 2, 3, TMP, FLT, R1, R2, IN1, IN2, IN3, IN4, IN5, IN6, IN7 and IN8 are sequenced
during initialization. LED's 1, 3, and TMP are turned ON for approximately 4 seconds after the hardware
initialization has completed, then the application code is initialized. The amount of time the application
takes to initialize depends on the size of the database, about 3 seconds without a card database. Each
10,000 cards will add about 3 seconds to the application initialization. When LED's 1, 2, 3 and TMP flash
at the same time, data is being read from or written to flash memory, do not cycle power when in this
state.
Diode Selection:
Diode current rating: 1x strike current
Diode breakdown voltage: 4x strike voltage
For 12 Vdc or 24 Vdc strike, diode 1N4002
(100V/1A) typical.

Mercury Security © 2015 EP1502 DOC 10107-0031 REV 1.06 Page 7
Running: After initialization is complete, the LEDs have the following meanings: At power up, LEDs 2
through 6 are turned ON then OFF in sequence.
