1. General:
The eMAX-LP4502 is an IP Network-based Intelligent Area Controller that provides local transaction
processing & decision making, transaction/event reporting, and local database storage for the eMAX
hardware platform and the Maxxess eAXxess and eFusion Access Control Systems. The eMAX-
LP4502 provides two (2) Card Reader interfaces for the control of two physical barriers.
The eMAX-LP4502 Host communication is via the on-board 10-BaseT/100Base-TX Ethernet port, or
the Micro USB port (2.0) with an optional Micro USB to Ethernet adapter.
Each Reader Port of the eMAX-LP4502 can accommodate a reader that utilizes TTL/Wiegand
(D1/D0), TTL/Magnetic Stripe (Clock/Data), F/2F Protocol (standard or supervised), or 2-wire RS-
485 device signaling such as OSDP, and also provides tri-state LED control, and buzzer control (one
wire LED mode only). Each Reader Port, if configured for 2-wire RS-485 OSDP Readers, can
support two (2) multi-dropped Readers in an IN/OUT Reader configuration, resulting in the support
for up to four (4) Readers.
The eMAX-LP4502 provides four (4) Form-C Contact relay outputs which may be used for door
strike control or alarm signaling. The relay contacts are rated at 5A @ 30Vdc resistive on the
Normally-Open (N/O) contacts, and 3A @ 30Vdc resistive on the Normally-Closed (N/C) contacts,
dry contact configuration. Eight (8) 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 eMAX-LP4502 requires 12 to 24 Vdc for power.

(Refer to online HELP in the Maxxess host software for important details on encryption)
NOTE: See Appendix A for details on configuring the eMAX-LP controller’s IP address
4. Bulk Erase Configuration Memory:
The Bulk Erase Function can be used for the following purposes:
➢Erase all configuration and cardholder database (sanitize board, less 3rd-Party Applications)
➢Update OEM default parameters after OEM code has been changed
➢Recover from database corruption causing eMAX-LP4502 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 eMAX-LP4502 board. LED 1 on for up to 15 seconds while board boots up.
3. After the eMAX-LP4502 boots up, watch for LEDs 1 & 2 and 3 & 4 to alternately flash at a 0.5
second rate.
4. Within 10 seconds after the above pattern starts, change switches 1 or 2 to "OFF". If these
switches are not changed, the eMAX-LP4502 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, usually a lot less.
7. When complete, only LEDs 1 & 4 will flash for about 3 seconds.
8. The eMAX-LP4502 will complete its initialization in 2 seconds after LEDs 1 & 4 stop flashing.

February, 2019 eMAX-LP4502-Man Page 8 of 20
5. Input Power, Cabinet Tamper, and UPS Fault Wiring:
The eMAX-LP4502 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.
Be sure to 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 eMAX-LP4502 controller communicates to the host via the on-board Ethernet 10-
BaseT/100Base-TX port, and/or the USB port (2.0) with an optional USB to Ethernet adapter.
The Serial I/O device communication ports, TB2 for port 1 and TB3 for port 2, are 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 1-twisted pair, shielded cable, 120
ohm impedance, 24 AWG, 4,000 ft. (1,219 m) maximum 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 of the eMAX-LP4502 supports a reader with TTL/Wiegand (D1/D0), TTL/Magnetic
Stripe (Clock/Data), F/2F (standard or supervised) or 2-wire RS-485 OSDP 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 LP4502 (TB1-VIN), 300 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. Do
not terminate any RS-485 devices connected to a reader port.
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 Twisted Pair, with drain wire and shield).

8. Input Circuit Wiring:
The eMAX-LP4502 provided 8 inputs that are typically 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 circuit, 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.
NOTE: Grounded and foreign voltage states are not a requirement of UL 294 and therefore not
verified by UL.

9. Relay Circuit Wiring:
The eMAX-LP4502 includes four (4) relays with Form-C contacts (dry) that provide for controlling
door lock mechanisms or alarm signaling. Each relay has a Common pole (C), a Normally Open pole
(NO) and a Normally Closed pole (NC), and is rated at 5A @ 30Vdc resistive on the Normally-Open
(N/O) contacts, and 3A @ 30Vdc resistive on the Normally-Closed (N/C) contacts. When controlling
the delivery of power to the door strike, the Normally Open and Common poles are typically used.
When momentarily removing power to unlock the door, as with a mag lock, the Normally Closed and
Common poles are typically 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 plus affect the operation of the eMAX-LP4502. 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.
DIODE SELECTION:
DIODE Current Rating > 1 X STRIKE CURRENT
DIODE Break Down Voltage: 4X STRIKE VOLTAGE
FOR 12VDC or 24VDC STRIKE, DIODE 1N4002
(100V /1A) TYPICAL
10. Memory 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: BR2330 or CR2330.
11. IT Security
When installing the eMAX-LP4502, it is important to ensure that it is 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
eMAX-LP4502 is shipped from the factory with a default login account, which is enabled when DIP
Switch 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 eMAX-LP4502 is commissioned. It is also highly
recommended not to configure the eMAX-LP4502 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: After power is applied or reset switch pushed, LED 1 is ON for about 15 seconds, then
LED’s 2, 3, 4, 5, 6, R1, R2, IN1, IN2, IN3, IN4, IN5, IN6, IN7 and IN8 are flashed once at the beginning
of initialization. LEDs 3 and 4 is turned ON for approximately 1 second 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 1 second without a card database. Each 10,000
cards will add about 2 seconds to the application initialization. When LED's 1, 2, 3 and 4 flash at the
same time, data is being read from or written to flash memory, do not cycle power when in this state.
If the sequence stops or repeats, perform the bulk erase procedure, see section 4.
Running: After initialization is complete, the LEDs have the following meanings:
