LP1501 Intelligent Controller
with Paired Reader Interface for One Physical Barrier
Installation and Specifications:
1. General:
The LP1501 intelligent controller provides decision making, event reporting and database storage for the
Mercury hardware platform. Two reader interfaces configured as paired or alternate readers provide
control for one physical barrier.
Host communication is via the on-board 10-BaseT/100Base-TX Ethernet port.
Note: For UL compliance, the Power Sourcing Equipment (PSE) such as a PoE or PoE+ enabled network
switch and/or PoE or PoE+ power injectors must be UL Listed under UL294B.
Reader port 1 can accommodate a reader that utilizes TTL (D1/D0, Clock/Data), F/2F, or 2-wire RS-485
device signaling (for example an OSDP reader), also provides tri-state LED control, and buzzer control
(one wire LED mode only). This port can also utilize multiple 2-wire RS-485 multi-dropped devices, such
as up to two OSDP readers or up to eight remote serial I/O devices.
Reader port 2 can accommodate a reader that utilizes TTL (D1/D0, Clock/Data), or F/2F signaling, also
provides tri-state LED control, and buzzer control (one wire LED mode only). Two Form-C contact relay
outputs may be used for door strike control or alarm signaling. The relay contacts are rated at 2 A @ 30
Vdc, dry contact configuration. Two inputs are provided that may be used for monitoring the door contact,
exit push button or alarm contact. Input circuits can be configured as unsupervised or supervised. The
LP1501 requires Power over Ethernet (PoE or PoE+) or 12 Vdc for power. The LP1501 may be mounted
in a 3-gang switch box; a mounting plate is supplied with the unit, or may be mounted in an enclosure; the
supplied mounting plate has mounting holes that match the MR50 mounting footprint.

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 LP1501 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 LP1501 board. LED 1 on for about 15 seconds while LP1501 boots up.
3. After the LP1501 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 LP1501 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 LP1501 board will complete its initialization in 2 seconds after LEDs 1 & 4 stop flashing.
5. Input Power:
The LP1501 is powered by one of two ways (jumper selected, J3):
Power is supplied via the Ethernet connection using PoE or PoE+
Or local 12 Vdc power supply, TB4-3 (VIN), TB4-4 (GND)

Mercury Security © 2018 LP1501 DOC 10107-0064 REV 1.01 Page 4
6. Communication Wiring:
The LP1501 controller communicates to the host via the on-board 10-BaseT/100Base-TX Ethernet
interface.
7. Reader/Serial I/O Device Wiring:
Reader port 1 supports TTL (D1/D0, Clock/Data), F/2F, or 2-wire RS-485 device(s). Reader port 2 supports
TTL (D1/D0, Clock/Data), or F/2F. Power to reader port 1 is 12 Vdc at 300 mA maximum. The reader
connected to reader port 2 may be powered from the 12 Vdc auxiliary power supply output; TB4-1 and TB4-
2. Readers that require different voltage or have high current requirements should 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.
Reader port 1 can support up to eight 2-wire RS-485 remote serial I/O devices using MSP1 protocol or up
to two OSDP devices. If two OSDP devices are used, reader port 2 will not support a third reader. If only
one OSDP device is configured, then reader port 2 is available for a second reader. The maximum cable
length is 2000 ft. (610 m). Do not terminate any RS-485 devices connected to reader port 1.
When powering remote device(s) from the LP1501, be cautious not to exceed the maximum current limit.
Cable gauge must also be evaluated. See specifications section for details.

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.
The input circuit wiring configurations shown are supported but may not be typical:
9. Relay Circuit Wiring:
Two Form-C contact relays are provided for controlling door lock mechanisms or alarm signaling devices.
The relay contacts are rated at 2 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 EMF feedback to the relay circuit that can cause damage and
premature failure of the relay plus affect the operation of the LP1501. For this reason, it is recommended
that either a diode or MOV (metal oxide varistor) be used to protect the relay. Wire should be of sufficient
gauge to avoid voltage loss.
From the Auxiliary output, the LP1501 can provide 12 Vdc power for external devices provided that the
maximum current is not exceeded. See the specifications section for details. If a local power supply is
used, it must be UL Listed Class 2 rated.

10.Memory Backup Battery:
The SRAM is backed up by a rechargeable battery when input power is removed. This battery should
retain the data for a minimum of 3 days. If data in the SRAM 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.
Note: The initial charge of the battery may take up to 48 hours to be fully charged.
11.Status LEDs:
Power-up: All LED's OFF.
Initialization: After power is applied, LED 1 is ON for about 15 seconds, then LED’s 2 through 7 are flashed
once at the beginning of initialization. LEDs 5, 6 and 7 are 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 through 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. If clearing the memory
does not correct the initialization problem, contact technical support.
Running:
After initialization is complete, the LEDs have the following meanings:

Note 1: If this input is defined, every three seconds the LED is pulsed to its opposite state for
0.1 seconds, otherwise, the LED is off.
12.IT Security
When installing the LP1501, 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 LP1501 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
LP1501 is commissioned. It is also highly recommended not to configure the LP1501 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.
