M5-2K Four Reader Interface Board
Installation and Specifications:
1. General:
Mercury’s M5-2K board for the Micro/PX-2000, Micro/PXN-2000, and MicroPXNplus® systems (M2000
enclosure) is part of Mercury Security's bridging hardware technology and provides four reader interface
ports. The M5-2K board accepts data from readers with F/2F, and supervised F/2F signaling and door
hardware. The M5-2K board provides ten inputs (un-supervised/supervised), eight Form-C control relays,
12 Vdc power supply to power readers and other devices.
The M5-IC controller board can be mounted directly on the M5-2K board or in a Micro5®enclosure.
If the M5-IC is mounted on the M5-2K board, it is powered by the M5-2K board’s internal power supply.
Power for the M5-2K board is supplied from an 18 Vac transformer. The M5-2K supports the charging of
an optional 12 Volt, 7 Ah rechargeable sealed lead-acid battery for UPS operation.
This installation manual does not contain the M5-IC controller board configuration information; see
the M5-IC Controller Board Installation and Specifications manual, DOC 10107-0040.
2. Installing the M5-2K Board:
The M5-2K and M5-IC boards replace the current M2000 enclosure’s circuit boards.

3. Input Power, 12 Vdc Output, Tamper Switch, and 12 Volt Battery Wiring:
Input power for the M5-2K/M5-IC assembly is provided by a wall mount 18 Vac transformer @ 2.78 A
(334 VA) connected to TB8 pins 1 and 2. The internal supply supplies power to the M5-2K/M5-IC
assembly, and charging current for a 12 volt, 7 Ah rechargeable battery. 12 Vdc output is also available
to power local devices (door strikes, annunciator devices, etc.), and downstream M5-2K enclosures. The
UPS 12 volt battery is connected to TB8 pin 7 (+) and TB8 pin 8 (-). There is a dedicated input for cabinet
tamper, connected to TB8-5 and TB8-6. Normal (safe) condition is a closed contact.

Do not use a 24 Vac transformer to power the M5-2K/M5-IC assembly!
There must be no wires connected to TB1 of the M5-IC!
4. Ethernet Grounding:
The grounding lug on the M5-IC, identified “CGND” (located next to the Ethernet jack), must be
connected to the chassis/earth ground stud on the M200 enclosure. It is recommended to use braded
wire and make the connection as short as possible.
5. RS-485 Communication Wiring:
The M5-IC communicates to the M5-2K using 2-wire RS-485 on downstream communication port 1. This
communication port also appears on TB7 of the M5-2K. An additional 31 downstream I/O devices can be
supported on this communication port.
If the M5-IC is mounted on the M5-2K, TB2 of the M5-IC is the 2-wire RS-485 downstream
communication port 2, which can communicate to an additional 32 downstream I/O devices.

7. Reader Wiring:
Each of the four reader ports support F/2F, and supervised F/2F type readers.
Reader cable requirements: See specification section for more details.
F/2F and supervised F/2F readers require a shielded 4-conductor cable.

8. Door Position Monitor and REX Input Wiring:
The door position monitor and REX switches can be wired in two different configurations.
1. Supervised F/2F readers: door contacts and REX inputs are to be wired through the reader
2. F/2F readers: door contacts and REX inputs must be wired to the M5-2K inputs, see Section 9
Typically, the door position monitor switch uses the Normally Close (NC) contact and the REX uses the
Normally Open (NO) contact. Some supervised F/2F readers support different switch configurations
which are defined in the host and downloaded to the M5-2K.
Supervised Inputs - Wired to Supervised F/2F Reader, 4-State Supervision:
Supervised inputs for the door position monitor and REX switches are wired directly to the supervised
F/2F reader configured for 4-State Supervision. See reader’s documentation for the proper connection
terminals. Typically, the EOL resistors are two 1K ohm resistors as shown below. The EOL resistors
should be installed as close to the switch as possible.

Unsupervised Inputs - Wired to Supervised F/2F Reader, 2-State Supervision:
Unsupervised inputs for the door position monitor and REX switches are wired directly to a supervised
F/2F reader configured for 2-State Supervision. See reader’s documentation for the proper connection
terminals. EOL resistors are not required.
Supervised F/2F Reader 2-State Input Wiring
9. Input Wiring:
Typically, these inputs are used to monitor door position, request to exit, or general purpose alarm
contacts. Input circuits can be configured as unsupervised or supervised. When unsupervised, reporting
consists of only the open or closed states.
When an input circuit is configured for supervision, the M5-2K board also monitors the following abnormal
circuit conditions: open circuit, shorted circuit, grounding of either side of the circuit*, or the introduction of
a foreign voltage*. A supervised input circuit requires adding two resistors 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.

10.Door Strike Wiring using an External Relay:
Instead of using the on-board relay to control the door strike, an external relay may be used. This
external relay is controlled by the reader DOx output.
If the LED in the reader is driven by the reader port DOx signal, a blocking diode must be added to the
circuit. This blocking diode should be a Schottky barrier rectifier, type 1N5817 or equivalent (20 volt @ 1
A).
Important note:
The external relay’s coil current must be restricted to 40 mA. The coil resistance of a 12 volt relay
must be 300 ohms or greater.

11.Door Strike Wiring using the Internal Relays:
The M2-2K board has eight Form-C contact relays for controlling door strikes or other devices. Relay
contact rating: 2 A @ 30 Vac/dc maximum.
Excessive load switching causes contact wear and premature failure. Inductive load (strike)
switching causes EMI (electromagnetic interference) which may interfere with normal operation of
other equipment. To minimize premature contact failure and to increase system reliability, a
contact protection circuit must be used. Locate the protection circuit as close to the load as
possible (12 inches [30cm] maximum recommended). The circuit's effectiveness decreases if it is
located further away.
Use sufficiently large gauge wire for the load current to avoid voltage loss.
