CKM-MR52-S3 READER TERMINAL MODULE
This document provides hardware installation and setup instructions for
CKM-MR52-S3, the authentic Mercury™ dual reader terminal module
Series 3. This document is divided into the following sections:
•General Information on page 1
•Mounting Information on page 2
•Wiring Information on page 2
•Jumper and DIP Switch Usage on page 7
•Status LEDs on page 9
•Specifications on page 11
•Maintenance on page 12
NOTE: Throughout this manual the CKM-MR52-S3 module is also referred to as
the CKM-MR52.
GENERAL INFORMATION
The CKM-MR52 reader interface provides a solution to the OEM system
integrator for interfacing to TTL, Wiegand, or RS-485 type readers and door
hardware. The CKM-MR52 can accept data from reader with clock/data,
Wiegand, or RS-485 signaling, and provide a tri-stated LED control and buzzer
control. Six form-C relay outputs may be used for strike control or alarm
signaling. Eight supervised inputs are provided for monitoring the door contact,
exit push button, and alarm contacts. Communication to the CKM-MR52 is
accomplished via a 2-wire RS-485 interface.
The CKM-MR52 requires 12 to 24 VDC for power. See the following figure
for component location.

Cable Routing
The cables should run in grounded conduit or at least two feet from AC
power, fluorescent lights, or other high energy sources.
IMPORTANT: All data cables should be physically separated from power lines. If
conduit is used, do not run data cables in the same conduit as power cables or
certain door strike cables, e.g. strike voltage greater that 42V or Magnetic door
locks without EMI suppression.
All cables must conform with the following regulations:
• National Electrical Code
•NFPA 70
• Local electrical codes
• Canadian Electric Code C22.1 (installations in Canada)
• BSI Standard BS7671, latest edition (installations in Great Britain)
Cabling should be made using good wiring practices and should be long
enough to allow service loops at their terminations in the enclosure.
Power Wiring
The CKM-MR52 accepts 12 to 24 VDC for power on TB7. Locate the
power source as close to the CKM-MR52 as possible. Make power
connection with minimum of 18 AWG wires.

Communications Wiring (SIO Communication Port)
The CKM-MR52 communicates to an intelligent controller (for example,
CKM-EP2500) via a 2-wire RS-485 interface. The CKM-MR52 allows
for multidrop communication on a bus of up to 4,000 feet (1,200 m). Use
twisted pairs (minimum 24 AWG) with drain wire and shield for
communication. See Specifications for details.
Install RS-485 termination jumper, J4, on the interface boards at each end
of the communication line only.
Figure 3 shows the CKM-MR52 communications wiring.
Figure 3: CKM-MR52 Communications Wiring
Reader Wiring
Each reader port supports a reader with TTL (D1/D0, Clock/Data) or 2-wire
RS-485 signaling. Power to the reader is selectable: 12 VDC (VIN must be
greater than 20 VDC), or power is passed-through (PT) from the input voltage
of the MR52 (TB7-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.

CKM-MR52-S3 Hardware Installation Manual
24-10707-198 Rev. –

To fully utilize each reader port:
• TTL signaling requires a 6-conductor cable (18 AWG)
• 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).

NOTE: If the input voltage to the MR52 is 12 VDC, jumper J1 must be in the PT
position.

Alarm Contact Wiring
There are 8 inputs that are typically used to monitor door position,
request to exit or alarm contacts. Input circuits can be configured as:
• Unsupervised alarm (2 states); reporting as open or closed contact.
• Supervised alarm (6 states); reporting as open or closed contact, open
circuit, shorted circuit, grounded circuit *, or foreign voltage*.
A supervised input circuit requires adding two resistors with value of 1k
Ohm, 1% to the circuit to facilitate proper reporting 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.
Figure 7: CKM-MR52 Alarm Contact Wiring
There are two additional inputs for monitoring cabinet tamper (TMP) and
power failure (PFL). These two inputs do not use EOL resistors and are
for contacting monitoring only.
Control Output Wiring
Six form-C contact relays are provided for controlling door strikes or
other devices. Load switching can cause abnormal contact wear and
premature contact failure. Switching of inductive loads (strike) also
causes EMI (electromagnetic interference) which may interfere with
normal operation of other equipment.

CKM-MR52-S3 Hardware Installation Manual
24-10707-198 Rev. –

To minimize premature contact failure and to increase system reliability,
contact protection circuit must be used. The following two circuits are
recommended. Locate the protection circuit as close to the load as
possible, within 12 inches30cm), as the effectiveness of the circuit
decreases if it is located further away.
Use sufficiently large gauge of wires for the load current as to avoid
voltage loss.

JUMPER AND DIP SWITCH USAGE
Switches 1 to 5 select the device address. Switch 6 and 7 select the
communication baud rate. Switch 8 enables encrypted communication. All
other configuration settings are set via host software.
