eMAX-MR52 DUAL DOOR CONTROLLER
Series 3
1. General:
The eMAX-MR52 Dual Door Controller (Series 3) provides a solution for interfacing to TTL (D1/D0, Clock/Data),
F/2F, or 2-wire RS-485 Reader-type devices and associated door hardware. It also provides tristate LED control
and buzzer control. The Boards includes six (6) form-C contact relay outputs which may be used for door lock
control or alarm signaling. Eight inputs are provided that may be used for monitoring the door contact, request
to exit devices, and other alarm contacts. Input circuits can be configured as unsupervised or supervised.
Communication to the eMAX-MR52-S3 is via a 2-wire RS-485 circuit. The eMAX-MR52-S3 requires 12 or 24
Vdc for power.
See the following figure for component location (some components shown are not present on the eMAX-MR52-
S3).

2. Supplying Power to the eMAX-MR52:
The eMAX-MR52-S3 accepts 12 to 24 Vdc for power on TB7
(VIN and GND). Locate the power source as close to the
eMAX-MR52-S3 as possible. Install the power connection
with minimum of 18 AWG wires.
Ensure that you observe POLARITY on VIN!
The VOUT terminal on TB7 is the same as VIN.
3. Communication Wiring (SIO Communication Port):
The eMAX-MR52-S3 communicates to a Maxxess EP
Series Intelligent Area Controller (EP2500 for example)
via a 2-wire RS-485 interface. The eMAX-MR52-S3
allows for multi-drop communication on a bus of up to
4,000 feet (1,200m). Use twisted pair (minimum 24
AWG) with drain wire and shield for communication. See
specifications section.
Install RS-485 termination jumper, J4, on the interface
boards at each end of the communication line only.

4. Reader Wiring:
Each reader port of the eMAX-MR52-S3 supports a reader with TTL (D1/D0, Clock/Data), F/2F, or 2-wire RS-
485 signaling. Source Power to the reader is selectable: 12 Vdc created on the Board (VIN must be greater
than 20 Vdc), or power that is passed-through (PT) from the input voltage of the eMAX-MR52-S3 (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 manufacturer specifications for cabling requirements.
J1 –Reader Port Power Select
!! - If the input voltage to the eMAX-MR52-S3 is 12 Vdc, jumper J1 MUST be in the PT position.
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)

5. Alarm Contact Wiring:
The eMAX-MR52-S3 includes 8 inputs that are typically used to monitor door position, request to exit devices,
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 (2) EOL resistors with value of 1k ohm, 1% to the circuit to
facilitate proper monitoring and reporting. The Resistors 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.
6. Inputs for Cabinet Tamper/Power Fault:
Input CT and input BA are used for monitoring cabinet tamper and power failure with normally closed contacts.
These two inputs are for contact closure monitoring only, and do not use EOL resistor(s). If these inputs are
not used, install a short jumper wire across the input to indicate a safe condition.

7. Control Output Wiring:
The eMAX-MR52-S3 include six (6) Form-C contact relays used for controlling door strikes/locks or other such
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. To minimize premature contact failure andto increase systemreliability, a contact
protection circuit must be used. The following circuit is recommended. Locate the protection circuit as close to
the load as possible (within 12 inches [30 cm]), as the effectiveness of the circuit will decrease if it is located
further away.
Use sufficiently large gauge of wires for the load current as to avoid voltage loss.
See documentation included with locking device regarding suppression device requirements.
DIODE SELECTION:
Diode current rating > 1x strike current
Diode break down voltage: 4x strike voltage
For 12 Vdc or 24 Vdc strike, diode 1N4002
