eMAX-MR50 SINGLE DOOR CONTROLLER
Series 3
1. General:
The eMAX-MR50-S3 Single Door Controller provides a solution for interfacing to a TTL (D1/D0, Clock/Data),
F/2F or RS-485 Reader-type devices, and associated door hardware. It also provides for tri-stated LED control
and buzzer control. Two Form-C contact relay outputs may be used for door lock control or alarm signaling.
Two inputs are provided that can be used for monitoring the door contact and request to exit device. Input
circuits can be configured as unsupervised or supervised. Communication to the eMAX-MR50-S3 controller is
accomplished via a 2-wire RS-485 interface. The eMAX-MR50-S3 requires 12 to 24 Vdc for power.
2. eMAX-MR50 Hardware:
The eMAX-MR50-S3 requires filtered 12 to 24 Vdc ± 10% for power. Two inputs on the board are typically
used for door contact and exit request monitoring. End of line resistors are required for supervision, shown
below.
Note: The input power is passed through to the reader terminal strip and is available for powering a reader.
Readers that require different voltage requirements must be powered separately. Care must be taken to ensure
that the input voltage is within the voltage range of the reader. The reader power output terminal, TB4-6 (VO),
is not current limited.
Note: Refer to the eMAX-EP controller Installation and Specifications manual for proper grounding details.

3. Reader Wiring:
The reader port supports a reader with TTL (D1/D0, Clock/Data), F/2F, or 2-wire RS-485 signaling.
**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.

4. Door Strike/Lock Relay Wiring:
Two (2) Form-C contact relays are provided for controlling the door strike/lock or other such devices. See
specifications section for the relay contact ratings. 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 and to
increase system reliability, contact protection circuit must be used. The following circuit wiring 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 far away. See documentation included with locking device regarding
suppression diode requirements.
Diode Selection:
Diode current rating: 1x strike current
Diode breakdown voltage: 4x strike

5. Communication Wiring:
The eMAX-MR50-S3 Controller communicates to a Maxxess EP Series Intelligent Area Controller (EP2500 for
example) via a half-duplex multi-drop 2-wire RS-485 interface. The total cable length is limited to 4,000 feet
(1,219 meters). Shielded cable of 24 AWG with characteristic impedance of 120 ohm is specified for the 2-wire
RS-485 interface. The last device on each end of the communication line should have the terminator installed
(install jumper J1).
