Section 01
Overview
1.1 MR16in processor
The MR16in processor provides a solution to the OEM system integrator for sensor monitoring and output control.
The MR16in has sixteen non-supervised/supervised inputs and two Form-C contact relays for load switching. In addition,
two digital inputs are used for cabinet tamper and power fault status monitoring.
The MR16in processor requires 12 to 24 V DC for power.

MR16in wiring and setup
2.1 Supplying power to the MR16in
The MR16in accepts 12 to 24V DC for power. Locate power source as close to the unit as possible.
Connect power with minimum of 18 AWG wire.
Observe POLARITY on VIN!
The VOUT terminal on TB11 is the same as VIN.
2.2 Communication wiring
The MR16in communicates with an intelligent controller (EP2500 for example) via a 2-wire RS-485 interface. The
interface allows multi-drop communication on a single bus of up to 4,000 feet (1,200 m). Shielded cable of 24 AWG with
characteristic impedance of 120Ω is specified for the RS-485 interface. See Specifications.
Install RS-485 termination jumper, J3, on the interface boards at each end of the communication line only.
2-wire RS-485
(only 2-wire RS-485 is supported)

2.3 Alarm inputs wiring
Inputs 1 to 16 may be configured to use or not use End Of Line (EOL) resistors, and to use normally open or normally
closed contacts.
Input CT and input BA are used for monitoring cabinet tamper and power failure, respectively. These two inputs are for
contact closure monitoring only, and do not use EOL resistor(s).
Input configuration is set via host software.

Installation and Specifications
2.4 Relay outputs
Two 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. To minimize premature contact failure and
to increase system reliability a 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 inches [30 cm]), as the effectiveness of the circuit
will decrease if it is located further away.
Use sufficiently large gauge of wire for the load current to avoid excessive voltage drop.
Diode selection
lDiode current rating > 1x strike current.
lDiode break down voltage: 4x strike voltage.
lFor 12 V DC or 24 V DC strike, diode 1N4002 (100V /1A) typical.
