    Powering HID® Mercury™ MR16in-S3 Processor Trusted Identities Installation and Specifications 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.
  • Page 7 Powering HID® Mercury™ MR16in-S3 Processor Trusted Identities Installation and Specifications 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).
  • Page 8: Relay Outputs

    Powering HID® Mercury™ MR16in-S3 Processor Trusted Identities 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.
  • Page 9 Powering HID® Mercury™ MR16in-S3 Processor Trusted Identities Installation and Specifications 2.5 DIP switch and jumper 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.
