Monitor and Control Unit (MCU)

The MCU is the monitor and control unit. It has 8 selectable sensor inputs for monitoring ATM status. The sensor

inputs contain normally-open (NO), normally-closed (NC), and an optical isolated inputs. The MCU also contains

on-board sensors for tilt, continuous motion, light sensor(s), and thermal violation. Details about the inputs may

be found in section 2.0 Installation Guides and in section 4.0 Functional Operation.

The external sensor inputs are accessed either through a RJ45 style connector or by direct interface into terminal

block on the PCB. As with the CSU a user accessible self-test button is provided for troubleshooting and

installation. On the MCU printed circuit board there are several jumper blocks present to enable/ disable certain

functionality.

Outputs include two RJ11 remote interface monitors and a terminal block for the optional smoke generator.

Internal to the unit is an RJ11 connector for future expansion of the system to allow remote communications.

Basic MCU installation is made by wiring in external sensors, configuring the unit functionality via the on-board

jumpers, and mounting the MCU inside the ATM safe.
