Basic Operation:
A high level functionality follows, but for more detailed operation use the flow diagrams and the discussion on
page 14. Software flow diagrams on pages 15 to 18, shows operation of the Octopus ATM Defense System.
Following the flow diagram each state and its characteristics are discussed in detail.
1. With the CSU installed in the cassettes and the MCU installed in the ATM safe cavity. If power is supplied
to the MCU and CSUs they will be in STANDBY mode. STANDBY is the lowest level of protection,
allowing service and maintenance of the sensors, cassettes, and the ATM itself without fear of activation.
While in this mode, it is possible to detect and correct all sensor errors by using the press-to-test button
located on the MCU.
2. TEST mode may be selected by holding down the POST button while removing and re-installing power to the
unit. See Appendix T for detailed description.
3. Holding the POST button for 2 seconds and then releasing it will perform system self-test. See Appendix A
for Self-Test operation and detailed description.
4. Securing the door will upgrade the system status to ARMED mode. In Level III and Level V operation this is
simply closing the ATM door or actuating the door contact switch. Level II operation requires a bolt indicator
switch to check for authorized door opening. The process steps are discovery (find all units), self-test (find all
errors or faults), report (beep indicate self-test status). This take 10-12 seconds.
5. While armed, the system will wake every second to check for polled alarms, react instantly to interrupt driven
alarms, and periodically poll the CSU to get status and sensor information. Any sensor or input error is
disabled from operation during the STANDBY to ARMED process.
MCU alarms that lead from ARMED to ALERT mode, which are processed every second are:
a) Thermal variation and
b) Motion > 15 seconds.
c) Light detection (in Level V only).
MCU alarms that lead from ARMED to ALERT mode, which are interrupt processed are:
a) Generic NO input # 1,
b) Generic NO input # 2,
c) Generic NC input # 1,
d) Generic NC input # 1 (or Bolt Indicator in Level II), and
e) Power Loss (if power was monitored).
MCU alarms that lead from ARMED to FIRE mode, which are interrupt processed are:
a) Thermal violation (> 72ºC or < 0ºC)
b) Tilt > 2 seconds
c) Manual Fire / Breach.
No CSU alarms lead from ARMED to ALERT or to STANDBY.
6. To disarm an ARMED system follow authorized procedure and open door. In Level III and Level V operation
this is simply opening the ATM door or de-actuating the door contact switch. Level II operation requires a
bolt indicator switch to check for authorized door opening.
7. Activation of any sensor leading to the ALERT mode places the CSUs into ALERT mode. They then activate
their internal sensors (Tilt, Light, Thermal) and listen for instruction from the MCU. The CSUs beep one time
per second to indicate the ALERT mode.
