The Software Acceptance Tests shall include the following:
a) Unit Testing
Unit testing refers to tests that verify the functionality of a specific section of code, usually at the function level. In an object-oriented environment, this is usually at the class level, and the minimal unit tests include the constructors and destructors.
b) Integration Testing
Integration testing is any type of software testing that seeks to verify the interfaces between components against a software design. Software components shall be integrated in an iterative way.
c) System Testing
System testing tests a completely integrated system to verify that it meets its requirements.
d) System Integration Testing
System integration testing verifies that a system is integrated to any external or third party systems defined in the system requirements.
e) Regression Testing
Regression testing focuses on finding defects after a major code change has occurred.
f) Acceptance Testing
Acceptance testing involves running a suite of tests on the completed system. Each individual test, known as a case, exercises a particular operating condition of the user's environment or feature of the system, and will result in a pass or fail boolean outcome. The test environment must be designed to be identical, or as close as possible, to the anticipated user's environment, including extremes of such. These test cases must each be accompanied by test case input data or a formal description of the operational activities (or both) to be performed—intended to thoroughly exercise the specific case—and a formal description of the expected results.
g) User Acceptance Testing
After the Contractor has completed the Acceptance Testing and the software has passed all the test cases, the Contractor shall submit the full test report to the Employer. After approval of the full test report by the Employer, the Contractor shall schedule the User Acceptance Testing. The Employer, Operator and/or Engineer shall participate in and witness the User Acceptance Testing. The User Acceptance Testing outcome must be approved by the Employer before the system can be deployed into operation or production.

2.32.20 All logged data are automatically summarized each night for historical reports. Users have the option to print out the standard reports included with the SCADA System or create their own reports by requesting the SI to implement a new report type. All logged data can also be imported into Microsoft Excel.
2.32.21 There are four report types in the Report Module that an operator can select and each report type displays data from a different viewpoint over a specified period selected by the user.
VOLUME 2 BOOK 4b: STANDARD SPECIFICATION FOR ELECTRONIC WORKS
- 79 -
Daily - prints and displays a report of hourly averages and totals for the date selected. The user may select Month, Day, Year and Starting and Ending Hour in military time for the report. Weekly - prints and displays a report of daily averages and totals for seven days from a beginning date. The user may select Month, Day, and Year. The date is the first day of the reported week. Monthly - prints or displays a report of the daily averages and totals for a selected month and day range. The user may select Month, Year and Starting and Ending days for the report. Yearly - prints or displays a report of the monthly averages and totals for a selected year and month range. User may select Year and Starting and Ending months for the report.
2.32.22 Each Report Style (Period and Instance) is used differently according to the selected Report Type (Daily, Weekly, Monthly and Yearly).
2.32.23 Period Reports are intended to show totals and averages for a time frame. Instance Reports are intended to show the actual values at an instant in time.
2.32.24 Reports are:
Detail Reports - using up to 10 variables per report, these reports break down one site in hourly format for daily reports, daily format for weekly and monthly reports, and monthly format for yearly reports. Also, Detail Reports can be set up for one variable over several sites. These reports are usually used to troubleshoot a site or sites at 24-hour intervals. Summary Reports - give the totals or averages for all sites at once. These reports are the best for typical system reports and helpful in locating a site that needs watching more closely. Combination Reports - allow several daily reports to be printed at once. The best use for this report style is for monitoring several sites over several days. It saves the user time printing several daily reports at one time instead of each report being selected and printed one by one. Graphs - allow trends to be seen quickly and can be viewed in several formats. The trends can be set up to display the system's averages or one site's averages. The graphs can be viewed in 2-D or 3-D with bars, lines, curves, etc. The graph data can be copied to the clipboard, titles can be changed, and the scale can be changed.
2.32.25 Instance Reports are:
History Reports - show every variable logged by the system with a timestamp and can be set up for all sites at once in a
VOLUME 2 BOOK 4b: STANDARD SPECIFICATION FOR ELECTRONIC WORKS
- 80 -
group or one site at a time. The number of data types is selectable from all to one. Though this is a great debugging tool, it is recommended to print one site at a time because this report can become very long. Last Instance Reports - show the last polled value for all sites at once or in a group or for the specific selected item i.e. fuel level of a specific generator. This report is the best way to see the system's current state.
2.32.26 The SCADA shall have the function to export any report to PDF or excel format.
2.33 OBJECT ORIENTED GRAPHICS
2.33.1 Mimic screens shall be graphically based on dynamic and static objects (where possible, real images of the equipment shall be used). The system shall support true vector based graphics and allow unlimited panning and zooming without any degradation in mimic resolution and sharpness. There shall be no limitation to the screen resolution and/or number of colours supported. A comprehensive standard graphics symbol library shall be provided that will allow modification and/or adding of custom symbols to the library easily without requiring additional software. All library symbols shall support unlimited panning, zooming and sizing. It shall be possible to dynamically move, size and rotate all graphic objects linked to changes of state in the online database.
2.33.2 The package shall have conventional CAD type editing facilities to ensure that the mimics are easy to build and modify. It shall be possible to launch third party applications from within a graphic page, by operator action or on process event, as well as configure user-specified, process-triggered, hypertext help pages for display.
2.33.3 The SCADA system shall allow mimics to be “replayed” from historically logged data as well as live real-time data. The Operator must have the ability to simply toggle a real-time mimic into historical mode. The replay feature shall be in-built and should not require additional configuration. The SCADA shall support dynamic toll tips allowing multiple tags to be configured and updated in the toll tip.
2.33.4 User Interface adaptability will allow for the creation of new presentation layer objects such as pictures trends, wizards, templates, animation behaviours, alarm and event views, etc. Templates shall be supported for trends and graphic pages. The tag assignment shall depend on the selection of the common plant areas.

VOLUME 2 BOOK 4b: STANDARD SPECIFICATION FOR ELECTRONIC WORKS

3.3.2 Detection Elements
3.3.2.1 The ability to detect is at the heart of eliminating the probability of success of the criminal mission. Detection is a process that includes sensing, processing, transmitting the detection and reporting it to someone who can act.
3.3.3 Minimum Requirements for Alarm Sensors per site
3.3.3.1 The following are the minimum requirements for the alarm sensors for the Security System:
a) Point detection
b) Beam detection
c) Volumetric detection
d) Relay detection
e) Alarm Processors
3.3.3.2 In most cases involving sophisticated security systems (including all enterprise security systems), the detection is processed locally before it is transmitted. Processing may involve simple decisions such as whether or not the detection is occurring during an appropriate time period (e.g. volumetric alarms in an office building lobby during normal working hours). The processing may be more extensive such as checking to determine whether a group of conditions is satisfied before triggering the alarm. The processing typically occurs in an alarm and access control system controller. The processor will usually also perform a check to ensure that the detection was received correctly.
3.3.4 Alarm Transmission
3.3.4.1 As soon as the alarm is processed, it must be transmitted to someone who can take action on the detection. Almost all integrated alarm system today use TCP/IP Ethernet connections and are sometimes converted to fibre optic or wireless (802.11 or other) mediums.
3.3.4.2 Minimum Requirements for alarm transmission per site
3.3.4.3 The following are the minimum requirements for alarm transmission for the Security System:
a) TCP/IP Ethernet connections
b) Converted to fibre optic for the backbone transmission
c) Fibre Optic backbone between remote locations and the Command Centre at the Central Operation Centre.
VOLUME 2 BOOK 4b: STANDARD SPECIFICATION FOR ELECTRONIC WORKS
- 95 -
3.3.5 Alarm Reporting
3.3.5.1 The detection is received by a monitoring device and is acknowledged by a person who can act on it. In enterprise security systems, the detection is almost always displayed on a computer with specialized software that is also capable of integrating access control, CCTV, voice communications and ancillary systems e.g. two-way radio, private automatic branch exchange (PABX), elevators, building automation and information technology.
3.3.6 Follow-on Action
3.3.6.1 Following detection and assessment, the security system should assist in preventing an adversary from successful completion of a malevolent action against a facility. Follow-on action is that integrated element which allows the enterprise security system to do some interesting things e.g. based on detection of an intrusion into a highly restricted area, the system can implement delaying barriers which might include dispatching personnel, activating vehicle or pedestrian barriers (rising bollards or roll-down doors), switching off all lights and disorientating audio signals (sounding alarms within the structure which raises the anxiety level of the intruder) to disrupt the progress of the intruder. Follow-on actions can also facilitate access for a legitimate user, such as turning on lights from a parking garage through lobbies, corridors and to the exact office of a card holder.
3.3.7 Assessment and Verification Elements
3.3.7.1 Some alarm notifications are nuisance conditions and not a real alarm and it is therefore important to vet all alarms so as not to respond to a tree branch falling against a perimeter fence. There are several ways that assessment can be achieved:
a) Guard response assessment: dispatch a guard to check the alarm condition. This takes time and is costly. The delay before assessment is not desirable and it is possible that by the time the guard arrives at the alarm site, the person who caused it may be gone and therefore no verification is possible even though the alarm notification was real. Guard response assessment is not ideal.
b) Second alarm sensor assessment: an alarm can also be verified by the activation of a second alarm. Although it is possible for a single nuisance alarm to occur, it is less likely that two nuisance alarms could occur in rapid succession. Alarms can therefore be linked to confirm each other.
c) Audio assessment: in parking structures and other remote areas, audio alarms that respond to specific sounds such as a person screaming in alarm or fear are often used. The same microphone that caused the alarm can then be used to confirm it. By listening to the area where the alarm occurred, a console guard can confirm that the noise that activated the alarm was a real event.
d) Video assessment: one of the most common forms of assessment is with video cameras. A guard can observe the condition at the scene of the alarm very quickly and this is a precise way of verifying alarms.

3.3.8 Minimum Requirements for Assessment and Verification Elements per site
3.3.8.1 The following are the minimum requirements for the assessment and verification elements for the Security System:
a) Second alarm sensor assessment
b) Video assessment.
3.3.9 Reaction Elements
3.3.9.1 After an alarm is verified, the organisation may choose to act on it. Options include deterring the intruder, delaying him or her or disrupting the intrusion. This requires reactive electronic automated protection systems (REAPS). There are three common types of REAPS:
a) Communication elements: the most basic and least expensive method is to communicate with the intruder. Only the most determined intruder will continue after he or she is interrupted in the act. Security intercoms are often an effective and economical tool, which can be used to stop intruders in their tracks.
b) Deployable barriers: more sophisticated systems utilise deployable barriers including rising bollards and wedges to stop vehicles, and electrified locks, roll-down doors and deployable operable walls to delay pedestrians. Environment disruption devices can be used to delay an intruder until a more formidable response force can arrive and take control of the offender.
c) Attack disruption: in high security environments, it may be necessary to actually disrupt the intrusion or attack. This can include deployable smoke, fast setting and sticky foam dispensing systems, drop chains, explosive air bags, automated weaponry, deluge water systems, acoustic weapons etc. All of these have the common element of making it much more difficult for an attack or intrusion to continue and can result in the capture of the attacker or intruder. There are two types of attack disruption systems, non-lethal and lethal. Even some non-lethal systems can cause injury. In either case, it is important to implement safety measures in the activation mechanism to ensure that accidental activation does not occur and injure innocent people.
d) Evidence gathering, storage and retrieval: one of the key elements of enterprise security systems is their ability to log alarms and events and to record video and audio which can serve as the evidence required to build a case against a criminal offender.
e) Policy enforcement: one of the key capabilities of enterprise security systems is the ability to support safety, business ethics and security policy enforcement. The ability to detect improper behaviour, assess it as a real event and use the evidence to support additional training or enforcement is of tremendous value to any organization. The systems can also help to determine chronic or determined policy abusers and provide the evidence necessary to weed out employees or contractors who are working against the best interests of the organization. On the most basic level, access control systems
