The contractor should demonstrate that all system software, especially its security components, works as intended. For small or simple systems, this test may involve wiring some simulated signals (toggle switches, lights, analog signal from a signal generator, etc.) to the control panel. For larger or more complex systems, this test should involve the use of simulation software installed on a separate computer. During this test, the contractor should demonstrate operation and display of all software based on a simulation involving 100% of physical I/Os, including analog, discrete, and virtual I/Os.
