define SIMULATION a and what is the need of it..

simulation means (The act of giving a false appearance of input or signal)
to our system so that we can check our loop, response of relative outputs, to bypass the protection,
For example
1.to check smoke, heat detectors response we apply magnet to activate its relay to energize a false fire signal to system.
2.to check our loop during commissioning we apply mAs and get values in CCR.
3.whenever such situation has to face that an erratic signal persisting protection and machine cannot start so we can apply necessary pulse to our logic and start our machine.
