0 1 A security system uses a motion sensor, a keypad and an alarm bell.

The system operates as follows:

• the system is initially off
• when the system is switched on it goes into sensing mode
• the system can be switched off at any time by entering the correct code on the
keypad
• if the system detects movement while in sensing mode it goes into alert mode
• after the system has been in alert mode for 10 seconds, it enters the alarm bell
ringing mode
• if an incorrect code is entered on the keypad, once the system has been switched
on, the system remains in its current mode.

Figure 1 shows a partially completed state transition diagram that represents the
operation of the security system. Three of the states are labelled (X) to (Z) and events
are labelled (A) to (I).
