Coverage Input (C) Input C represents the first input to the system and the level of coverage that the client has for the security system. Input C has values ranging from 0-7. The coverage level will determine what happens when an alarm is triggered and an action is requested. Coverage levels 0, 1, and 2 will allow a signal to the 'call centre'. Coverage levels 3 and 4 will allow a call directly to the 'security company'. Coverage levels 5, 6, and 7 will allow a call to the 'police'. Coverage levels 0, 1, 2, 3, and 4 will allow the owner to 'cancel' the alarm (calls to the police cannot be cancelled).

Input A has values ranging from 0-3. Action 0 is to try to call the 'call centre'. Action 1 is to try to call the 'security company'. Action 2 is to try to call the 'police'. Action 3 is to cancel the alarm. A value A1 A2 Action Try 'call centre' Try 'security company' WN - C Try 'police' Try 'cancel' Outputs (01, 02, 03, 04) The four outputs (01, 02, 03, and 04) are 1-bit outputs that are either 1 or 0 and represent what action has been taken based on the C and A inputs. If an output is 1 then the action is successful because the service coverage allows the action. If an output is 0 then that action is not currently valid because the service coverage does not allow the action. A maximum of one output can be valid (i.e. 1) at a time. 01 corresponds to a call to the 'call centre'. 02 correspond to a call to the 'security company'. 03 corresponds to a call to the 'police'. 04 corresponds to 'cancel'.
