for the P-1.00 Alarm System

1.1 An Overview of the Unit

The P-1.00 Prototype Alarm System is made up of 4 major parts: An input 6-button keypad acts as the arming and disarming mechanism. There are a total of 5 different input "triggering" components (4 push buttons and 1 motion sensor), which alert the user of a security system breach via the LCD display screen and the siren port.

1.2 How To Begin

Power must first be supplied to the Evaluation Board, the Speakers and the Motion Sensor Light. The speakers must then be turned on after the proper programming sequences have taken place (using IASM12 and MAX PLUS). The system will then be set into a "System Ready" state (displayed on the LCD), which will allow the user to arm the alarm assuming certain conditions are met. The LCD will display the current status of all "triggering" inputs. If any of these inputs are tripped, you must wait until they are all disengaged ("low") before the alarm can be armed.

1.3 Arming the Alarm

When all inputs are "low", in order to engage the alarm, enter your 4 digit combination using the 6-button keypad (1234 in our case). Upon completing this, the LCD screen will display "System Armed" and the program will wait until one of the inputs is triggered.

1.4.1 Disarming the Alarm (When Sensor Has Been Tripped)

When a sensor is tripped, the status of the system will be indicated on the second line of the LCD screen explaining to the user which sensor has been activated. At this point the user has the opportunity to disarm the alarm. If this action is desired the user must wait until all sensors are "low". When this condition is met the user may type the combination into the 6-button keypad. When the correct combination has been entered the program returns to its "System Ready" state. Thus, in order for the alarm to be activated again, simply follow the instructions as outlined in 1.3 Arming the Alarm.

1.4.2 Disarming the Alarm (When the System Is Not Tripped)

When the system is armed, it constantly checks for tripped sensors. If no sensor is tripped and the user wishes to disarm the alarm, he/she must press any button on the key pad and then immediately after enter the combination. This action will cause the alarm system to return to its "System Ready" state. Thus, in order for the alarm to be activated again, simply follow the instructions as outlined in 1.3 Arming the Alarm.
