An alarm device or system of alarm devices gives an audible, visual or other form of alarm signal about a problem or condition. Alarm devices are often outfitted with a siren.
Alarms in an operation and maintenance (O&M) monitoring system, which informs the bad working state of (a particular part of) the system under monitoring. First-out alarm safety alarms, which go off if a dangerous condition occurs.

  1. 1. “DESIGN OF ALARM USING PIR SENSOR FOR TEMPERATURE DETECTIONS” Given by: Akshay Dhole 13MMT1013 (Mechatronics)
  2. 2. INTRODUCTION:  An alarm device or system of alarm devices gives an audible, visual or other form of alarm signal about a problem or condition. Alarm devices are often outfitted with a siren.  Alarms in an operation and maintenance (O&M) monitoring system, which informs the bad working state of (a particular part of) the system under monitoring. First- out alarm safety alarms, which go off if a dangerous condition occurs.
  3. 3. Common public safety alarms include:  Civil defense siren also known as tornado sirens or air raid sirens fire alarm systems  Fire alarm notification appliance  "Multiple-alarm fire", a locally-specific measure of the severity of a fire and the fire-department reaction required.  Smoke detector  Car alarms  Auto dialer alarm, also known as community alarm  Personal alarm  Tocsins – a historical method of raising an alarm
  4. 4. FUNCTION:  The primary function of the alarm system is to warn the operator about a situation that is not normal.  The system should inform the operator about plant conditions that require timely assessment and possibly corrective action in order to maintain plant goals in terms of safety, productivity, environment and efficiency.
  5. 5.  Alarms should: 1. Be relevant to the operator's role at the time 2. Indicate what response is required 3. Be presented at a rate that the operator can deal with 4. Be easy to understand
  6. 6. Specifications of design  Dimensions: 30* 30* 30  Power requirement: 12V, 5V  Audio range: 40M  Max. Number of alarms: 2  Speed of sensing: HIGH  Light in weight  Alarm Graphical Warning display
  7. 7. Functional requirements  The alarm system shall be explicitly designed to take account of human factors and Limitations.  context sensitive.  The alarm system design shall be based on an alarm philosophy.  The alarm system shall be properly documented, and clear roles and responsibilities shall be established for maintaining and improving the system.  It should be easy for process experts to build into and maintain knowledge and intelligence in the alarm system over time.
  8. 8. Design requirements  Step Down Transformer  Regulator Ics For 12v, 5v  Sensor- Pir Sensor  2 Stage Opamp, Comparator  Transistor Switch  Relay  Light Or Lamp  Alarm Generator Or Buzzer
  9. 9. Architecture
  10. 10. SOFTWARE:  The software used: Keil u-vision..
