Modern alarm systems offer various functions such as burglar alarm, video surveillance, light and sound signaling, light switching and presence detection. In emergency situations such as theft, fire, flooding, etc., they alert people or alarm centres either with a loud siren or, depending on the system, with a silent alarm.
There are different types of motion detectors with different operating principles. Passive infrared, or PIR, detectors are the most commonly used and can be used both indoors and outdoors. Combinations of motion detectors are often used in intruder alarm systems to reduce the risk of false alarms. Dual PIR detectors, for example, consist of two different PIR sensors and only trigger an alarm if both sensors detect movement.
Of course, the alarm electronics also need to be protected. Surges from the mains, for example, from a lightning strike, can damage the sensitive sensor circuitry. The P6SMBJ5.0CA Transient Voltage Suppressor (TVS) from Diotec Semiconductor provides reliable surge protection for electronic alarm systems, has an operating voltage of 5 V and a peak power of 600 W, and is supplied in the space-saving DO-214AA/SMB package.
