About PIR Shed Alarm
Highly reliable at detecting motion and featuring a low false alarm rate, PIR (passive infrared) shed alarms are ideal systems to protect sheds and other remote locations. PIR alarms are Normally Closed (NC) devices, meaning that the circuit is usually closed, and only opens when it detects movement. When the circuit opens, it triggers an alarm, or in some cases, dials a preset number. Buyers can choose from many different types of PIR shed alarms including wireless ones as well as hard wired systems on eBay. Top-rated Sellers also offer other alarms including remote shed alarms and garden shed alarms, often with free shipping throughout the UK.
