Burglar alarm PCBs serve as the intelligent control core of security systems, engineered to real-time process and validate analog/digital signals from PIR motion sensors, magnetic door/window contacts, glass-break detectors and vibration sensors, accurately distinguishing unauthorized entry from false triggers via programmable logic algorithms. Optimized for 24/7 battery-powered operation with ultra-low quiescent current (≤50μA in standby), these PCBs integrate tamper-proof circuits that trigger instant alerts upon physical tampering or disconnection. They support dual wired/wireless communication (GSM/LoRa/Wi-Fi) for seamless signal transmission to security monitoring centers, with robust anti-interference shielding layers and surge protection (up to 2kV) ensuring reliable alarm activation and data transmission in residential, commercial and industrial premises.
