DSC BV-501 'A' Alarm Contact and Tamper Switch

Bring dependable intrusion detection to residential and light-commercial systems with the DSC BV-501 'A' — a PIR motion sensor with integrated alarm contact and tamper switch. Designed for reliable security and surveillance, this wired DSC motion sensor uses patented Multi-Level Signal Processing (MLSP) and temperature compensation to detect human IR reliably, even in challenging temperature conditions. Installers benefit from sensitivity adjustment for normal or hostile environments, while high-level static/transient protection and excellent RF and white-light immunity keep monitoring stable in electrically noisy sites. The BV-501’s digital signal analysis provides consistent coverage across the protected area, reducing false alarms and maintenance callbacks. Compact, white finish and wired connectivity make it easy to integrate into existing panels and monitoring systems. Choose the DSC BV-501 'A' for a practical, high-performance sensor that strengthens your intrusion detection and monitoring strategy—order now to upgrade perimeter and interior surveillance reliability.
