Securitron BA-DPA-12 Door Prop Alarm Timer, 12VDC with Boxed Alarm

Keep entry points secure and compliant with the Securitron BA-DPA-12 Door Prop Alarm Timer — a purpose-built door alarm that detects and deters doors left propped open. Designed for commercial and institutional environments, this analog timer monitors door status and triggers a clear audible piezo alarm and LED indicator when a door remains open beyond a preset interval. The BA-DPA-12 supports three 5 Amp SPDT outputs for simultaneous local and remote signaling, simplifying integration with access control panels, security monitoring systems, or building automation. With tamper-detection capabilities and a convenient bypass mode for authorized egress, it minimizes nuisance alarms while maintaining continuous protection. The 12VDC power and surface-mount form factor make installation straightforward on most frames and strike setups. Ideal for high-traffic lobbies, loading docks, and secure perimeter doors, the Securitron door prop alarm enhances your physical security and surveillance strategy by reducing tailgating and unattended doors. Add the BA-DPA-12 to your access control and monitoring system to strengthen site security and streamline incident response.
