Camden CX-DA300 CX-DA300 Series Line Powered Door Monitor Alarm with Relay and Reset Key, Double Gang, 12/24V AC/DC

Stop unattended doors from becoming security blind spots. The Camden Door Controls CX-DA300 series line powered door monitor alarm delivers reliable local audible notification and monitoring for doors that are propped, held open, or otherwise unsecured. Designed for commercial and institutional deployments, this double-gang door alarm features a heavy-duty stainless steel faceplate for long-term durability and vandal resistance.

With adjustable alarm delay (0–60 seconds) and a programmable relay output, the CX-DA300 gives security integrators and facility managers flexible control—silencing brief authorized holds while ensuring true violations trigger alerts and upstream security systems.

Ideal for schools, hospitals, retail and office buildings where door monitoring and perimeter security are critical, the Camden CX-DA300 door alarm reduces false alarms, speeds incident detection, and strengthens overall security posture.
