SDC EA-728V EA Series Double Gang Door Prop Alarm with Keylock Reset/Bypass, (Replaces 728U)

Designed to stop unsecured doors from becoming security risks, the Security Door Controls EA-728V Door Prop Alarm delivers reliable audible protection and easy system integration for modern access control environments. The EA Series unit issues an 85 dB piezo alarm when a door is propped open, and its adjustable timed delay lets you tune responses to match building traffic and reduce false alerts. Built for B2B installations, the EA-728V mounts in a double-gang box, accepts 12 or 24 V DC power, and provides two output relays for remote monitoring and logging to your security or surveillance system.

Maintenance and operations staff benefit from the vandal-resistant aluminum enclosure and the optional keylock reset/bypass, which allows secure, controlled overrides while preserving monitoring integrity. Simple wiring and universal mounting make this door alarm an affordable upgrade for existing access control setups or a standalone exit alarm solution. Ideal for campuses, hospitals, retail and commercial properties that require tight perimeter control—order the EA-728V to strengthen your access control and monitoring strategy.
