Securitron -u.s. BA-DPA-24 Door Prop Alarm Timer

Product Description

The SECURITRON -U.S. BA-DPA-24 is a boxed door prop alarm timer designed to monitor and alert when a door is held open beyond a set time threshold. Operating at 24 volts, this unit mounts in a self-contained enclosure and activates an audible alarm when a door remains propped or ajar longer than the programmed delay. It is typically installed on fire doors, emergency exit doors, and access-controlled openings in commercial and institutional buildings. Licensed security technicians, access control integrators, and commercial locksmiths are the primary trades who specify and install this device.

The BA-DPA-24 is suited for commercial door applications where code compliance or security policy requires an audible warning when a door is left open. Common install locations include stairwell doors, loading dock exits, and secured corridor doors in schools, healthcare facilities, and office buildings. The self-contained boxed format simplifies installation where a discrete, all-in-one alarm timer solution is required without additional external enclosures.
