Alarm Controls DE-1 Delayed Exit Timer

Designed to protect controlled exits without compromising safety, the Alarm Controls by ASSA ABLOY DE-1 Delayed Exit Timer is a Door Release Button built for commercial access control. The DE-1 secures exit doors with an audible alarm on unauthorized openings while allowing emergency egress when required. A 2-second nuisance delay minimizes false alarms from accidental presses, and the key-switch reset ensures doors stay secure until authorized personnel re-lock them—field wiring can also allow auto re-locking for flexible deployment. Users get immediate feedback from the hi-brightness illuminated 2" green pushbutton, countdown buzzer and flashing lamp during timing mode, improving compliance and occupant confidence. Built on a stainless steel double-gang wall plate with N/O and N/C contacts rated at 10A (35 VDC / 120 VAC), the DE-1 integrates seamlessly into existing access control, security and surveillance systems. Ideal for schools, healthcare, retail and commercial buildings where monitored egress and reliable door release are essential. Add the DE-1 to your access control design or contact our sales team to specify it for your next security project.
