Command Access DS1+ Delay Sequencer Board

The Command Access DS1+ Delay Sequencer Board delivers precise, dependable timing control for access control and commercial door systems. As a dedicated control panel board from Command Access Technologies, the DS1+ sequences (de)energizing of electrified locks and, after an adjustable interval, activates automatic door operators—preventing premature engagement and minimizing hardware stress. Installers and integrators benefit from three adjustable delays (up to 30 seconds), bi-directional sequencing for one- or two-way door flows, and flexible 12V/24V AC or DC outputs to match common lock and operator power requirements. For telephone entry applications, the DS1+ offers a direct connection to entry panels, simplifying wiring and removing the need for extra isolation relays. Built for security-focused environments, it supports reliable monitoring and surveillance integration while providing options for one-shot security outputs or maintained outputs for smoke evacuation. Ideal for commercial buildings, multifamily housing, and institutional sites, the DS1+ streamlines installation and enhances system reliability. Add the DS1+ to your next access control or telephone entry project to improve door sequencing and system uptime—contact sales to order or request technical support.
