SDC 280AHV Conventional Direct Throw Surface Mount Electric Bolt Lock, Failsecure, Dull Aluminum

Protect critical openings with dependable failsecure performance. The Security Door Controls SDC 280AHV electric bolt lock (electrified deadlatch) delivers consistent, tamper-resistant locking for access control, surveillance and security monitoring applications. Designed for surface mount use, the 280AHV installs quickly in retrofit and new construction scenarios and integrates with existing control panels thanks to field-selectable 12V/24V operation and built-in voltage/current spike protection. An automatic relock switch keeps the bolt retracted while the door is open and projects it on closure to reduce mechanical errors and enhance user throughput. The stainless steel bolt and dull aluminum finish provide durable, low-maintenance protection backed by a 5-year limited warranty. Ideal for high-traffic doors, closets, cabinets and secure enclosures, this electrified deadlatch supports failsecure applications where maintaining a locked state during power loss is required.
