Seco-Larm SD-997A-GBQ Electric Deadbolt Fail Secure Alarm Lock

The Seco-Larm SD-997A-GBQ is a fail-secure electric deadbolt designed for professional life-safety and access control applications. In a fail-secure configuration, the bolt remains locked when power is removed, ensuring that secured areas stay protected during a power interruption — a critical behavioral characteristic for high-security doors, server rooms, restricted access corridors, and other environments where unauthorized entry during an outage must be prevented. As a hardwired electric locking device, it integrates into broader access control ecosystems, accepting a control signal from an access controller, keypad, or relay output to retract the bolt and permit entry. Seco-Larm is a well-established manufacturer of commercial-grade security hardware, and the SD-997A-GBQ reflects their focus on reliable electromechanical construction suited for demanding commercial and institutional installations.

Key features & benefits

• Fail-Secure Operation — The deadbolt remains in the locked position whenever power is interrupted, preserving the security of the protected space during outages or system faults — the correct behavioral mode for high-security and restricted-access applications.
• Electric Deadbolt Mechanism — Electromechanical deadbolt actuation allows the lock to be remotely controlled by an access control system, eliminating the need for mechanical key operation at the controlled point of entry.
• Commercial-Grade Construction — Manufactured by Seco-Larm, a recognized commercial security hardware brand, supporting integration into professional life-safety and security installations.
