Seco-Larm Enforcer Mini No-Cut Electric Door Strike SD-991A-D1Q – Fail-Secure

Overview

The Seco-Larm Enforcer Mini No-Cut Electric Door Strike (Fail-Secure) turns a standard cylindrical lock into an electronic access-control point with minimal door-frame modification. This no-cut variant is designed to fit most metal or wooden doors, requiring only the frame cut necessary to accommodate the strike hole. It connects quickly to access-control or egress devices via a simple 2-wire, non-polarized setup, and its reversible, non-handed design adapts to either left- or right-handed doors.

With fail-secure operation, the door remains locked when power is lost, helping you maintain controlled entry. The 1,000-pound static holding force provides a robust sense of security, while the stainless steel keeper delivers durability for long-term use. The striker ships with both a stainless steel no-cut strike plate and a silver aluminum low-cut strike plate, ready to fit a wide range of cylindrical locksets. An optional bronze-colored low-cut strike plate is also available (sold separately – SD-991RA-61Q/B). All required installation hardware is included for a streamlined setup. This unit is intended for indoor use and is powered by a 12VDC solenoid, not a buzzer coil.
