Seco-Larm SD-995C: Fail-Safe or Fail-Secure Electric Door Strike for Metal Doors – 1000 lbs Static Strength

Overview

The Seco-Larm SD-995C is a heavy-duty electric door strike designed for metal doors that demand adaptable security. Unlike fixed options, this unit can be field-programmed in seconds to operate as fail-safe (locks when power is applied) or fail-secure (locks when power is removed), giving you installation flexibility without swapping hardware.

Key features at a glance

• Field-selectable for fail safe or fail-secure operation
• Reversible non-handed design fits either right-handed or left-handed doors
• Shallow profile that works with most metal doors
• Powered by a solenoid, not a buzzer coil
• Stainless-steel keeper for strength and long life

With an impressive static strength, this strike offers reliable performance for high-traffic entrances. The durable stainless-steel keeper resists wear, while the solenoid activation delivers smooth, quiet operation that won’t misalign the door frame over time.

Durability meets practical design

This model is built for years of service in commercial settings. The shallow design minimizes door modification, while the field-programmable option supports changing security requirements without swapping hardware. It is compatible with virtually any cylindrical door locking system on metal doors.

Real-world use cases can include storefronts, warehouses, offices, or maintenance rooms where security access and door handling need to adapt to changing needs. The SD-995C is designed to integrate with existing locks, providing an added layer of control without locking you into a single configuration.

What to expect during installation and use

• Plan for a straightforward retrofit on metal doors with standard cylindrical locks.
• Choose fail-safe or fail-secure to match your access-control strategy.

Note that while it is a robust, field-programmable solution, you should verify compatibility with your current locking hardware and power environment before installation. This approach helps ensure smooth operation and longevity.

Practical benefits and use cases

Expect a seamless door experience with precise engagement, reduced wear on the door frame, and flexibility to adapt to changing access policies. The combination of a solenoid drive and stainless keeper means consistent performance in busy entryways.

• Flexible configurations support varying security workflows
• Long-lasting components reduce maintenance and downtime
• Broad compatibility with cylindrical locking systems on metal doors
