What Is an Electric Strike?

An electric strike replaces the standard strike plate in your door frame. When it receives a signal, a hinged keeper swings free so the latch can pass through. Your existing lockset stays in place, and the key still works. That makes an electric strike the simplest, lowest-cost way to add access control to an existing door. It connects easily to card readers, keypads, intercoms and push-to-exit buttons. Most commercial models run on 12 or 24 volts and work with both cylindrical and mortise lock types.

Choosing the Right Electric Strike

The right electric strike depends on your door, frame, lock and safety needs. Use these five key factors to narrow your choice, or ask our team to assess the door and recommend the best model.

Fail-Safe vs. Fail-Secure Electric Strikes

This choice shapes how your door behaves during a power outage. A fail-secure strike stays locked when power is lost. A fail-safe strike unlocks when power is lost. In both cases, people inside can still exit by turning the lever.

Most exterior and perimeter doors use fail-secure strikes to protect the building during an outage. Fail-safe models suit some stairwell and interior doors where re-entry must work in an emergency. Fire-rated doors require fail-secure strikes.

Match the Strike to Your Lockset

Electric strikes are built for specific lock types. Cylindrical and mortise locks with a latchbolt use standard strikes. Rim exit devices need a surface-mounted strike that fits the device’s rim latch.

Deadbolts cannot pass through most electric strikes, so they must stay retracted or be removed. Check the latch length, deadlatch position and backset before ordering. A mismatched strike may bind or fail to release. A quick site check by a pro prevents these problems.

Hollow Metal, Aluminum or Wood Frames

Your frame decides which strike body fits. Steel frames are the most common choice in commercial buildings. Hollow metal frames accept the common 4-7/8 inch strike prep. Aluminum storefront frames have narrow profiles and need slim strikes made for that space.

Wood frames need careful mortising to keep the jamb strong. Each material also changes how wiring reaches the strike. Measuring frame depth and stile width first helps you avoid costly cutting or frame damage.

Voltage, Current and Power Supply

Most electric strikes run on 12 or 24 volts, either AC or DC. Many newer models let you select the voltage in the field. The strike must match the output of your access control panel or a dedicated power supply.

Continuous duty strikes can stay unlocked for long periods without overheating. AC power causes a buzz, while DC runs quietly. Long wire runs need the right wire gauge to avoid voltage drop and weak release.

Fire Ratings and Code Compliance

Fire-rated doors need a UL-listed, fail-secure electric strike that keeps the door latched during a fire. Look for UL 10C listing and ANSI/BHMA A156.31 grading on commercial openings. Using a non-listed strike can void the door’s fire label.

Your local fire marshal enforces NFPA 80 and NFPA 101 rules for egress and latching. Healthcare and government buildings often face extra inspections. We always confirm labels and ratings before we install any strike on your doors.

Electric Strike vs. Magnetic Lock

Electric strikes and magnetic locks both control access, but they work in different ways. This side-by-side look shows where an electric strike gives you a safer and more flexible choice.
