Electric Strikes

Electric strikes replace the fixed strike plate in a door frame with an electromechanical unit that releases on command, allowing a door to be pushed or pulled open without retracting the latch bolt. They are the default door control device on most commercial access control openings.

Plan Your Deployment

Fail-safe (unlocks on power loss) vs. fail-secure (stays locked)
Voltage (12/24 VDC or 12/24 VAC) and current draw (holding and inrush)
Frame material: hollow metal, aluminum, or wood
ANSI/BHMA grade and static strength rating
Latch monitoring, door position, and tamper signals required

Access Control Guide Get Recommendations

What to Look For

Fail-secure is the standard on most interior commercial openings; fail-safe is required on stair doors, areas of refuge, and egress paths where local code demands free exit. Match voltage to the existing door control panel. ANSI Grade 1 strikes are rated for the heaviest commercial cycles and are recommended on high-traffic doors.

Common Deployment Scenarios

Electric strikes are used on perimeter storefronts, tenant entries, office suite doors, and interior security-zone doors. They are commonly paired with a request-to-exit sensor and door position contact to complete the opening monitoring required by audit trails.

What to Look For When Buying

The decisions that matter most before you spec.

Fail-Safe vs. Fail-Secure Behavior

Choose fail-safe (de-energize to unlock) for life-safety egress and fire exits; choose fail-secure (de-energize to remain locked) for secure perimeters and restricted zones. Your access control logic and facility code compliance drive this decision. Mixing modes across a site creates confusion during emergencies—standardize where possible.

Voltage & Power Supply Architecture

Most electric strikes draw 0.5–1.2 A at 12V or 24V DC. A single access control panel can typically power 4–8 strikes directly; beyond that, use door relays and power distribution modules to isolate surge and prevent voltage drop across long runs. Plan power budgets at design time to avoid undersizing PSUs mid-deployment.

Frame Type & Installation Complexity

Surface-mount strikes retrofit existing frames in 30 minutes; mortise strikes require frame chiseling and are slower in retrofit but deliver cleaner aesthetics in new builds. Hollow metal frames are easiest; wood frames require careful layout to avoid studs. Measure your existing latch bolt diameter and frame pocket depth before ordering.

Latch Bolt Compatibility & Strike Plate Geometry

Electric strikes come in different aperture widths (typically 1–1.25 inches) and depths to match standard latch bolts. Measure your door's existing bolt diameter and frame pocket depth; mismatched geometry will cause binding, incomplete release, and nuisance alarms. Mechanical locking bolts and relays may complement strikes in multi-point or high-security installations.

Solenoid Duty Cycle & Holding Force

High-traffic public doors (100+ cycles per day) demand strikes rated for continuous duty and robust solenoid design. Lower-cycle secure access points can use standard-duty units. Check the manufacturer's cycle rating and temperature operating range, especially in outdoor or uncontrolled environments where coil performance degrades.

Integration with Surveillance & Monitoring

Electric strikes generate audit trails when wired to access control panels with door-position sensors or forced-entry detection. Pair strikes with IP cameras at entry points to correlate access logs with video. Redundant power and failover logic prevent access-control outages during system stress; design for graceful degradation if the strike loses power.

Technology Stack

The specs and acronyms that actually affect electric strikes performance.

Fail-Safe vs. Fail-Secure

Fail-safe (electric latch release) unlocks when power is removed—required on fire exits and emergency egress. Fail-secure (electric deadbolt) remains locked without power—used on secure entries and restricted rooms. Verify your local fire/building code mandates before selecting either mode.

Solenoid Coil Voltage (12V DC / 24V DC)

12V draws more current (~1 A) but is cheaper; 24V draws less current (~0.6 A) and allows longer cable runs with less voltage drop. Match your power supply and control panel ratings; do not mix voltages on the same circuit without isolation relays.

Holding Force (in pounds or newtons)

Typical electric strikes hold 800–1,500 pounds of retaining force. Higher force is unnecessary for standard swing doors but may be specified for high-wind exterior doors or manual attempts to force entry. Verify force rating does not exceed your door hardware's structural limit.

Duty Cycle (Continuous vs. Intermittent)

Continuous-duty strikes can energize indefinitely without thermal derating. Intermittent-duty units are rated for shorter engagement periods (e.g., 5 seconds per activation). High-traffic doors demand continuous-duty; secure-access doors can use intermittent to reduce power consumption.

Surface-Mount vs. Mortise Installation

Surface-mount bolts to the frame exterior—faster retrofit, no frame machining. Mortise recesses into the frame pocket—requires chiseling, cleaner finish, standard in new construction. Choose based on installation timeline, frame type, and aesthetic requirements.

Strike Aperture Width & Latch Compatibility

Standard apertures are 1 inch (for 7/8″ latches) or 1.25 inches (for 1″ latches). Measure your existing latch bolt diameter; oversized or undersized apertures cause binding, incomplete release, and access-control failures. Always verify cross-compatibility before installation.

Typical Deployment Scenarios

Office Building Entry Lobby (6 revolving + sliding doors)

Six fail-safe electric strikes on glass entry doors, controlled by a single 24V access control panel with exit buttons and card readers. Use a 24V 5-amp power supply to handle simultaneous door releases during fire alarm activation. Wire each strike through isolation relays to prevent solenoid inrush from collapsing panel voltage.

Secure Server Room & Data Center (3 doors)

Three fail-secure mortise strikes on hinged steel doors protecting equipment rooms. Each strike energizes only on valid credential + biometric confirmation, defaulting to locked if power or panel fails. Integrate door-position sensors with IP camera recording to audit physical access and correlate with system logs.

Multi-Tenant Building Stairwell & Egress (8 doors)

Eight fail-safe surface-mount strikes on stairwell exit doors to comply with fire code. All strikes de-energize on fire alarm signal, allowing egress without card readers. Size 24V power supply for simultaneous release of all eight solenoids (assume 0.8 A per strike = 6.4 A total); use relay modules to distribute control signals and avoid panel overload.

Warehouse Loading Dock & Secured Receiving (4 bays)

Four fail-secure strikes on steel bay doors with magnetic locks on secondary access points. Strikes energize only during scheduled receiving windows; motion sensors and overhead cameras detect unauthorized access. Design with redundant 12V power supplies to survive a single PSU failure without losing security.

Frequently Asked Questions

What is the difference between an electric strike and a magnetic lock?

An electric strike replaces the fixed strike plate in a standard door frame and releases the latch bolt on command—the door hardware (handle, latch, hinges) remains unchanged. A magnetic lock mounts on the door frame and holds the door shut via electro-magnetic force, independent of mechanical latches. Strikes are faster to retrofit into existing doors; magnetic locks are more visible and suitable for glass or aluminum frame installations. Both fail-safe and fail-secure options exist for each type.

Do I need a relay to control an electric strike from my access control panel?

Most modern access control panels have built-in relay outputs rated for one or two strikes per output (typically 2–5 A at 12V or 24V). For one or two doors, direct wiring works fine. For more than two strikes, or if the panel output is undersized, use isolation relays or door controller modules to prevent inrush current from collapsing the panel's power rail. Always add a suppression diode across the solenoid coil to protect the relay.

Can I use a 12V strike and a 24V strike on the same access control system?

Technically yes, but it complicates power distribution and introduces risk. A single panel output energizes one voltage; mixing 12V and 24V strikes on the same circuit requires separate power supplies and relays, increasing wiring complexity and failure modes. Best practice is to standardize on one voltage across your entire facility (usually 24V for long cable runs and lower current draw).

What should I do if my electric strike buzzes or chatters when energized?

Buzzing indicates a weak solenoid pull or inadequate power supply voltage. Check for: (1) voltage drop in the cable run—measure voltage at the strike solenoid, not at the panel; (2) undersized power supply—strikes typically draw 0.5–1.2 A; (3) a shorted suppression diode. If voltage is below 11V (for 12V units) or 23V (for 24V units), add a dedicated power supply or upgrade wire gauge. If the solenoid is mechanically stuck (lint, corrosion), clean or replace the strike.

How do I ensure my electric strike is fail-safe on power loss?

A fail-safe strike is energized in the locked state; power loss de-energizes the solenoid, releasing the latch bolt to allow egress. Verify: (1) the strike model is rated fail-safe (not fail-secure); (2) the access control logic is wired to de-energize the relay output on alarm or power loss (many panels default to de-energize); (3) you have redundant or sufficient capacitor-backed battery backup on the power supply to handle a clean shutdown if mains power fails. Test the strike manually by disconnecting power and confirming the bolt releases.

What is the typical holding force of an electric strike, and does it matter for my door?

Standard electric strikes hold 800–1,500 pounds of retaining force—far more than needed for a manually-opened swing door. Higher force specifications matter only for: (1) exterior doors in high-wind areas (test per local building code); (2) doors subject to intentional forced-entry attempts (rare outside banks or secure facilities); (3) oversized or high-mass doors. For typical office or warehouse doors, a 1,000-pound strike is adequate. Always verify your strike's force rating does not exceed your latch bolt or frame's structural limits.
